INFORMATION STORAGE MEDIUM CONTAINING INFORMATION FOR PROVIDING
MULTI-LANGUAGE MARKUP DOCUMENT, APPARATUS
AND METHOD FOR REPRODUCING THEREOF
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an interactive information storage medium, a
reproducing apparatus, and a reproducing method, and more particularly, to an
interactive information storage medium containing multi-language markup
document
io support information which is provided together with a reproduced data
stream displayed
in a display window defined by a markup document, and an apparatus and a
method for
reproducing the information storage medium.
2. Description of the Related Art
A proposed interactive DVD medium in current market(e.g., PC Friendly DVD
disc) can be reproduced in an interactive mode based on PC(Personal Computer).
The
interactive DVD medium contains markup language documents and AV Data. . AV
data recorded on the interactive DVD medium is reproduced as an AV data stream
and
displayed in two ways: in a video mode or an interactive mode. In the video
mode, AV
data is displayed in the same way as it is displayed on regular DVD players
while in the
iriteractive mode, AV data is displayed together with an HTML document in a
display
window defined by the HTML document. If the interactive mode is selected by a
user,
a web browser installed in a PC(Personal Computer) displays the HTML document
recorded on the interactive DVD medium. The AV data to related to the HTML
document is reproduced and displayed in the display window defined by the HTML
document.
For example, in the case of a movie whose content is the AV data, a video is
played in the display window defined by the HTML document, and in the
remaining part
of the display screen, a variety of supplementary information including
scripts, stories,
and photos of actors and actresses can be displayed. The supplementary
information
may be displayed in synchronization with a title (AV data). For example, when
an actor
is on stage, an HTML document containing his brief history is invoked and
displayed
together with his video.
An existing DVD-video standard defines sub-picture data that provides a
~


CA 02405661 2002-09-30

multi-language captioning together with the reproduced title. Therefore, the
user can
enjoy captions in a desired language when watching a program.
However, the proposed interactive DVD is disadvantageous in that it allows
text-based
supplementary information to be displayed in only one language, together with
the AV
data in the interactive mode. That is, the proposed interactive DVD does not
have the
capability to present the supplementary information displayed through the HTML
document in multiple languages. Therefore, a user cannot understand text-based
information displayed through the HTML document in a language that is foreign
to the
user. As a result, the interactive mode provided by the interactive DVD is not
attractive
io to the user.

DETAILED DESCRIPTION OF THE INVENTION
The present invention now will be described more fully with reference to the
accompanying drawings, in which preferred embodiments of the invention are
shown.
FA markup documenti , in the specification, means not only a markup document
itself

but also a web resource that includes files inserted into or linked with the
markup
document. An HTML document means a document which is prepared in a mark-up
language such as XML or SGML and can be interpreted and displayed by the web
browser.
FIG. 1 is a block diagram of a reproducing apparatus according to a preferred
embodiment of the present invention.
With reference to FIG. 1, the reproducing apparatus decodes AV data recorded
on an embodiment of a DVD 300 of the present invention and reproduces the AV
data
as an AV data stream. Then, the reproducing apparatus displays the AV data in
a
3o display window defined by a markup document in an interactive mode and
includes a
reader 1, a buffer memory 2, a cache memory 3, an AV decoder 4, a presentation
engine 5, and an AV blender 6.
The presentation engine 5 supports the interactive mode.
6


CA 02405661 2002-09-30

In terms of software, the presentation engine 5 includes application programs
such as a markup document viewer (ex. web browser), a program interpretation
engine,
and a plug-in that interfaces through Application Program Interface (API) with
the
operating system of the reproducing apparatus. With the API, which is a
special
pre-defined method, the presentation engine 5 can send a request to the OS and
other
application programs. The program interpretation engine includes a JavaScript
or a
Java interpretation engine. The plug-in enables various markup documents to be
displayed.
In terms of hardware, the presentation engine 5 is set to have a default value
on
io the markup document language information of reproducing apparatus, that is,
the
information about the language of the markup document that is displayed when
the
interactive mode is selected. For example, the reproducing apparatus to be
released
in English-speaking nations has markup document language information that
commands the selection of the markup document having text information in
English. It
is preferable that the markup document language information varies depending
on
where the reproducing device is marketed or which languages are dominant. If a
user
changes a default value on the markup document language information, the
markup
document is displayed in the new selected language or relevant language.
The reader 1 reads the HTML document or the AV data from the DVD 300. The
2o embodiment of the DVD 300 of the present invention contains a data packet
where
sub-picture data and AV data are multiplexed and packaged. Therefore, reading
the
AV data means reading the sub-picture together with the AV data. However, if
the
user does not select the caption display function, the sub-picture data is
discarded
without being reproduced. The buffer memory 2 buffers the AV data read by the
reader 1. The cache memory 3 caches the markup document read by the reader 1.
The AV decoder 4 decodes the AV data buffered in the buffer memory 2 and
outputs
the AV data stream. The presentation engine 5 interprets the read markup
document
and identifies the location of the display window. Then, the AV blender 6
displays
markup document outputted by the presentation engine 5 and the AV data stream
outputted by the AV decoder 4 in the display window.
FIG. 2 shows the structure of files in the embodiment of the DVD 300 of the
present invention.
The DVD 300 contains multiple markup documents having the same meaning
7


CA 02405661 2002-09-30

content in different languages so that text information included in the markup
documents can be displayed in multiple languages. That is, the DVD 300
according to
the present invention includes multiple markup documents which contain exactly
the
same meaning text information in multiple languages, respectively.
With reference to FIG. 2, a root directory includes directories VIDEO_TS and
DVD_ENAV. The VIDEO_TS is a DVD video directory containing the AV data, and
DVD_ENAV is a DVD interactive directory for recording the data including the
markup
document that supports the interactive mode.
The VIDEO_TS directory includes VIDEO_TS.IFO, VTS_01_0.IF0,
io VTS_01_O.VOB, and VTS_01_1.VOB, .... VIDEO_TS.IFO contains the reproducing
control information on the entire video title and the language information
designated as
a default value of the video title. In VTS_01_0.lFO, the reproducing control
information
on the first video title set is recorded. VTS 01 O.VOB and VTS 01 1.V0B are
Video
Object Set (VOBS) that make up the video title set. Each VOB includes video
data,
ts audio data, and sub-picture data. The sub-picture data is designed to
display the
captions of the movie. More detailed configuration information is included in
the
DVD-Video Standard DVD-Video for Read Only Memory Disc 1Ø
The DVD_ENAV directory includes the file DVD_ENAV.IFO which contains the
reproducing control information on the entire title information in interactive
mode. To be
20 more specific, DVD_ENAV.IFO includes the definition and configuration of
the relevant
directory, the number of titles included, basic information, the language used
for the title,
information on captions and fonts, markup document display information such as
resolution and color, and copyright information. DVD_ENAV.IFO further includes
multi-language markup document information according to the present
embodiment.
25 The multi-language markup document information will be described in detail
later. In
addition, multi-language markup document directories, including KOR, JPN, and
ENG,
are prepared to support languages of the markup document according to the
embodiment. KOR, JPN, and ENG indicate a Korean Language directory, a Japanese
Language directory, and an English Language directory, respectively. Each
30 multi-language markup document directory includes the file A.HTM which has
the same
meaning text information in the associated language, and files W.PNG, X.PNG,
and
Y.PNG which are displayed together with A.HTM. Because W.PNG, X. PNG, and
Y.PNG are the same image, they may have the same file name. A Portable Network

With reference to FIG. 4, DVD_ENAV.IFO includes the multi-language markup
document information according to the present invention. The multi-language
markup
document information contains information on the kind of languages that can be
2o displayed, language mapping information, and information on the directory
by
respective language.
FIG. 5 is a detailed structure diagram of an embodiment of multi-language
markup document information according to the present invention. With reference
to
FIG. 5, the displayable language information included in the multi-language
markup
document information includes information on the number of displayable
languages, the
codes of the displayable languages and whether the languages can be changed
during
reproduction.
The codes of the displayable languages can be indicated as ISO-639 language

or Chinese. The markup document displayed with the captions is displayed in
Korean,
Japanese, or English. Therefore, if the user selects Korean, Japanese, or
English for
the captions, the markup document is displayed in the corresponding language,
Korean,
Japanese, or English. However, if the user selects Chinese for caption
display, the
markup document is displayed in English. The number of displayable languages
can
vary. Even when the markup document is displayed without interworking with the
captioning, the language mapping table can be referred to for extracting the
markup
io document. For example, if the language of the reproducing apparatus is set
as
Chinese (ZH), the presentation engine 5 displays the markup document prepared
in
English (EN-US) by referring to the language mapping table. The information on
changeability of markup document language indicates whether the user can
change the
language during reproduction of the AV data. 0 indicates that the language
cannot be
changed while 1 indicates that the language can be changed.
The language directory information includes the path names of the
multi-language markup document directories containing markup documents
corresponding to the displayable language codes, respectively and the file
name of the
HTML document designated as a start document file.
FIG. 6 shows examples of the markup documents retrieved and displayed with
reference to the multi-language markup document information of FIG. 5.
FIGS. 6A through 6C show markup documents displayed when Korean captions,
Japanese captions, and English or Chinese captions are selected, respectively.
In case
of Chinese caption, the captions language is different from the text
information is
displayed in the markup document.. That is, since a multi-language markup
document
is supported in the interactive mode, the present invention can display the
markup
document containing the text information prepared in the language mapped to
the
captioning selected by the user or the language selected by the user. If the
user
changes the Korean captions into Japanese captions while a video title is
reproduced in
the interactive mode, the markup document displayed together is changed from
FIG. 6A
to FIG. 6B. That is, the present invention reads and displays A.HTM, the
markup
document, stored in the multi-language markup document directory JPN by
referring to
the language mapping table and the language directory information shown in
FIG. 5.

If the markup document is displayed without interworking with the captioning,
the
markup document containing the text information prepared in the language
selected by
the user is displayed even though the caption is not displayed.
The reproducing method according to the preferred invention is described as
follows.
FIG. 7 is a flowchart explaining a reproduction method according to the
present
invention.
With reference to FIG. 7, if the interactive-DVD 300 according to the present
invention is inserted into the reproducing apparatus, the presentation engine
5 of the
io reproducing apparatus retrieves the language information recorded on
VIDEO_TS.IFO
and identifies if the language designated as a default value of the
reproducing
apparatus exists in step 701. If the language information recorded on
VIDEO_TS.IFO
of the interactive-DVD 300 does not have the language designated as the
default value
of the reproducing apparatus, the presentation engine 5 sets the language
designated
is as a default value of VIDEO TS.IFO or DVD ENAV.IFO of the interactive-DVD
300 as
the default value for the reproduction of the markup document in step 702.
If the language information recorded in ViDEO_TS.IFO of the interactive-DVD
300 has the language designated as the default value of the reproducing
apparatus, the
presentation engine 5 sets the language as the default value for reproduction
of the
20 markup document in step701.
The reader 1 reads the markup document prepared in the designated language
in step 703. For example, if the Korean language is set as the default value
for
reproduction of the markup document, the reader 1 reads A.HTM stored in the
Korean
directory KOR of the multi-language markup document directory. The
presentation
25 engine 5 displays the read markup document iri step 704.
If the user changes the language of the caption in step 705, the presentation
engine 5 identifies whether the languages of the displayed markup documents
can be
changed during reproduction of the AV data by referring to the multi-language
markup
document information described above in step 706. If possible, the
presentation
3o engine retrieves the relevant markup document with reference to the multi-
language
markup document information and the reader 1 reads the retrieved markup
document in
step 707. The presentation engine 5 displays the read markup document in step
708.
If the user completes the reproduction of the reproducing apparatus, the
process ends

in step 709. If the user changes the language of the caption again during the
reproduction, steps 706 through 708 are repeated.
FIG. 8 is a flow chart explaining the reproduction method according to another
embodiment of the present invention.
With reference to FIG. 8, if the interactive-DVD 300 according to the present
invention is inserted into the reproducing apparatus, the presentation engine
5 of the
reproducing apparatus retrieves the language information recorded on VIDEO
TS.IFO
and identifies if the language designated as a default value of the
reproducing
apparatus exists in step 801. If the language information recorded on the
io VIDEO_TS.IFO of the interactive-DVD 300 does not have the language
designated as
the default value of the reproducing device, the presentation engine 5 sets
the language
designated as a default value of VIDEO_TS.IFO or DVD_ENAV.IFO of the
interactive-DVD 300 as the default value for the reproduction of the markup
document in
step 802.
If the language information recorded on the VIDEO_TS.IFO of the
interactive-DVD 300 has the language designated as the default value of the
reproducing device, the presentation engine sets the language as the default
value for
reproduction of the markup document in step801.
The reader 1 reads the markup document prepared in the designated language
in step 803. For example, if the Korean language is set as the default value
for
reproduction of the markup document, the reader 1 reads A.HTM recorded in the
Korean directory KOR of the multi-language markup document directory. The
presentation engine 5 displays the read markup document in step 804.
If the user requests the language of the markup document to be changed in step
805, the presentation engine 5 interprets the multi-language markup document
information and identifies if the languages of the displayed markup documents
can be
changed during reproduction of the AV data in step 806. If the language change
is
possible, the presentation engine displays a menu where the kind of
displayable
languages that can be selected is indicated by referring to the displayable
language
information of the multi-language markup document information in step 807. If
the user
selects the language in step 808, the presentation engine 5 retrieves the
relevant
markup document by referring to the tanguage directory information (and the
language
mapping table) and the reader I reads the retrieved markup document in step
809.

CA 02405661 2002-09-30

The presentation engine 5 displays the read markup document in step 810. If
the user
completes the reproduction of the reproducing apparatus, the process ends in
step 811.
If the user requests the language of the markup document to be changed again
during
the reproduction, steps 806 through 810 are repeated.
As described above, the present invention relates to an information storage
medium that displays the text information included in the markup document in
the
interactive mode in multiple languages and to an apparatus and a method for
reproducing the information storage medium.
