SYSTEMS AND METHODS FOR PROVIDING CONTENT BASED ON MULTIPLE ANGLES

SYSTEMES ET PROCEDES POUR FOURNIR UN CONTENU SUR LA BASE D'ANGLES MULTIPLES

English Abstract

Systems and methods are described herein for identifying camera angles, based on network parameters, for content available at multiple camera angles. The system determines a network parameter of a network used to provide content that is recorded or rendered at various camera angles. The determined network parameters are used to identify camera angles that are supported by the network. For example, the video data associated with a camera angle having a prerequisite bit rate of 5 Megabits per second is supported by a network having a bandwidth parameter of 40 Mbps, while another camera angle having a prerequisite bit rate of 45 Megabits per second is not supported by the bandwidth parameter of 40 Mbps. The system provides the video data for identified camera angles supported by the network to a device for display.

French Abstract

L'invention concerne des systèmes et des procédés pour identifier des angles de caméra, sur la base de paramètres de réseau, pour un contenu disponible à de multiples angles de caméra. Le système détermine un paramètre de réseau d'un réseau utilisé pour fournir un contenu qui est enregistré ou rendu à différents angles de caméra. Les paramètres de réseau déterminés sont utilisés pour identifier des angles de caméra qui sont pris en charge par le réseau. Par exemple, les données vidéo associées à un angle de caméra ayant un débit binaire prérequis de 5 mégabits par seconde sont prises en charge par un réseau ayant un paramètre de bande passante de 40 Mbp, tandis qu'un autre angle de caméra ayant un débit binaire prérequis de 45 mégabits par seconde n'est pas pris en charge par le paramètre de bande passante de 40 Mbp. Le système fournit les données vidéo pour des angles de caméra identifiés pris en charge par le réseau à un dispositif pour l'affichage.

SYSTEMS AND METHODS FOR PROVIDING CONTENT BASED ON MULTIPLE
ANGLES
Background of the Invention
[0001] The present disclosure is directed to digital content delivery, and
more particularly,
to providing content based on camera angles at which video data of the content
was captured.
Summary
[0002] Video content is often captured at various angles. For example, a
football match is
filmed with multiple cameras, each positioned at a different angle to capture
the match.
Digitally generated content such as video games is also rendered at various
angles. For
example, a video game allows a user to select which angle he wants to play
using his avatar
(e.g., looking behind or in front of his avatar). As communication systems
support increasing
network bandwidths, these angles may be provided to a device (e.g., a
smartphone) through a
streaming service offered by content providers such as ESPN and Steam.
However,
parameters of a network such as network bandwidth or download speed affect the
amount of
video data capable of being provided to a device on the network. Having
multiple angles of
content may overwhelm a consumer who is unable to determine the angle that is
likely to be
of interest. In order to address these issues, a content application is
provided that identifies
one or more of the multiple camera angles available based on network
parameters, likelihood
of interest, or a combination thereof
[0003] Systems and methods are described herein for providing content based on
camera
angles at which video data of the content was captured. As used herein, a
"camera angle"
refers to a vantage point at which a content item is recorded or rendered for
consumption. A
- 1-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
physical camera may generate one or more camera angles or a graphics
production program
may render one or more camera angles of digitally animated content.
[0004] In some embodiments, a content application causes video data for one or
more
camera angles of multiple camera angles to be provided to a device based on a
network
parameter. The content application determines a network parameter for a
network over
which a content item, including video data for multiple camera angles, is
provided to the
device. The content application identifies one or more of the camera angles
for which to
provide video data using the network based at least in part on the network
parameter. The
content application then causes the video data to be provided to the device
for the identified
one or more camera angles.
[0005] The content application may determine the network parameter by
determining at
least one of a network bandwidth, a number of users on the network, a maximum
download
speed, any suitable performance metric of a network, any suitable usage metric
of a network,
or any combination thereof. The camera angles for which video data is provided
may be
identified based on a predefined distribution of camera angles spanning 360
degrees. For
example, camera angles may be provided such that the distribution of camera
angles evenly
covers angle values spanning 360 degrees (e.g., a three-angle distribution is
predefined to be
angles closest to 0 degrees, 120 degrees, and 270 degrees). In some
embodiments, the
content application identifies which camera angles for which to provide video
data based on a
user indication of a camera angle. For example, the user indication of a
camera angle may
include a change in the orientation of the device (e.g., a user tilts the
device by 25 degrees).
In some embodiments, the content application provides a notification, to the
device,
indicating that the network will not adequately support the video data
corresponding to the
camera angle associated with the user indication. For example, a user tilts
the device 25
degrees to select an angle at 180 degrees, and the system provides a
notification that the
download speed is not sufficient for the video data associated with the camera
angle of 180
degrees to be provided. In some embodiments, the content application causes
video data for
the camera angles to be provided, to the device, by communicating video data
addresses (e.g.,
URLs) corresponding to the camera angles.
[0006] In some embodiments, a content application causes video data for one or
more
camera angles of multiple camera angles to be provided to a device based on an
identification
of camera angles likely to be of interest. The content application may make
the video data
for the camera angles available to the device. In some embodiments, the
content application
dynamically identifies camera angles that are likely to be of interest. In
some embodiments,
- 2-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
camera angles are pre-curated such that the camera angles that are likely to
be of interest are
determined before the video data for the camera angles is made available to
the device. The
content application may cause the video data for the camera angles identified
to be likely of
interest to be provided to the device.
[0007] In some embodiments, the content application dynamically identifies the
camera
angles by identifying that one or more camera angles are likely to be of
interest relative to
other camera angles of the multiple camera angles. The content application
may, to identify
camera angles likely to be of interest relative to other camera angles,
determine that an
enlarged depiction of an object is presented in a camera angle. For example,
an enlarged
depiction of a court boundary is presented on a camera angle that clearly
shows that an
athlete has stepped out of bounds. The content application may identify camera
angles likely
to be of interest relative to other camera angles by determining that a view
of an event being
depicted is unobstructed. For example, the content application identifies a
camera angle that
follows the trajectory of a soccer ball across a field without any player
blocking the view of
the soccer ball. The content application may, to identify camera angles likely
to be of interest
relative to other camera angles, determine a ranking of the multiple camera
angles. For
example, the content application ranks camera angles in an order of most to
least likely to be
of interest. The content application may cause visual indicators indicative of
the determined
ranking to be displayed at the device. For example, the content application
may display
buttons for each provided camera angle, and a top percentile of the ranked
camera angles may
have a unique color as a visual indicator of the high ranking. The
identification of a camera
angle as likely to be of interest may be further based on historical data,
empirical data, real-
time statistics, or a combination thereof In some embodiments, the content
application
dynamically identifies the camera angles by determining camera angles that are
likely to be
of interest based on historical data. For example, historical data of camera
angles for
basketball games shows that the camera angle of 90 degrees is most popular
among users
after a dunk is made (e.g., the angle depicting the reaction of players on the
bench). Real-
time statistics suggest, in some embodiments, that a camera angle is likely to
be of interest
(e.g., the largest percentage of users are consuming a camera angle in real-
time). In some
embodiments, the video data corresponds to a real-time broadcast (e.g., a live
stream of an
event), prerecorded content item (e.g., a highlight reel), or a combination
thereof (e.g., the
live stream of an event augmented with a highlight reel of related events).
The content
application may make the video data for the camera angles available to the
device by

providing, to the device, video data addresses (e.g., URLs) hosting the video
data
corresponding to the camera angles.
[0008] It should be noted that the systems, methods, apparatuses, and/or
aspects described
above may be applied to, or used in accordance with other systems, methods,
apparatuses,
and/or aspects described in this disclosure.

Detailed Description of the Drawings
[0019] FIGS. 1A-1C show an illustrative embodiment of a process for consuming
content
captured at multiple camera angles, in accordance with at least some
embodiments of the
disclosure. Device 101 is an electronic device capable of displaying video
data of content
that is captured at multiple camera angles. As depicted through FIGS. 1A-1C, a
cricket
match captured at camera angles 120-129 is displayed on device 101. FIG. 1A
shows an
embodiment of a content application providing a content item to device 101 for
consuming a
cricket match at camera angles 120-129. FIG. 1B shows an embodiment of an
action that
may result in a change in the camera angle that is provided for display at
device 101. For
example, device 101 may receive user indications (e.g., a swipe across a
screen of a device)
that the user is interested in viewing camera angle 129. FIG. 1C shows a
change in video
data provided in response to the user indication.
[0020] As referred to herein, the terms "content item" and "media asset"
should be
understood to mean an electronically consumable user asset, such as television
programming,
as well as pay-per-view programs, on-demand programs, Internet content (e.g.,
streaming
content, downloadable content, or Webcasts), video, audio, playlists,
electronic books, social
media, applications, games, any other media, or any combination thereof Media
content
items may be recorded, played, displayed or accessed by devices. As referred
to herein,
"content providers" are digital repositories, conduits, or both of media
content items. Content
providers may include cable sources, over-the-top content providers, or other
sources of
content.
[0021] As referred to herein, a "device" should be understood to mean an
electronic device
capable of providing media content for consumption directly to a user. Devices
include
smartphones, tablets, virtual reality headsets, televisions, any other
electronic device for
content consumption, or any suitable combination thereof As referred to
herein, a "content
application" includes any suitable software, hardware, or both for
implementing the features
described herein. The content application may be implemented either entirely
or partially on
a device such as device 101. When implemented partially on device 101, the
content
application may be further partially implemented using any other suitable
equipment located
either locally to device 101 or remotely from device 101. The content
application, in some
embodiments, functions as a platform for content delivery on a device. In such
embodiments,
the content application is in either direct or indirect communication with one
or more content
providers using any suitable communication channels.

[0022] Although depicted in the user interface for added clarity, the axes
corresponding to
the angles within 360 degrees and the angle labels of 0 degrees, 90 degrees,
180 degrees, and
270 degrees are not necessarily provided for display by the content
application. Camera
angles 120-129 are associated with digital buttons displayed in the interface
on device 101.
Although not depicted, there may be additional camera angles available for
display at device
101. For example, a total of 50 camera angles are available to be provided to
device 101.
The content application may determine a subset of the available angles to
provide to device
101.
[0023] In some embodiments, camera angles 120-129 are determined by the
content
application based on network parameters. Network parameters include network
bandwidth,
number of users on the network, a maximum download speed, any suitable
performance
metric of a network, any suitable usage metric of a network, or any
combination thereof For
example, the content application determines the network bandwidth (e.g., a
maximum
capacity for uploading and downloading data determined by an Internet service
provider or
communications equipment) and provides camera angles 120-129, whose total
bandwidth
requirements are satisfied by the network bandwidth. The content application
may determine
the number of users on a network and, based on the number of users, determine
which camera
angles to provide. For example, if there are no other users or devices on the
network, the
content application determines that the full network bandwidth is dedicated to
the device and
identifies camera angles based on the full network bandwidth. If there are N
users on the
network, the content application may divide the network bandwidth by N and
determine
which camera angles to provide based on the resulting portion of the network
bandwidth. In
some embodiments, the content application may determine a maximum download
speed. For
example, the content application determines a maximum download speed of 90
megabits per
second (Mbps) and identifies camera angles such that the download speed
required to stream
the video data associated with the identified camera angles is not greater
than 90 Mbps.
[0024] The identification of camera angles to provide may be further based on
a predefined
distribution of camera angles within 360 degrees. The predefined distribution
may be such
that the camera angles are distributed evenly within 360 degrees. For example,
the content
application identifies, based on a total download speed of 90 Mbps, a first
set of three camera
angles located at approximately 120 degrees, 240 degrees, and 360 degrees,
each requiring 30
Mbps to download and a second set of two camera angles located at
approximately 45
degrees and 90 degrees, each requiring 45 Mbps to download. Although both sets
of camera
angles are supported by the network parameter, the first set may be preferred
over the second
- 6-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
because the camera angles are approximately evenly distributed within 360
degrees. In some
embodiments, a predefined distribution may be determined based on the event
depicted in the
content item. For example, a cricket field has positions in a circular
distribution such that
many angles within 360 degrees capture content of interest, while a video game
may have
content of interest primarily in front of an active avatar (e.g., a range of
approximately 200
degrees of the 360 degrees available). For camera angles associated with the
video game, the
predefined distribution may be within a range of 200 degrees rather than the
full 360 degrees
range.
[0025] A user indication may be used in the content application's
identification of camera
angles to provide video data for. A user indication includes a swipe on the
surface of a
device, a change in orientation of a device (e.g., a tilt), any suitable input
for requesting a
change in camera angle, or any combination thereof An orientation of a device
may be
measured by microelectromechanical system (MEMS) sensors such as gyroscopes
and
accelerometers to determine a change in orientation associated with a request
for a specific
camera angle. For example, the device may be at a first position and rotated
clockwise by 30
degrees to indicate that a user is selecting a camera angle that is
approximately 30 degrees
clockwise of the currently presented camera angle. The content application may
cause the
video data associated with the closest available angle (e.g., an angle
supported by the network
parameter) to be provided at the device. For example, the angle that is
clockwise by 30
degrees of the currently presented camera angle (e.g., currently at 90
degrees) is 60 degrees,
and the closest available camera angle to 60 degrees is at 50 degrees.
[0026] The content application may provide a notification to the device
indicating that the
network will not adequately support the video data corresponding to the camera
angle of the
plurality of camera angles. A camera angle may not be adequately supported
because of
incompatibilities related to formatting (e.g., 4K v. HD), content sources
(e.g., camera angles
provided from different content sources, where one uses an unsupported network
protocol),
permissions issues (e.g., a paywall), security issues (e.g., a firewall), or
any combination
thereof. Using the previous example with a 30 degrees clockwise rotation, a
camera angle at
60 degrees may require a 100 Mbps download speed while the network can support
a
maximum download speed of only 90 Mbps. In some embodiments, the content
application
provides a notification that the video data at a camera angle of 60 degrees is
not adequately
supported by the download speed network parameter.
[0027] The content application may communicate video data addresses
corresponding to
the camera angles. For example, as shown in FIG. 3, URLs 320-329 are
associated with
- 7-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
respective camera angles 120-129. In some embodiments, the content application
provides
authorization to device 101 to access one or more of the URLs associated with
camera angles
120-129. For example, if 50 total camera angles are available for the cricket
match displayed
in FIGS. 1A-1C, the content application grants access to the device for only
camera angles
120-129.
[0028] In some embodiments, camera angles 120-129 are determined by the
content
application based on a likelihood of interest. A likelihood of interest in a
camera angle may
be determined relative to likelihoods of interest in other camera angles. For
example, a
content application may determine that, of 50 total camera angles available,
camera angles
120-129 were more likely to be of interest as compared to the other 40 camera
angles. A
comparison may be based on what is depicted in camera angles 120-129 as
compared with
what is depicted in the other 40 camera angles. For example, camera angles 120-
129 depict
cricket players at all times because they capture players stationed at
designated cricket field
positions (e.g., long stop), while the other 40 camera angles capture the
grass between players
or the audience in the bleachers.
[0029] The content application may identify which camera angles are likely to
be of interest
relative to other camera angles by determining that an enlarged depiction of
an object is
presented in certain camera angles. For example, certain camera angles capture
a larger
depiction of a boundary or edge of a playing field than is captured by other
angles. In some
embodiments, the content application identifies camera angles that are likely
to be of interest
relative to other camera angles by determining that a view of an event being
depicted is
unobstructed. For example, certain camera angles present unobstructed views of
the cricket
bat while others have players blocking the view of the cricket bat. The
content application
may perform image processing on the video data to determine the relative sizes
of an object
depicted in multiple camera angles. The content application may perform image
processing
on the video data and determine representation of the entire event captured by
the camera
angles to identify obstructions in the way of an object of interest. For
example, the content
application uses image processing to identify players and equipment such as
the cricket ball.
Based on the identified objects and angles at which they are taken, the
content application
may determine what objects could possibly be depicted at each angle and
determine objects
are obstructed at an angle if they are not depicted at the respective angle.
[0030] In some embodiments, the content application identifies camera angles
that are
likely to be of interest relative to other camera angles by determining a
ranking of the camera
angles. The ranking may be based on historical data or a comparison of what is
depicted in
- 8-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
each camera angle. For example, the content application ranks camera angles
according to a
usage metric (e.g., how many users have accessed or are currently accessing
the camera
angle). The camera angles are ranked, in some embodiments, based on image
processing of
what is depicted within each camera angle. For example, the content
application ranks
camera angles according to the degrees to which an enlarged depiction of an
object is
available (e.g., ranked from most enlarged depiction to least).
[0031] The content application may cause visual indicators to be provided for
display at a
device. The visual indicators are indicative of a determined ranking of the
camera angles. As
shown in FIG. 2, visual indicators are associated with the video data provided
for camera
angles 222, 229, 221, and 223. Visual indicators may reflect a higher-ranked
camera angle
(e.g., camera angles 222 and 229) or a lower-ranked camera angle (e.g., camera
angles 221
and 223).
[0032] A likelihood of interest in a camera angle may be determined based on
historical
data. Historical data includes usage metrics for the camera angles of a
content item. For
example, a histogram of the number of users viewing camera angles over time
may be used to
determine the camera angle most likely to be of interest at different times in
the content item.
The content application may also use the number of users who have requested or
are
requesting a camera angle to determine that the camera angle is likely to be
of interest.
[0033] The video data associated with the camera angles is, in some
embodiments, of a
real-time broadcast. For example, a cricket game that is broadcast at multiple
angles live is
made available to a device by the content application. In some embodiments,
the video data
associated with the camera angles is of a prerecorded content item. For
example, the sports
event that was broadcast live is recorded such that the video data for the
multiple camera
angles is available for consumption at the device. A movie or TV program that
is recorded
with multiple cameras is, in some embodiments, a prerecorded content item with
which the
content item applies the dynamic identification of camera angles as described
herein.
[0034] FIG. 2 shows an illustrative embodiment of an interface for consuming
content
captured at multiple camera angles, in accordance with at least some
embodiments of the
disclosure. A content item (e.g., a cricket match) is presented on device 201
based on
multiple camera angles capturing the match. The cricket match presented may be
a real-time
broadcast of a match, a playback of a prerecorded match, or a combination
thereof For
example, a real-time broadcast of a cricket match may be augmented with
prerecorded
highlights of a related match (e.g., a previous match between the two teams).
As shown in
FIG. 2, a content application may cause the video data for one or more camera
angles (e.g.,
- 9-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
camera angles 220-229) to be provided to device 201 with visual indicators
displayed
indicative of a ranking of the camera angles.
[0035] In some embodiments, the content application determines that a
predetermined
amount of the provided camera angles should be visually distinguished for
display at a
device. For example, the content application determines that the top 20% of
ranked camera
angles are to be associated with a visual indicator showing that their rank is
superior to the
ranking of other camera angles. As depicted in FIG. 2, camera angles 222 and
229 are
associated with visual indicators that indicate that camera angles 222 and 229
are superior to
camera angles 220, 221, and 223-228. The content application may change the
color,
brighten, or apply any suitable graphic effect for visually distinguishing a
digital button, or
apply any combination thereof to a digital button associated with a camera
angle. In some
embodiments, the content application provides visual indicators that
distinguish inferior
camera angles. For example, the content application determines that the bottom
20% of
ranked camera angles are associated with a visual indicator showing that their
rank is inferior
to the ranking of other camera angles. As depicted in FIG. 2, camera angles
221 and 223 are
associated with visual indicators that indicate that camera angles 221 and 223
are inferior to
camera angles 220, 222, and 224-229. The content application may provide
visual indicators
for display that darken associated camera angles 221 and 223.
[0036] FIG. 3 shows an illustrative data structure for providing content
captured at multiple
camera angles, in accordance with at least some embodiments of the disclosure.
In some
embodiments, a content item having video data associated with multiple camera
angles is
made available to a device through respective video data addresses (e.g.,
URLs). Video data
addresses 320-329 may correspond to camera angles 220-229, respectively. In
some
embodiments, video data addresses 320-329 are provided based on a network
parameter. The
content application may determine a network parameter of the network over
which the
content item is being provided to a device. For example, the network bandwidth
allows for
video data from video data addresses 320-329 to be transmitted because the
bandwidth
required for video data of camera angles 220-229 does not exceed the network
bandwidth. In
some embodiments, the content application provides authorization to the device
to access
video data addresses 220-229. For example, an additional security protocol is
implemented
such that the device having the video address to access is unable to download
the data at the
address due to lack of permissions set by the content application.
[0037] FIG. 4 shows a diagram of an illustrative system for providing content
based on
multiple camera angles, in accordance with at least some embodiments of the
disclosure.

Device 410 and content source 430 are communicatively linked through network
communication node 420. For example, a mobile phone may be linked to the
content source
of a streaming service such as Steam over a communication network (e.g.,
communication
network 420) enabled by a Wi-Fi router. Device 410 includes local memory 412,
display
414, and control circuitry (e.g., control circuitry 504 of FIG. 5). The
control circuitry further
includes camera angle identifier 413 for determining video data to provide to
display 414.
The determination may be based on user input from user input interface 411
(e.g., a tilt of a
smartphone indicating a desired camera angle). Although depicted as separate
from user
input interface 411, display 414 may a component of user input interface 411.
For example, a
.. touchscreen of a smartphone is capable of receiving user input through
swipes on the
touchscreen and displaying content items. Although depicted as a component of
device 410,
camera angle identifier 413 for identifying video data for camera angles of
the content item to
be provided at display 414 may be located in a remote server (e.g., at content
source 430).
[0038] The control circuitry or camera angle identifier 413 associated with
control circuitry
.. may perform any one portion of the entirety of the camera angle
identification process
described herein. For example, camera angle identifier 413 may determine a
network
parameter for the network of the communication link between network
communication node
420 and device 410 or for the network of the communication link between
content source 430
and device 410. Based on the determined network parameter, camera angle
identifier 413
.. may identify camera angles to request to be provided over the network. The
provided camera
angles are, in some embodiments, stored in local memory 412 such that camera
angle
identifier 413 provides them to display 414 with minimal delay. In some
embodiments,
camera angle identifier 413 dynamically identifies one or more of the
available camera angles
as likely to be of interest. Camera angle identifier 413 uses, in some
implementations,
.. historical data to dynamically identify the one or more camera angles. For
example, camera
angle identifier 413 determines that a number of users (e.g., a user number
exceeding a
threshold) accessed a camera angle indicative that the camera angle is likely
to be of interest.
Historical data may include current usage data. For example, camera angle
identifier 413
determines the number of devices to which content source 430 is currently
providing video
.. data for a camera angle. If the number of devices is above a threshold
number representative
of a sufficient likelihood of interest, camera angle identifier 413 identifies
the camera angle
as likely to be of interest.
[0039] Users may access content from one or more of their devices. FIG. 5
shows
generalized embodiments of a device capable of presenting content on a display
512. For
- 11-

example, display 512 may belong to a smartphone device. In another example,
display 512
may belong to a user television equipment system. User television equipment
system with
display 512 may include a set-top box 516. Set-top box 516 may be
communicatively
connected to speaker 514 and display 512. In some embodiments, display 512 may
be a
television display or a computer display. In some embodiments, set top box 516
may be
communicatively connected to user interface input 510. In some embodiments,
user interface
input 510 may be a remote-control device. Set-top box 516 may include one or
more circuit
boards. In some embodiments, the circuit boards may include processing
circuitry, control
circuitry, and storage (e.g., RAM, ROM, Hard Disk, or Removable Disk). In some
embodiments, circuit boards may include an input/output path. More specific
implementations of devices are discussed below in connection with FIG. 6. Each
one of
device 500 and user equipment system 501 may receive content and data via
input/output
(hereinafter "I/0") path 502. I/0 path 502 may provide content (e.g.,
broadcast
programming, on-demand programming, Internet content, content available over a
local area
network (LAN) or wide area network (WAN), and/or other content) and data to
control
circuitry 504, which includes processing circuitry 506 and storage 508.
Control circuitry 504
may be used to send and receive commands, requests, and other suitable data
using I/0 path
502. I/0 path 502 may connect control circuitry 504 (and specifically
processing circuitry
506) to one or more communications paths (described below). I/0 functions may
be
provided by one or more of these communications paths but are shown as a
single path in
FIG. 5 to avoid overcomplicating the drawing.
[0040] Control circuitry 504 may be based on any suitable processing circuitry
such as
processing circuitry 506. As referred to herein, processing circuitry should
be understood to
mean circuitry based on one or more microprocessors, microcontrollers, digital
signal
processors, programmable logic devices, field-programmable gate arrays
(FPGAs),
application-specific integrated circuits (ASICs), and may include a multi-core
processor (e.g.,
dual-core, quad-core, hexa-core, or any suitable number of cores) or
supercomputer. In some
embodiments, processing circuitry may be distributed across multiple separate
processors or
processing units, for example, multiple of the same type of processing units
(e.g., two Intel
Core i7 processors) or multiple different processors (e.g., an Intel Core i5
processor and an
Intel Core i7 processor). In some embodiments, control circuitry 504 executes
instructions
for an application stored in memory (e.g., storage 508). Specifically, control
circuitry 504
may be instructed by the application to perform the functions discussed above
and below.
For example, the application may provide instructions to control circuitry 504
to identify
- 12-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
camera angles for which video data is to be provided to a user device based on
the network or
a likelihood of interest. In some implementations, any action performed by
control circuitry
504 may be based on instructions received from the application.
[0041] In client-server based embodiments, control circuitry 504 may include
communications circuitry suitable for communicating with a content application
server or
other networks or servers. The instructions for carrying out the above-
mentioned
functionality may be stored on the content application server. Communications
circuitry may
include a cable modem, an integrated services digital network (ISDN) modem, a
digital
subscriber line (DSL) modem, a telephone modem, Ethernet card, or a wireless
modem for
communications with other equipment, or any other suitable communications
circuitry. Such
communications may involve the Internet or any other suitable communications
networks or
paths (which is described in more detail in connection with FIG. 6). In
addition,
communications circuitry may include circuitry that enables peer-to-peer
communication of
devices, or communication of devices in locations remote from each other
(described in more
detail below).
[0042] Memory may be an electronic storage device provided as storage 508 that
is part of
control circuitry 504. As referred to herein, the phrase "electronic storage
device" or "storage
device" should be understood to mean any device for storing electronic data,
computer
software, or firmware, such as random-access memory, read-only memory, hard
drives,
optical drives, digital video disc (DVD) recorders, compact disc (CD)
recorders, BLU-RAY
disc (BD) recorders, BLU-RAY 3D disc recorders, digital video recorders (DVR,
sometimes
called a personal video recorder, or PVR), solid state devices, quantum
storage devices,
gaming consoles, gaming media, or any other suitable fixed or removable
storage devices,
and/or any combination of the same. Storage 508 may be used to store various
types of
content described herein, including, for example, the video data corresponding
to the multiple
angles of a content item that is streamed to a device and historical data for
determining which
camera angle is likely to be of interest. Nonvolatile memory may also be used
(e.g., to
launch a boot-up routine and other instructions). Cloud-based storage,
described in relation
to FIG. 6, may be used to supplement storage 508 or instead of storage 508. In
some
embodiments, a database is accessible at the cloud-based storage, where the
database stores a
content item that is streamed to a device, sets of video frames that are
identified as suitable
replacements for corresponding video frames, metadata containing mappings of
time
segments to sets of video frames, and identifiers for scene start and end
points. Nonvolatile
memory may also be used (e.g., to launch a boot-up routine and other
instructions).

[0043] Control circuitry 504 may include video generating circuitry and tuning
circuitry,
such as one or more analog tuners, one or more MPEG-2 decoders or other
digital decoding
circuitry, high-definition tuners, or any other suitable tuning or video
circuits or combinations
of such circuits. Encoding circuitry (e.g., for converting over-the-air,
analog, or digital
signals to MPEG signals for storage) may also be provided. Control circuitry
504 may also
include scaler circuitry for upconverting and downconverting content into the
preferred
output format of the user equipment 500. Circuitry 504 may also include
digital-to-analog
converter circuitry and analog-to-digital converter circuitry for converting
between digital
and analog signals. The tuning and encoding circuitry may be used by the
device to receive
and to display, to play, or to record content. The tuning and encoding
circuitry may also be
used to receive content data. The circuitry described herein, including for
example, the
tuning, video generating, encoding, decoding, encrypting, decrypting, scaler,
and
analog/digital circuitry, may be implemented using software running on one or
more general
purpose or specialized processors. Multiple tuners may be provided to handle
simultaneous
tuning functions (e.g., watch and record functions, picture-in-picture (PIP)
functions, or
multiple-tuner recording). If storage 508 is provided as a separate device
from user
equipment 500, the tuning and encoding circuitry (including multiple tuners)
may be
associated with storage 508.
[0044] A user may send instructions to control circuitry 504 using user input
interface 510.
User input interface 510 may be any suitable user interface, such as a remote
control, mouse,
trackball, keypad, keyboard, touchscreen, touchpad, stylus input, joystick,
voice recognition
interface, or other user input interfaces. Display 512 may be provided as a
stand-alone device
or integrated with other elements of each one of device 500 and user equipment
system 501.
For example, display 512 may be a touchscreen or touch-sensitive display. In
such
circumstances, user input interface 510 may be integrated with or combined
with display 512.
Display 512 may be one or more of a monitor, a television, a liquid crystal
display (LCD) for
a mobile device, amorphous silicon display, low temperature poly silicon
display, electronic
ink display, electrophoretic display, active matrix display, electro-wetting
display,
electrofluidic display, cathode ray tube display, light-emitting diode
display,
electroluminescent display, plasma display panel, high-performance addressing
display, thin-
film transistor display, organic light-emitting diode display, surface-
conduction electron-
emitter display (SED), laser television, carbon nanotubes, quantum dot
display,
interferometric modulator display, or any other suitable equipment for
displaying visual
images. In some embodiments, display 512 may be HDTV-capable. In some
embodiments,
- 14-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
display 512 may be a 3D display, and the interactive application and any
suitable content may
be displayed in 3D. A video card or graphics card may generate the output to
the display
512. The video card may offer various functions such as accelerated rendering
of 3D scenes
and 2D graphics, MPEG-2/MPEG-4 decoding, TV output, or the ability to connect
multiple
monitors. The video card may be any processing circuitry described above in
relation to
control circuitry 504. The video card may be integrated with the control
circuitry 504.
Speakers 514 may be provided as integrated with other elements of each one of
device 500
and user equipment system 501 or may be stand-alone units. The audio component
of videos
and other content displayed on display 512 may be played through speakers 514.
In some
.. embodiments, the audio may be distributed to a receiver (not shown), which
processes and
outputs the audio via speakers 514.
[0045] The content application may be implemented using any suitable
architecture. For
example, it may be a stand-alone application wholly-implemented on each one of
device 500
and user equipment system 501. In such an approach, instructions of the
application are
stored locally (e.g., in storage 508), and data for use by the application is
downloaded on a
periodic basis (e.g., from an out-of-band feed, from an Internet resource, or
using another
suitable approach). Control circuitry 504 may retrieve instructions of the
application from
storage 508 and process the instructions to generate any of the displays
discussed herein.
Based on the processed instructions, control circuitry 504 may determine what
action to
perform when input is received from input interface 510.
[0046] In some embodiments, the application is a client-server based
application. Data for
use by a thick or thin client implemented on each one of device 500 and user
equipment
system 501 is retrieved on-demand by issuing requests to a server remote to
each one of
device 500 and user equipment system 501. In one example of a client-server
based content
.. application, control circuitry 504 runs a web browser that interprets web
pages provided by a
remote server. For example, the remote server may store the instructions for
the application
in a storage device. The remote server may process the stored instructions
using circuitry
(e.g., control circuitry 504) and generate the displays discussed above and
below. The client
device may receive the displays generated by the remote server and may display
the content
of the displays locally on equipment device 500. This way, the processing of
the instructions
is performed remotely by the server while the resulting displays are provided
locally on
equipment device 500.
[0047] In some embodiments, the content application is downloaded and
interpreted or
otherwise run by an interpreter or virtual machine (run by control circuitry
504). In some
- 15-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
embodiments, the content application may be encoded in the ETV Binary
Interchange Format
(EBIF), received by control circuitry 504 as part of a suitable feed, and
interpreted by a user
agent running on control circuitry 504. For example, the content application
may be an EBIF
application. In some embodiments, the content application may be defined by a
series of
JAVA-based files that are received and run by a local virtual machine or other
suitable
middleware executed by control circuitry 504. In some of such embodiments
(e.g., those
employing MPEG-2 or other digital media encoding schemes), the content
application may
be, for example, encoded and transmitted in an MPEG-2 object carousel with the
MPEG
audio and video packets of a program.
[0048] Each one of device 410 and user equipment system 501 of FIG. 5 may be
implemented in system 600 of FIG. 6 as user television equipment 602, user
computer
equipment 604, wireless user communications device 606, or any other type of
user
equipment suitable for accessing content, such as a non-portable gaming
machine. For
simplicity, these devices may be referred to herein collectively as user
equipment or devices
and may be substantially similar to devices described above. Devices, on which
an
application may be implemented, may function as a standalone device or may be
part of a
network of devices. Various network configurations of devices may be
implemented and are
discussed in more detail below.
[0049] A device utilizing at least some of the system features described above
in
connection with FIG. 5 may not be classified solely as user television
equipment 602, user
computer equipment 604, or a wireless user communications device 606. For
example, user
television equipment 602 may, like some user computer equipment 604, be
Internet-enabled
allowing for access to Internet content, while user computer equipment 604
may, like some
television equipment 602, include a tuner allowing for access to television
programming.
The application may have the same layout on various different types of user
equipment or
may be tailored to the display capabilities of the user equipment. For
example, on user
computer equipment 604, the content application may be provided as a web site
accessed by a
web browser. In another example, the content application may be scaled down
for wireless
user communications devices 606.
[0050] In system 600, there is typically more than one of each type of device
but only one
of each is shown in FIG. 6 to avoid overcomplicating the drawing. In addition,
each user
may utilize more than one type of device and also more than one of each type
of device.
[0051] In some embodiments, a device (e.g., user television equipment 602,
user computer
equipment 604, wireless user communications device 606) may be referred to as
a "second
- 16-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
device." For example, a second device may provide an interface for adjusting
settings and
display preferences of the first device. In some embodiments, the second
device is
configured for interacting with other second devices or for interacting with a
social network.
The second screen device may be located in the same room as the first device,
a different
room from the first device but in the same house or building, or in a
different building from
the first device.
[0052] The user may also set various settings to maintain consistent
application settings
across in-home devices and remote devices. For example, if a user enables
dynamic
identification of camera angles to be provided for display on their personal
computer at their
office, this feature would also be enabled on the user's in-home devices
(e.g., user television
equipment and user computer equipment) as well as the user's mobile devices,
if desired.
Therefore, changes made on one device may change the content experienced on
another
device, regardless of whether they are the same or a different type of device.
In addition, the
changes made may be based on settings input by a user, as well as user
activity monitored by
the content application. In addition, two devices may work together to provide
functionality
for the user. For example, the first device identifying which camera angle for
which to
provide video data may further instruct the second device to display the video
data of the
identified camera angle.
[0053] The devices may be coupled to communications network 614. Namely, user
television equipment 602, user computer equipment 604, and wireless user
communications
device 606 are coupled to communications network 614 via communications paths
608, 610,
and 612, respectively. Communications network 614 may be one or more networks
including
the Internet, a mobile phone network, mobile voice or data network (e.g., a 4G
or LTE
network), cable network, public switched telephone network, or other types of
communications network or combinations of communications networks. Paths 608,
610, and
612 may separately or together include one or more communications paths, such
as, a satellite
path, a fiber-optic path, a cable path, a path that supports Internet
communications (e.g.,
IPTV), free-space connections (e.g., for broadcast or other wireless signals),
or any other
suitable wired or wireless communications path or combination of such paths.
Path 612 is
drawn with dotted lines to indicate that in the exemplary embodiment shown in
FIG. 6 it is a
wireless path and paths 608 and 610 are drawn as solid lines to indicate they
are wired paths
(although these paths may be wireless paths, if desired). Communications with
the devices
may be provided by one or more of these communications paths but are shown as
a single
path in FIG. 6 to avoid overcomplicating the drawing.
- 17-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
[0054] Although communications paths are not drawn between devices, these
devices may
communicate directly with each other via communications paths, such as those
described
above in connection with paths 608, 610, and 612, as well as other short-range
point-to-point
communications paths, such as USB cables, IEEE 1394 cables, wireless paths
(e.g.,
Bluetooth, infrared, or IEEE 602-11x), or other short-range communication via
wired or
wireless paths. BLUETOOTH is a certification mark owned by Bluetooth SIG, INC.
The
devices may also communicate with each other directly through an indirect path
via
communications network 614.
[0055] System 600 includes content source 616 and content data source 618
coupled to
communications network 614 via communications paths 620 and 622, respectively.
Paths
620 and 622 may include any of the communications paths described above in
connection
with paths 608, 610, and 612. Communications with the content source 616 and
content data
source 618 may be exchanged over one or more communications paths but are
shown as a
single path in FIG. 6 to avoid overcomplicating the drawing. In addition,
there may be more
than one of each of content source 616 and content data source 618, but only
one of each is
shown in FIG. 6 to avoid overcomplicating the drawing. If desired, content
source 616 and
content data source 618 may be integrated as one source device. Although
communications
between sources 616 and 618 with devices 602, 604, and 606 are shown as
through
communications network 614, in some embodiments, sources 616 and 618 may
communicate
directly with devices 602, 604, and 606 via communications paths (not shown)
such as those
described above in connection with paths 608, 610, and 612.
[0056] Content source 616 may include one or more types of content
distribution
equipment including a television distribution facility, cable system headend,
satellite
distribution facility, programming sources (e.g., television broadcasters),
intermediate
distribution facilities and/or servers, Internet providers, on-demand content
servers, and other
content providers. Content source 616 may be the originator of content (e.g.,
a television
broadcaster or a Webcast provider) or may not be the originator of content
(e.g., an on-
demand content provider or an Internet provider of content of broadcast
programs for
downloading). Content source 616 may include cable sources, satellite
providers, on-demand
providers, Internet providers, over-the-top content providers, or other
providers of content.
Content source 616 may also include a remote content server used to store
different types of
content (including video content selected by a user), in a location remote
from any of the
devices. Content source 616 may include at least 2 sources for content that
provide content
for the content application to provide on the user devices (e.g., user devices
102 and 202).

Systems and methods for remote storage of content and providing remotely
stored content to
user equipment are discussed in greater detail in connection with Ellis et
al., U.S. Patent No.
7,761,892, issued July 20, 2010, which is hereby incorporated by reference
herein in its
entirety.
[0057] Content data source 618 may provide data related to the content.
Content data may
be provided to the devices using any suitable approach. In some embodiments,
the content
application may be a stand-alone interactive television program guide that
receives program
guide data via a data feed (e.g., a continuous feed or trickle feed). Program
schedule data and
other content data may be provided to the user equipment on a television
channel sideband,
using an in-band digital signal, using an out-of-band digital signal, or by
any other suitable
data transmission technique. Program schedule data and other content data may
be provided
to user equipment on multiple analog or digital television channels.
[0058] In some embodiments, content data from content data source 618 may be
provided
to user's equipment using a client-server approach. For example, a user
equipment device
may pull content data from a server, or a server may push content data to a
user equipment
device. In some embodiments, a content application client residing on the
user's equipment
may initiate sessions with source 618 to obtain content data when needed,
e.g., when the
content data is out of date or when the device requests the data. Content data
may be
provided to the user equipment with any suitable frequency (e.g.,
continuously, daily, a user-
specified period of time, a system-specified period of time, or in response to
a request from
user equipment). Content data source 618 may provide devices 602, 604, and 606
the
application itself or software updates for the application.
[0059] In some embodiments, the content data may include viewer data. For
example, the
viewer data may include current and/or historical user activity information
(e.g., what content
the user typically watches, what times of day the user watches content,
whether the user
interacts with a social network, at what times the user interacts with a
social network to post
information, what types of content the user typically watches (e.g., pay TV or
free TV),
mood, or brain activity information). The content data may also include
subscription data.
For example, the subscription data may identify to which sources or services a
given user
subscribes and/or to which sources or services the given user has previously
subscribed but
later terminated access (e.g., whether the user subscribes to premium
channels, whether the
user has added a premium level of services, whether the user has increased
Internet speed).
In some embodiments, the viewer data and/or the subscription data may identify
patterns of a
given user for a period of less or more than one year. The content data may
include a model

PCT/US2020/052289
(e.g., a survivor model) used for generating a score that indicates a
likelihood a given user
will terminate access to a service/source. For example, the application may
monitor a user's
engagement with content to generate a value or score that indicates a
likelihood of whether
the given user will terminate access to a particular service or source. In
particular, a higher
score may indicate a higher level of confidence that the user will terminate
access to a
particular service or source. Based on the score, the application may generate
promotions
that entice the user to keep the particular service or source indicated by the
score as one to
which the user will likely terminate access. The content data may include
metadata files
pertaining to the content or content segments (e.g., characteristics of
content portions, content
segments related to a current portion of content based on a characteristic).
The content data
may also include user profiles used to determine likelihoods of the user
navigating away from
or to a content portion or segment. For example, content data may include
information
characterizing content such as the director, producer, actors, activities
occurring during the
content, locations the content was created, any description of the content
context or the
content production, or any suitable combination thereof.
[0060] Applications may be, for example, stand-alone applications implemented
on
devices. For example, the application may be implemented as software or a set
of executable
instructions which may be stored in storage 508 and executed by control
circuitry 504 of each
one of device 500 and user equipment system 501. In some embodiments,
applications may
be client-server applications where only a client application resides on the
device, and server
application resides on a remote server. For example, applications may be
implemented
partially as a client application on control circuitry 504 of each one of
device 500 and user
equipment system 501 and partially on a remote server as a server application
(e.g., content
data source 618) running on control circuitry of the remote server. When
executed by control
circuitry of the remote server (such as content data source 618), the
application may instruct
the control circuitry to generate the content displays and transmit the
generated displays to
the devices. The server application may instruct the control circuitry of the
content data
source 618 to transmit data for storage on the device. The client application
may instruct
control circuitry of the receiving user equipment to generate the content
displays.
[0061] Content and/or content data delivered to devices 602, 604, and 606 may
be OTT
content. OTT content delivery allows Internet-enabled user devices, including
any device
described above, to receive content that is transferred over the Internet,
including any content
described above, in addition to content received over cable or satellite
connections. OTT
content is delivered via an Internet connection provided by an Internet
service provider (ISP),
- 20-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
but a third party distributes the content. The ISP may not be responsible for
the viewing
abilities, copyrights, or redistribution of the content, and may only transfer
IP packets
provided by the OTT content provider. Examples of OTT content providers
include
YOUTUBE, NETFLIX, and HULU, which provide audio and video via IP packets.
YouTube is a trademark owned by Google Inc., Nedlix is a trademark owned by
Nedlix Inc.,
and Hulu is a trademark owned by Hulu, LLC. OTT content providers may
additionally or
alternatively provide content data described above.
[0062] Content output system 600 is intended to illustrate a number of
approaches, or
network configurations, by which devices and sources of content and content
data may
communicate with each other for the purpose of identifying camera angles that
capture a
content item for which video data is to be provided for. The embodiments
described herein
may be applied in any one or a subset of these approaches, or in a system
employing other
approaches for delivering content. The following four approaches provide
specific
illustrations of the generalized example of FIG. 6.
[0063] In one approach, devices may communicate with each other within a home
network.
Devices may communicate with each other directly via short-range point-to-
point
communication schemes described above, via indirect paths through a hub or
other similar
device provided on a home network, or via communications network 614. Each of
the
multiple individuals in a single home may operate different devices on the
home network. As
a result, it may be desirable for various content application information or
settings to be
communicated between the different devices. For example, it may be desirable
for users to
maintain consistent application settings on different devices within a home
network, as
described in greater detail in Ellis et al., U.S. Patent Publication No.
2005/0261827, filed
July 11, 2005. Different types of devices in a home network may also
communicate with
each other to transmit content. For example, a user may use content navigation
button 120 on
one device while the content is transmitted to a second device to be generated
for display.
[0064] In a second approach, users may have multiple types of user equipment
by which
they access content. For example, some users may have home networks that are
accessed by
in-home and mobile devices. Users may control in-home devices via an
application
implemented on a remote device. For example, users may access an online
application on a
website via a personal computer at their office, or a mobile device such as a
PDA or web-
enabled mobile telephone. The user may set various settings (e.g., recordings,
reminders,
content segment buffering enablement, or other settings) on the online content
application to
control the user's in-home equipment. The online application may control the
user's
- 21 -

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
equipment directly, or by communicating with an application on the user's in-
home
equipment. Various systems and methods for devices communicating, where the
devices are
in locations remote from each other, is discussed in, for example, Ellis et
al., U.S. Patent No.
8,046,801, issued October 25, 2011, which is hereby incorporated by reference
herein in its
entirety.
[0065] In a third approach, users of devices inside and outside a home may use
their
application to communicate directly with content source 616 to access content.
Specifically,
within a home, users of user television equipment 602 and user computer
equipment 604 may
access the application to navigate among and locate desirable content. Users
may also access
the application outside of the home using wireless user communications devices
606 to
navigate among and locate desirable content.
[0066] In a fourth approach, devices may operate in a cloud computing
environment to
access cloud services. In a cloud computing environment, various types of
computing
services for content sharing, storage or distribution (e.g., video sharing
sites or social
networking sites) are provided by a collection of network-accessible computing
and storage
resources, referred to as "the cloud." For example, the cloud may include a
collection of
server computing devices, which may be located centrally or at distributed
locations, that
provide cloud-based services to various types of users and devices connected
via a network
such as the Internet via communications network 614. These cloud resources may
include
one or more content sources 616 and one or more content data sources 618. In
addition or in
the alternative, the remote computing sites may include other devices, such as
user television
equipment 602, user computer equipment 604, and wireless user communications
device 606.
For example, the other devices may provide access to a stored copy of a video
or a streamed
video. In such embodiments, devices may operate in a peer-to-peer manner
without
communicating with a central server.
[0067] The cloud provides access to services, such as content storage, content
sharing, or
social networking services, among other examples, as well as access to any
content described
above, for devices. Services may be provided in the cloud through cloud
computing service
providers, or through other providers of online services. For example, the
cloud-based
services may include a content storage service, a content sharing site, a
social networking
site, or other services via which user-sourced content is distributed for
viewing by others on
connected devices. These cloud-based services may allow a device to store
content to the
cloud and to receive content from the cloud rather than storing content
locally and accessing
locally-stored content.

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
[0068] Cloud resources may be accessed by a device using, for example, a web
browser, an
application, a desktop application, a mobile application, and/or any
combination of access
applications of the same. The device may be a cloud client that relies on
cloud computing for
application delivery, or the device may have some functionality without access
to cloud
resources. For example, some applications running on the device may be cloud
applications,
i.e., applications delivered as a service over the Internet, while other
applications may be
stored and run on the device. In some embodiments, a user device may receive
content from
multiple cloud resources simultaneously. For example, a user device may stream
audio from
one cloud resource while downloading content from a second cloud resource. Or
a user
device may download content from multiple cloud resources for more efficient
downloading.
In some embodiments, devices may use cloud resources for processing operations
such as the
processing operations performed by processing circuitry described in relation
to FIG. 5.
[0069] Any one or more of device 500 and user equipment system 501 of FIG. 5
and user
television equipment 602, user computer equipment 604, and wireless user
communications
device 606 of FIG. 6 may be used to identify camera angles for which to
provide video data
using at least one of a network parameter or likelihood of interest. For
example, the content
applications, associated with user devices, of the present disclosure may
provide video data
for popular camera angles (e.g., using historical data to determine camera
angles that have
been viewed by a threshold number of users or for a threshold amount of time).
Further
details of the present disclosure are discussed below in connection with the
flowcharts of
FIGS. 7-9. It should be noted that the steps of processes 700, 800, and 900 of
FIGS. 7-9,
respectively, may be performed by control circuitry 504 of FIG. 5. Control
circuitry 504 may
be part of a device having a display 512 (e.g., a device that may have any or
all of the
functionality of user television equipment 602, user computer equipment 604,
and/or wireless
communications device 606 of FIG. 6 such as user device 410 of FIG. 4), part
of a remote
server separated from the user equipment by way of a communications network
(e.g.,
communications network 614 of FIG. 6), or distributed over a combination of
both.
[0070] FIG. 7 depicts a flowchart of illustrative process 700 for determining
one or more
camera angles to provide based on a network parameter, in accordance with at
least some
embodiments of the disclosure.
[0071] At step 702, the content application determines a network parameter for
a network
over which a content item is provided to a device. For example, the content
application
determines a network bandwidth, a number of users on the network, a maximum
download
speed, any suitable performance or usage metric of a network, or any
combination thereof.
- 23 -

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
[0072] At step 704, the content application determines whether the network
parameter
supports transmission of the video data for one or more camera angles over the
network. The
content application identifies, in some implementations, one or more of the
plurality of
camera angles for which to provide video data using the network based at least
in part on the
network parameter. For example, the content application determines to provide
video data
for 10 camera angles whose sum of download speeds does not exceed the maximum
download speed of the network.
[0073] Although not depicted in process 700, the content application may
further base the
identification of camera angles for which video data is to be provided on a
predetermined
distribution of camera angles within 360 degrees. For example, camera angles
are provided
in distribution such that there is an approximately even distribution of
camera angles between
the end points of angles available. A content application may divide the total
range of angles
available by a number of camera angles to be provided or any suitable number
for providing
an even distribution of camera angles. If a content item is associated with
camera angles
from 0 to 90 degrees, an approximately even distribution of 2 camera angles
may be at 30 and
60 (e.g., dividing 90 by the number of camera angles plus 1). Similarly, an
approximately
even distribution of 3 camera angles may be at 23, 46, and 69. In some
embodiments, prior
to proceeding to step 706, the content application identifies one or more
camera angles for
which to provide video data further based on a user indication of a camera
angle. For
example, the content application identifies camera angles based on a change in
orientation of
the device such as a tilt of the device (e.g., tilting by N degrees to select
a camera angle N
degrees away) or a shake of the device (e.g., to select the next angle
available in a clockwise
sequence). In some embodiments, the content application provides a
notification to the
device, indicating that the network will not adequately support the video data
corresponding
to the camera angle as requested through a user indication. For example, a
user may tilt the
phone to an angle that requires a download speed higher than the network can
support. In
response to determining that the network will not adequately support the video
data for that
angle, the content application may provide a notification on a user interface
of the device
alerting the user to the failed attempt to switch angles.
[0074] At step 706, the content application causes the video data for the one
or more
camera angles of step 704 to be provided to a device. For example, the content
application
communicates one or more video data addresses (e.g., video data addresses 320-
329) of
respective camera angles to the device. The content application additionally
provides, in
- 24-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
some implementations, authorization to the device to access the video data
addresses. The
video data addresses may be hosted by a content source such as content source
430.
[0075] FIG. 8 depicts a flowchart of an illustrative process for identifying a
camera angle
that is likely to be of interest, in accordance with at least some embodiments
of the
disclosure.
[0076] At step 802, the content application makes video data for camera angles
available to
a device. As described in step 706 of process 700, the content application, in
some
embodiments, makes video data available by providing video data addresses
(e.g., addresses
320-329) hosting the video data of the respective camera angles.
[0077] At step 804, the content application determines whether one or more of
the camera
angles are likely to be of interest. The content application dynamically
identifies camera
angles that are likely to be of interest by comparing camera angles to one
another (i.e.,
determining some are likely to be of interest relative to others). For
example, the content
application determines that the camera angle having the largest depiction of a
cricket ball
(e.g., the depiction of the ball at one camera angle occupies a larger
percentage of the video
frame dimension than the depictions of the ball at other camera angles) is
likely to be of
interest relative to other camera angles. The content application determines,
in some
embodiments, that a view of an event being depicted is unobstructed. For
example, the
content application uses image processing to identify objects and determines a
mapping of
what objects should be depicted at which angles. The content application may
identify a
cricket ball is present in one angle, that the view is unobstructed in that
angle, and that the
view of the cricket ball is obstructed in another angle because although the
ball should be
depicted in the other angle, image processing does not recognize any ball in
the other angle.
[0078] Although not depicted in process 800, the content application may rank
the camera
angles according to the relative likelihoods of interest among camera angles
(e.g., before
proceeding to step 804). For example, the content application ranks camera
angles with
unobstructed views of a ball higher than camera angles with obstructed views.
The content
application uses, in some embodiments, historical data to rank camera angles.
For example,
the content application ranks camera angles at any time of the content item's
consumption
according to the number of devices to which the video data for those camera
angles was
provided or the number of requests received by devices to consume the video
data at the
respective camera angles. Based on the determined ranking, the content
application may
provide visual indicators for display at the device that are indicative of the
determined
ranking of the camera angles. For example, the content application provides a
visual
- 25 -

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
indicator for a top percentile (e.g., the top 10%) of ranked camera angles
such that the user
sees an icon on the user interface of the device that is brighter than, a
different color than, a
larger size than, or distinguished in any suitable visual manner from, an icon
associated with
a camera angle outside of the top percentile.
[0079] In some embodiments, camera angles are pre-curated such that the
dynamic
identification occurs prior to the video data for the camera angles being made
available to the
device. For example, video data may be stored at a content source and the
content
application may determine, using any of the dynamic identification methods
described herein,
which of the camera angles for which video data is stored to be provided over
time to a user
device (e.g., provide camera angle 45 degrees at the start of the content item
and switch to
camera angle 120 degrees after 25 seconds).
[0080] At step 806, the content application causes the video data for the one
or more of the
camera angles to be provided to the device. For example, the content
application
automatically provides, for display, the video data associated with the camera
angles that are
determined to be the most likely to be of interest relative to other angles.
The content
application may, to provide the video data for the identified camera angles,
authorize the
device to access video data addresses associated with the identified camera
angles while
disabling authorization to access other video data addresses.
[0081] FIG. 9 depicts a flowchart of illustrative process 900 for determining
camera angles
to provide, based on both a network parameter and a likelihood of interest, in
accordance
with at least some embodiments of the disclosure. The steps of processes 700
and 800 may
be steps within process 900.
[0082] At step 902, the content application makes video data for camera angles
available to
a device. The content application may provide video data addresses of
respective camera
angles to a device. Making video data available includes, in some embodiments,
allowing the
user to request video data of all available camera angles without transmitting
the video data
to the device. For example, a user interface on a display of the device may
show that 50
camera angles are made available by the content application for consumption,
but video data
is provided only for a subset of the camera angles based on the subsequent
steps 904-914.
[0083] At step 904, the content application determines network parameters for
a network.
Network parameters include network bandwidth, number of devices on the
network, a
maximum download speed, any suitable performance metric of a network, any
suitable usage
metric of a network, or any combination thereof For example, the content
application
determines a network bandwidth of 200 Mbps and that there are 4 devices on the
network.
- 26-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
From this, the content application may use a hypothetical allocation of 50
Mbps/user of the
network bandwidth when determining which camera angles are supported by the
network in
step 906.
[0084] At step 906, the content application determines whether the network
parameters
support video data for a camera angle. Although multiple network parameters
are used in
process 900, one or more network parameters may be used to determine
capability of the
network to support a camera angle (e.g., in step 908) or used for the weighted
average in step
912. The content application evaluates, in some embodiments, a camera angle
based on a
combination of the network bandwidth and the number of devices on the network.
For
example, a camera angle at 300 degrees (e.g., camera angle corresponding to
video data
address 320) requires a bit rate of 5 Mbps.
[0085] At step 908, the content application determines whether the capability
of the
network to support a camera angle is determined for each camera angle. If the
content
application has not determined the capabilities of the network to support all
camera angles
available from step 902, the content application returns to step 906 to
determine whether the
network parameters support video data for another camera angle. For example,
the content
application may return to step 906 to determine that a camera angle at 340
degrees (e.g.,
camera angle corresponding to video data address 321) requires a bit rate of
45 Mbps due to
4k formatting. Once the content application has determined the capabilities of
the network to
.. support each camera angle (e.g., for each angle, whether the network can or
cannot support
that angle), the content application proceeds to step 910.
[0086] At step 910, the content application determines the likelihood of
interest for one or
more of the camera angles. For example, the content application uses image
processing on
what is depicted through the camera angle at 300 degrees and through the
camera angle at 55
degrees. The content application may identify the objects depicted and the
relative sizes of
those objects in one camera angle compared to the other. For example, a
cricket ball is
depicted at both 300 degrees and 55 degrees, but the size of the cricket ball
depicted at the
300-degree camera angle is larger than that of the same ball depicted at the
55-degree camera
angle. The content application, accordingly, determines that the camera angle
at 300 degrees
is more likely to be of interest compared to the camera angle at 55 degrees.
[0087] Although not depicted, the content application may calculate various
permutations
of groups of camera angles supported by the network. For example, a
combination of camera
angles at 300 and 55 degrees and a combination of camera angles at 300, 55,
and 145 degrees
are both supported by the network.
- 27-

CA 03144482 2021-12-17
WO 2021/061827
PCT/US2020/052289
[0088] At step 912, the content application determines, based on a weighted
average of
network parameters and likelihoods of interest, camera angles to be provided
to a device. For
example, the content application applies weights to network parameters and
interest
parameters (e.g., historical data, real-time statistics, relative sizes of
objects depicted in
camera angles, and unobstructed views). Based on preferences in a user
profile, the content
application weighs, in some embodiments, unobstructed views higher than real-
time statistics
of the camera angle that is most accessed. The content application may
determine that
camera angles at 300 degrees and 55 degrees are to be provided rather than
camera angles at
300 degrees and 145 degrees. Although both combinations may be determined to
be
supported by the network, the camera angle at 55 degrees may have an
unobstructed view
while the camera angle at 145 degrees does not, and the weight for the
parameter for
unobstructed views is large (e.g., the user profile indicates that he heavily
prioritizes
unobstructed views).
[0089] At step 914, the content application causes the video data for the one
or more of the
camera angles to be provided to the device. The content application may
authorize the device
to access video data addresses associated with the identified camera angles
while disabling
authorization to access other video data addresses. The display may be an
automated switch
between camera angles that are determined to be of most interest. For example,
although
video data for camera angles at both 300 degrees and 55 degrees are provided,
the camera
angle at 55 degrees may be the more interesting of the two camera angles. In
response to
determining the camera angle associated with the highest likelihood of
interest, the content
application, in some embodiments, provides the video data associated with the
camera angle
at 55 degrees to be displayed automatically on the device.
[0090] The above-described embodiments of the present disclosure are presented
for
purposes of illustration and not of limitation, and the present disclosure is
limited only by the
claims that follow. Furthermore, it should be noted that the features and
limitations described
in any one embodiment may be applied to any other embodiment herein, and
flowcharts or

in a
suitable manner, done in different orders, or done in parallel. In addition,
the systems and
methods described herein may be performed in real-time. It should also be
noted, the
systems and/or methods described above may be applied to, or used in
accordance with, other
