DETAILED DESCRIPTION
To better describe the objectives, technical solutions, and advantages of the
present
invention clearer, the embodiments of the present invention are described in
details below with
reference to the enclosed drawings.
4
CA 02927516 2016-04-14
Referring now to FIG.1, therein is shown a structural schematic of a team
voice instrument in
embodiments of the present invention. The team voice instrument can include at
least a terminal
110 and a server 120.
The terminal 110 can be an electronic device, such as a computer, a smart
phone, a tablet, or
e-book reader. The electronic device can install an application client of the
team voice instrument,
or a browser. The electronic device can access a web client of the team voice
instrument via the
browser. The terminal 110 can be categorized by users, such as teacher
terminals used by teachers
and student terminals used by students. The teacher is a user teaching lecture
files. The teacher
can upload the lecture files to the server 120. The server 120 can process the
lecture files and send
the processed lecture files to the teacher terminals and the student
terminals. The students are
users learning the lecture files. The students can receive and display the
processed lecture files
from the server 120. In this embodiment of the present invention, the teacher
terminals and the
student terminals are in the same teaching channel.
The server 120 can be connected to the terminal 110 via wired or wireless
network. The
server 120 can be one server, multiple servers, or a cloud computation center.
In other words, the
server 120 can be implemented by one server or a combination of multiple
servers, wherein each
of the multiple servers can provide same or different functions, such as a
register and login server,
a client portrait storage server, a channel information and configuration
storage server, or a picture
and video storage server, etc. The server 120 can be implemented by the cloud
computation center,
wherein the cloud computation center is a virtual computation platform with a
cluster of servers.
Referring now to FIG 2, therein is shown a flow chart of a file sharing method
in one
embodiment of the present invention. The embodiment of the present invention
describes the file
sharing method applied to the implementing environment shown in FIG 1 as an
example. The file
sharing method includes following steps.
Step 201, the terminal sends a file to the server, wherein the file can
include a file generated
by the terminal, or transmitted to the terminal from other equipment. The
embodiment of the
present invention does not restrict sources of the file. The terminal can send
the file to the server
via wired or wireless network.
Step 202, the server receives the file from the terminal, wherein the server
can receive the
file from the terminal via wired or wireless network, which corresponds to the
manner of sending
5
CA 02927516 2016-04-14
file of the terminal.
Step 203, the server generates a shared address set of the file. When the file
sent from the
terminal includes multiple pages, the server can decompose the file to
multiple file pages and
generate one of shared addresses for each of the file pages such that the
terminal can download
one of the file pages in accordance with each of the shared addresses. Or, the
terminal can
generate one shared address for a plurality of the file pages, such that the
terminal can download
the plurality of the file pages in accordance with the shared address, to
reduce the interaction
between the terminal and the server, resulting in improvement of the
downloading efficiency.
Preferably, the server can group the shared addresses as the shared address
set and send the
shared address set to the terminal, to save communication resources comparing
with sending each
of the shared addresses to the terminal individually.
Step 204, the server feedbacks the shared address set to the terminal. The
server can send the
shared address set to the terminal, to avoid the problems in prior art of the
terminal uploading the
file pages to and receiving the shared addresses from the server individually
and repeatedly,
resulting in saving communication resources and reduction of the cost.
Specifically, the server can feedback the shared address set to the terminal
via wired or
wireless network.
Step 205, the terminal receives the shared address set feedback from the
server. Specifically,
the terminal can receive the shared address set from the server via wired or
wireless network.
Step 206, the terminal shares the shared address set with other terminals. The
terminal can
share entire or a portion of the shared addresses of the shared address set
with the other terminals.
The other terminals can download the file from the server in accordance with
the shared
addresses.
In summary, the file sharing method provided by the embodiment of the present
invention
includes, receiving a file from a terminal, generating a shared address set of
the file, feedbacking
the shared address set to the terminal, the terminal sharing shared addresses
of the shared address
set with other terminals. The method of the embodiment of the present
invention resolves the
problems in the prior art of increased interactions between the server and the
terminal caused by
uploading the decomposed file pages to the server individually and repeatedly,
when the file has
multiple pages, resulting in saving communication resources and reduction of
the cost.
Referring now to FIG. 3A, therein is shown a flow chart of a file sharing
method in another
6
CA 02927516 2016-04-14
one embodiment of the present invention. The embodiment of the present
invention describes the
file sharing method applied to the implementing environment shown in FIG 1.
The difference
between the current embodiment and the embodiment shown in FIG 2 is that, a
server can convert
the file format of a received file, and share the converted file. The file
sharing method can
comprises following steps.
Step 301, a terminal sends a file to the server. The file can be generated by
the terminal. Or,
when the file format is not commonly supported by the terminal, the
predetermined application
supporting the file format is not commonly used, or the installation of the
predetermined
application is complicated. The terminal can fetch the file from other
equipment to avoid the
installing and calling of the predetermined application. The embodiment of the
present invention
does not restrict file sources.
The terminal can sent the file to the server, wherein the file format of the
file can be the file
format when the file is created, or the file format after the file is
converted. The embodiment of
the present invention does not restrict the file format. For example, the
terminal can send the
server a PPT file. The PPT file can be created by the OFFICE, or converted
from files with other
file formats by the OFFICE.
In general, the file can include multiple pages. To reduce the interaction
between the terminal
and the server, the terminal can send a plurality of the file pages altogether
to the server. Further,
the terminal can send a plurality of the file altogether to the server.
Specifically, the terminal can
send the file to the server via wired or wireless network.
Step 302, the server receives the file from the terminal. The server can
receive the file from
the terminal via wired or wireless network.
Step 303, the server can convert the file format.
Because the server is pre-installed a predetermined file format conversion
application, the
server can call the predetermined file format conversion application after
receives the file. The
server can convert the file format of the file with the predetermined file
format conversion
application and generate a converted file.
Specifially, the file format conversion can include decomposing the file into
a plurality of the
file pages, and converting each of the file pages to one of the converted file
pages with a
predetermined file format.
If the file includes a plurality of pages, the server can decompose the file
into a plurality of
7
CA 02927516 2016-04-14
the file pages, and convert the file format of each of the decomposed file
pages to the
predetermined file format. The predetermined file format can be a default or a
specified file
format, such as an image format or a text format. The converted file pages can
refer to the file
pages after the file format conversion.
Typically, the server can enable a system mode. In the system mode, the
predetermined file
format conversion application can only convert one file at a time, resulting
in a lower file
conversion efficiency. The system mode may be system user accounts. Therefore,
if there are at
least two files, the file format conversion may include:
enabling at least two system modes in parallel; and
converting the files in turn in each of the system modes with the
predetermined file format
conversion application pre-installed in the server.
For example, when the server installs WINDOWS system, the WINDOWS system can
set up
at least two user accounts. Since each of the user accounts can call the
OFFICE to convert one
PPT file, parallel logging on to the at least two user accounts can convert at
least two PPT files in
parallel, resulting in improvement of the conversion efficiency.
The version of the predetermined file format conversion application installed
on the terminal
may be various. Different version of the predetermined file format conversion
application may
convert the file differently. For example, a lower version of the
predetermined file format
conversion application may convert the file with a lower conversion quality.
Therefore, the server
can install the latest version of the predetermined file format conversion
application and convert
all of the files from terminals with the latest version to avoid lower
conversion quality and
conversion inconsistency among the different terminals.
Further, the server can configure conversion parameters of the predetermined
file format
conversion application, to further improve the file conversion quality.
Specifically, before
enabling at least two system modes in parallel, the server can configure
conversion parameters for
a predetermined file format conversion application. Then, converting the files
in turn via the
predetermined file format conversion application installed in the server
includes converting the
files in turn via the predetermined file format conversion application
configured with the
conversion parameters.
For example, OFFICE can configure a picture resolution when a PPT file is
converted to a
picture. The server can configure the picture resolution in accordance with
the conversion
CA 02927516 2016-04-14
requirement.
Step 304, the server generates the shared address set. When the file sent by
the terminal
includes multiple pages, the server can generate one of the shared addresses
for each of the
converted file pages, so the terminal can download one of the converted file
page in accordance
with the one of the shared addresses. Or the server can generate one shared
address for multiple
converted file pages, so the terminal can download multiple converted file
pages in accordance
with the shared address, to reduce the interaction between the terminal and
the server, resulting in
improvement of the downloading efficiency. Typically, each of the shared
addresses of the shared
address set can correspond to one or multiple converted file pages.
Preferably, the server can combine the generated shared addresses of the file
pages as the
shared address set and send the shared address set to the terminal, to save
the communication
resources than sending the shared addresses to the terminal one at a time.
Step 305, the server can feedback the shared address set to the terminal. The
server can send
the shared address set to the terminal, to avoid the waste of communication
resources in the prior
art cause by the terminal uploading the decomposed file pages to and receiving
the shared
addresses from the server individually and repeatedly, resulting in saving of
communication
resources and reduction of the cost.
Specifically, the server can feedback the shared address set to the terminal
via a wired or
wireless network.
Step 306, the terminal can receive the shared address set from the server.
Specifically,
corresponding to how the server feedbacks the shared address set, the terminal
can receive the
shared address set from the server via a wired or wireless network.
Further, after receives the shared address set from the server, the terminal
can download the
file pages corresponding to the shared addresses of the shared address set.
If the terminal needs to acquire the converted file, after receiving the
shared address set, the
terminal can acquire the converted file from the server in accordance with the
shared address set.
For example, the terminal can acquire the file pages in accordance with the
shared addresses of
the shared address set in sequence. Or, the terminal may acquire a plurality
of the file pages in
parallel in accordance with a plurality of the shared addresses of the shared
address set.
Step 307, the terminal shares the shared addresses of the shared address set
with other
terminals. The terminal can share entire or a portion of the shared addresses
of the shared address
9
CA 02927516 2016-04-14
set with the other terminals. The other terminals can acquire the converted
files from the server in
accordance with the shared addresses.
Preferably, the terminal may confirm that the file pages corresponding to the
shared
addresses of the shared address set are acquired successfully, before the
terminal shares the shared
addresses with the other terminals, in order to improve file sharing success
rate in other terminals.
In particular, the terminal sharing the shared addresses of the shared
addresses set with other
terminals can include:
sending the shared addresses of the shared addresses set to a predetermined
equipment, and
the predetermined equipment broadcasting the shared addresses of the shared
addresses set to the
other terminals.
In the embodiment of the present invention, the terminal may share or
broadcast the shared
addresses of the shared addresses set to the other terminals directly. Or, the
terminal can send the
shared addresses of the shared addresses set to the predetermined equipment,
and the
predetermined equipment can broadcast the shared addresses of the shared
addresses set to the
other terminals. Wherein, before send or broadcast the shared addresses, the
terminal or the
predetermined equipment may need to determine the other terminals receiving
the shared
addresses. For example, the other terminals may be terminals connected to the
terminal, or may be
other terminals in the predetermined equipment corresponding to the terminal.
The number of the
other terminals is at least one .
Further, the predetermined equipment can cache the shared addresses of the
shared address
set, in order to send the cached shared addresses to subsequently joined other
terminals. Wherein
the subsequently joined other terminals can be at least one.
Further, the terminal may store the shared address set, in order to acquire
the converted file
in accordance with the stored shared address set subsequently.
Additionally, in the embodiment of the present invention, the server can be
broken down into
a front end server, a conversion server, and a sharing server. The front end
server is used to
communicate with the sharing server and the terminal. The conversion server is
used to
commnicate with the front end server. The sharing server is used to commnicate
with the front end
server and the terminal. Alternatively, in the embodiment of the present
invention, the server can
also be broken down into the front end server and the conversion server, while
the sharing server
is a third-party equipment interacting with the server. Since the conversion
server can interact
CA 02927516 2016-04-14
with the front end server via predetermined accounts, the safety of the
converted file can be
guarantied.
Referring now to FIG 3B, therein is shown a schematic of a first application
of the file
sharing method in one embodiment of the present invention. In FIG. 3B, a
server is for example
divided into a front end server, a conversion server, and a sharing server.
The front-end server may
receive a file sent from a terminal, and forward the file to the conversion
server. The conversion
server converts the file format of the file, and sends the converted files to
the front end server. The
front end server can upload the converted file to the sharing server, and
receive a shared address
set feedback from the sharing server. The front end server can feedback the
shared address set to
the terminal.
In summary, the file sharing method provided by the embodiment of the present
invention
can include, receiving a file from a terminal, generating a shared address set
of the file,
feedbacking the shared address set to the terminal, sharing the shared
addresses of the shared
address set with other terminals. The method of the embodiment of the present
invention solves
the problems in the prior art of increased interactions between the server and
the terminal caused
by uploading the decomposed file pages to the server individually and
repeatedly when the file
has multiple pages, resulting in saving communication resources and reduction
of the cost.
Additionally, by enabling at least two system modes in parallel, the files can
be converted in
sequence in each of the system modes by a predetermined file format conversion
application
pre-installed on the server, and the predetermined file format conversion
application can be
invoked in parallel in the server to convert the files. The method of the
embodiment of the present
invention solves a low conversion efficiency problem caused by individual
conversion of the files
with the predetermined file format conversion application, resulting in
improvement of the
conversion efficiency.
Referring now to FIG 3C, therein is shown a schematic diagram of a second
application of a
file sharing method. The file sharing method provided in the embodiment of the
present invention
can be applied in online education. In FIG 3C, teachers can prepare a PPT
lecture file on the
terminal, wherein the PPT lecture file can include at least one page. The
teachers send the PPT
lecture file to the server via the terminal. The server can convert each of
the PPT lecture file pages
to one of images, and generate an image set of all the images. The server can
store each of the
images of the image set, and assigns a URL to one or several images. The
server can combine the
11
CA 02927516 2016-04-14
URLs of the images into a URL set, and forward the URL set to the terminal.
After receives the URL set via the terminal, the teachers can send or
broadcast the URL set to
other terminals connected to the terminal.
Alternatively, the teachers can send the URL set to a predetermined equipment,
and the
predetermined equipment can broadcast the URL set to students. Further, to
diversify the course
contents, the predetermined equipment may provide multiple teaching channels
corresponding to
subjects. Each of the teaching channels can be accessed by a teacher and
several students. After
receives the URL set, the predetermined equipment can determine the teaching
channel accessed
by the teacher, and broadcast the URL set to the students who access the said
teaching channel.
The teacher through the terminal and the students through the other terminal
/, 2..., and n, send
image requests with the URL to the sharing server, and download the images in
accordance with
the URL. Alternatively, in order to improve the success rate of sharing
images, the teacher can
share the URLs after acquiring the images. For example, the teacher can send
the requests with
the image URL to the sharing server and download the images in accordance with
the URLs from
a sharing server, before send the URLs to the predetermined equipment. After
receiving the URLs,
the predetermined equipment can determine the teaching channel accessed by the
teacher, and
broadcast the URL to the students who access the said teaching channel.
Through other terminals
/, 2, to n, the students can send image requests with URL to the sharing
server, and acquire the
images from the sharing server corresponding to the URLs. The teacher can
teach the course
based on the images, after teacher and students get all the images.
Further, the predetermined equipment can store the broadcasted URL set. If the
predetermined equipment detects that subsequently joined students accessing
the said teaching
channel, the predetermined equipment can send the URL set to the subsequently
joined student
terminals. The subsequently joined student terminals can acquire the converted
images in
accordance with the received URL set.
Referring now to FIG 3D, therein is shown an application interface diagram of
the file
sharing method in the embodiments of the present invention. In HG 3D, the
teacher teaches a
mathematics course. The teacher and the students access a teaching channel
8619. The total
number of persons accessing the teaching channel is 364. The teacher's lecture
content is shown
in an exercise area 310 on the left of the screen. From top to bottom on the
right of the screen is a
teacher information display area 311, a floor control display area 312, a
discussion & question
12
CA 02927516 2016-04-14
display area 313, and an input display area 314. Wherein, the teacher
information includes a
teacher's picture, a nickname, and number of followers. After the students
enter texts in an input
box in the input display area 314 and click a SEND button to the right of the
input box, the
students entered texts can be displayed in the discussion & question display
area 313.
Referring now to FIG. 4, therein is shown a flow chart of a file sharing
method in another one
embodiment of the present invention. The flow chart in FIG. 4 describes the
file sharing method
applied to implementing environment shown in FIG I. The difference between
this embodiment
and the embodiment shown in FIG 2 is that, the server can convert the received
lecture file format,
and share the converted lecture file. The file sharing method can include
following steps.
Step 401, the teacher terminal can send the lecture file to the server,
wherein the lecture file
can include at least one lecture file page.
The lecture file sent to the server from the teacher terminal can be the
lecture file generated
by the teacher terminal, or acquired from other equipment. The embodiment of
the present
invention does not restrict file sources. Wherein acquiring the file from
other equipment can avoid
installation of the application supporting the lecture file format on the
teacher terminal, and save
memory spaces thereof.
In general, one lecture file can include at least one file pages. To reduce
the interaction
between the teacher terminal and the server, the teacher terminal can send
entire lecture file to the
server. Further, the teacher terminal can send the server a plurality of the
lecture files altogether.
.. The teacher terminal can send the server the lecture files via a wired or
wireless network.
Step 402, the server receives the lecture file from the teacher terminal. The
server can receive
the lecture file from the teacher terminal via a wired or wireless network.
Step 403, the server can convert each of the lecture file pages to one of
converted lecture file
pages with a predetermined file format.
Because the server is pre-installed a predetermined file format conversion
application
converting the lecture file, the server can call the predetermined file format
conversion application
after receives the lecture file. The server then can decompose the lecture
file into a plurality of
lecture file pages, and convert each of the lecture file pages to one of
converted lecture file pages
with the predetermined file format. Wherein the predetermined file format can
be default or
specified, such as, an image format or a text format. The converted lecture
file pages refer to the
file pages of the decomposed lecture file page converted to the predetermined
file format.
13
CA 02927516 2016-04-14
Typically, the server can enable a system mode. In the system mode, the
predetermined file
format conversion application can only convert one lecture file at a time,
resulting in a lower
lecture file conversion efficiency. Wherein, the system mode may be system
user accounts.
Therefore, if there are at least two lecture files, the lecture file format
conversion may include:
enabling at least two system modes in parallel, and
converting each of the lecture files in sequence in each of the system modes
with the
predetermined file format conversion application pre-installed on the server.
For example, when WINDOWS system is installed in the server, the WINDOWS
system can
set up at least two user accounts. Since each of the user accounts can call
OFFICE to convert one
PPT lecture file, parallel logging on to the at least two user accounts can
convert at least two PPT
lecture files in parallel, resulting in improvement of the conversion
efficiency.
The version of the predetermined file format conversion application installed
on the teacher
terminal may be viarious. Different version of the predetermined file format
conversion
application may convert the lecture file differently. For example, a lower
version of the
predetermined file format conversion application may convert the lecture file
with a lower
conversion quality. Therefore, the server can install the latest version of
the predetermined file
format conversion application and convert the lecture file with the latest
version to avoid lower
conversion quality and conversion inconsistency resulting from conversion of
the lecture file by
different teacher terminals.
Further, the server can configure conversion parameters of the predetermined
file format
conversion application, to further improve the lecture file conversion
quality. Specifically, before
enabling at least two system modes in parallel, the conversion parameters for
the predetermined
file format conversion application are configured. Then, converting the
lecture files in sequence
via the predetermined file format conversion application installed on the
server comprises
converting the lecture files in sequence through the predetermined file format
conversion
application after configuration.
For example, OFFICE can configure an image resolution when converting a PPT
lecture file
to an image. The server can configure the image resolution in accordance with
the conversion

increased interactions
between the server and the teacher terminal caused by uploading decomposed
lecture file pages to
the server individually and repeatedly when the lecture file has multiple
pages, resulting in saving
communication resources and reduction of the cost. Additionally, by enabling
at least two system
modes in parallel, the server can convert the lecture files in sequence in one
of the system
modes with a predetermined file format conversion application pre-installed on
the server, and the
predetermined file format conversion application can be invoked in parallel to
convert files. The
method of the embodiment of the present invention solves a low conversion
efficiency problem
caused by individual conversion of the lecture files with the predetermined
file format conversion
application, resulting in improvement of the conversion efficiency.
Referring now to FIG 5, therein is shown a flow chart of a file sharing method
in another one
embodiment of the present invention. The flow chart in FIG 5 describes the
file sharing method
applied to the implementing envrionment shown in FIG 1. The difference between
the current
embodiment and the embodiment shown in FIG. 4 is that, the server can be
broken down into a
front end server, a conversion server, and a sharing server. The file sharing
method can include
following steps.
Step 501, the teacher terminal send the lecture file to the front end server,
wherein the lecture
file can includes at least one lecture file page.
The lecture file sent to the server from the teacher terminal can be the
lecture file generated
by the teacher terminal, or acquired from other equipment. The embodiment of
the present
invention does not restrict to file sources. Wherein acquiring the file from
other equipment can
avoid installation of the application supporting the lecture file format on
the teacher terminal, and
save memory spaces of the teacher terminal.
In general, the lecture file can include at least one lecture file pages. To
reduce the interaction
between the teacher terminal and the front end server, the teacher terminal
can send entire lecture
file to the front end server. Further, the teacher terminal can send the front
end server a plurality of
the lecture files altogether. The teacher terminal can send the front end
server the lecture files via
a wired or wireless network.
17
CA 02927516 2016-04-14
Step 502, the front end server receives the lecture file from the teacher
terminal.
Corresponding to the manner of sending the lecture file by the teacher
terminal, the front end
server can receive the lecture file from the teacher terminal via a wired or
wireless network.
Step 503, the front end server can send the lecture file to the conversion
server.
Wherein, the conversion server can convert the format of each of lecture file
pages in the
lecture file.
Step 504, the conversion server receives the lecture file from the front end
server, and
converts each lecture file page of the lecture file to the converted lecture
file page with the
predetermined file format.
Because the conversion server is pre-installed a predetermined file format
conversion
application, the conversion server can call the predetermined file format
conversion application
after receives the lecture file. The lecture file can be decomposed into
lecture file pages by the
predetermined file format conversion application, and each of the lecture file
pages can be
converted to the converted lecture file pages with a predetermined file
format. The predetermined
file format can be a default or a specified file format, such as an image
format or a text format.
The converted lecture file pages can refer to the decomposed lecture file
pages subjected to the
predetermined file format conversion.
Typically, the conversion server can enable a system mode. In one system mode,
the
predetermined file format conversion application can only convert one lecture
file at a time,
resulting in a lower lecture file conversion efficiency. The system mode may
be system user
accounts. Therefore, if there are at least two lecture files, the lecture file
format conversion may
include: enabling at least two system modes in parallel, and converting each
of the lecture files in
each of the system modes with the predetermined file format conversion
application pre-installed
on the conversion server.
For example, when the conversion server installs WINDOWS system, at least two
user
accounts can be set up in the WINDOWS system. Since each of the user accounts
can call
OFFICE to convert one PPT lecture file, parallel logging on to the at least
two user accounts can
convert at least two PPT lecture files in parallel, resulting in improvement
of the conversion
efficiency.
The version of the predetermined file format conversion application installed
on the
teacher terminal may be viarious. Different version of the predetermined file
format conversion
18
CA 02927516 2016-04-14
application may convert the lecture file differently. For example, a lower
version of the
predetermined file format conversion application may convert the lecture file
with a lower
conversion quality. Therefore, the conversion server can install the latest
version of the
predetermined file format conversion application and convert the lecture file
with the latest
version to avoid lower conversion quality and conversion inconsistency
resulting from convertion
of lecture files by different teacher terminals.
Further, the conversion server can configure conversion parameters of the
predetermined
file format conversion application, to further improve the lecture file
conversion quality.
Specifically, before enabling at least two system modes in parallel, the
conversion server can
configure the conversion parameters of the predetermined file format
conversion application.
Then converting the lecture files via the predetermined file format conversion
application installed
in the conversion server including converting the lecture files via the
predetermined file format
conversion application after configuration.
For example, OFFICE can configure an image resolution when converting a PPT
lecture file
to an image. The conversion server can configure the image resolution in
accordance with the
conversion requirement.
Step 505, the conversion server sends the converted lecture file pages with
the predetermined
file format to the front end server.
The conversion server can convert each of the lecture file pages to one of the
converted
lecture file pages with the predetermined file format, and send the converted
lecture file pages to
the front end server.
Step 506, the front end server receives the converted lecture file pages with
the
predetermined file format.
Step 507, the front end server sends the converted lecture file pages with the
predetermined
file format to the sharing server.
Wherein, the sharing server can share the converted lecture file pages with
the predetermined
file format.
Step 508, the sharing server shares each of the converted lecture file pages
with the
predetermined file format, generates a shared address set of the converted
lecture file pages.
Wherein the shared address set can include at least one shared address, and
each shared address
corresponds to one of the converted lecture file pages.
19
CA 02927516 2016-04-14
The sharing server can generate a shared address for each of the pages of the
converted
lecture file. The teacher terminal can acquire a single converted lecture file
page in accordance
with one the shared address. Or the sharing server can generate a shared
address for at least two
converted lecture file pages. The teacher terminal can acquire at least two
converted lecture file
pages in accordance with a single shared address, to reduce the interaction
between the teacher
terminal and the sharing server, resulting in improvement of the downloading
efficiency.
Step 509, the sharing server can send the shared address set to the front end
server.
After generates the shared addresses of the lecture file pages, the sharing
server can combine
the shared addresses of all lecture file pages into the shared address set and
send the shared
address set to the front end server, to save the communication resources
required from sending the
shared addresses individually and repeatedly.
Step 510, the front end server receives the shared address set.
Step 511, the front end server feedback the shared address set to the teacher
terminal.
The front end server can send the shared address set to the teacher terminal,
to save the
communication resources required from sending the shared addresses
individually and repeatedly.
Specifically, the front end server can feedback the shared address set via a
wired or wireless
network.
Step 512, the teacher terminal receives the shared address set from the front
end server.
Specifically, corresponding to the manner of sending the shared address set by
the front end
server, the teacher terminal can feedback the shared address set via a wired
or wireless network.
Step 513, the teacher terminal can acquire the lecture file page corresponding
to each shared
addresses of the shared address set.
If the teacher terminal needs to acquire the converted lecture file, the
teacher terminal can
acquire the converted lecture file from the sharing server in accordance with
the shared address
set received from the sharing server. For example, the teacher terminal can
acquire the lecture file
pages in accordance with the shared addresses of the shared address set in
sequence. Or, the
teacher terminal may acquire a plurality of lecture file pages in parallel in
accordance with a
