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 ~
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.
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 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 Graphics (PNG) file is a compressed graphic image file. Here, it is obvious that an audio file such as an au file or an aiff file can be attached to an image file instead of the PNG file in another language.
FIG. 3 is an outline diagram of the volume space of the embodiment of the DVD
300 of the present invention.
With reference to FIG. 3, the volume space of the DVD 300 includes a control information section that includes the control information on volume and the file, a DVD-video data section that includes a relevant video title data, and a DVD-interactive data section that contains data that supports the interactive mode.
io The DVD-video data section contains the files VIDEO_TS.IFO, VTS_01_0.IFO, VTS_01_O.VOB, VTS_01_1.VOB, ... that are recorded in DVD_TS, which is the DVD
video directory of FIG. 2. The DVD-interactive data section contains the files DVD_ENAV.IFO, A.HTM (KOR), A.HTM (JPN), A.HTM (ENG), W.PNG, X.PNG, and Y.PNG, which are recorded in DVD_ENAV, the DVD interactive directory of FIG.
2.
FIG. 4 shows the structure of the file DVD_ENAV.IFO explained in FIGS. 2 and 3.
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 codes. 0x0412, 0x0411 and 0x0409 are hexadecimal values and indicate Korean, Japanese, and English, respectively.
In a language mapping table, which contains the language mapping information, caption language codes are mapped to language codes for mapping to relevant HTML
documents which are referred to for extracting the markup documents that contain text information to be displayed in the languages corresponding to the caption language codes. To be more specific, the captions are displayed in Korean, Japanese, English, 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.
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.
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 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 Graphics (PNG) file is a compressed graphic image file. Here, it is obvious that an audio file such as an au file or an aiff file can be attached to an image file instead of the PNG file in another language.
FIG. 3 is an outline diagram of the volume space of the embodiment of the DVD
300 of the present invention.
With reference to FIG. 3, the volume space of the DVD 300 includes a control information section that includes the control information on volume and the file, a DVD-video data section that includes a relevant video title data, and a DVD-interactive data section that contains data that supports the interactive mode.
io The DVD-video data section contains the files VIDEO_TS.IFO, VTS_01_0.IFO, VTS_01_O.VOB, VTS_01_1.VOB, ... that are recorded in DVD_TS, which is the DVD
video directory of FIG. 2. The DVD-interactive data section contains the files DVD_ENAV.IFO, A.HTM (KOR), A.HTM (JPN), A.HTM (ENG), W.PNG, X.PNG, and Y.PNG, which are recorded in DVD_ENAV, the DVD interactive directory of FIG.
2.
FIG. 4 shows the structure of the file DVD_ENAV.IFO explained in FIGS. 2 and 3.
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 codes. 0x0412, 0x0411 and 0x0409 are hexadecimal values and indicate Korean, Japanese, and English, respectively.
In a language mapping table, which contains the language mapping information, caption language codes are mapped to language codes for mapping to relevant HTML
documents which are referred to for extracting the markup documents that contain text information to be displayed in the languages corresponding to the caption language codes. To be more specific, the captions are displayed in Korean, Japanese, English, 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.
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.
