best mode f~r carryinct oat the Inventi~n Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.
Hereinafter, embodiments of the present invention will be described in detail with reference to the appended drawings. In this specification, "interactive data"
refers to data recorded to support an interactive mode and includes a markup document recorded with a markup language and/or a script code, a script code file linked with a markup document or provided separately, a program file, an audio file, an animation file, and an image file as resource files, etc., to be linked with a markup document and displayed with the markup document. That is, the interactive data acts as additional contents being provided with AV data, as well as acts as an application program required to reproduce the AV data in an interactive mode.
FIG. 1 shows a reproduction system according to an embodiment of the present invention. Referring to FIG. 1, the reproduction system comprises an enhanced AV (ENAV) disk 100 as an information storage medium that supports an interactive mode, a reproducing apparatus 200, a display apparatus 300, for example a TV, and a remote controller 400 as a user input device. The remote controller 400 receives a control command input from a user and transfers it to the reproducing apparatus 200. The reproducing apparatus 200 reproduces AV
data recorded on the ENAV disk 100. If the ENAV disk 100 is loaded in a DVD
drive included in the reproducing apparatus 200 and a user selects an interactive mode, the reproducing apparatus 200 reproduces the ENAV disk 100 in the interactive mode and transfers reproduced data to the display apparatus 300. The display apparatus 300 displays both an AV picture corresponding to the reproduced AV data and an interactive picture obtained from an interactive application. "Interactive mode" refers to a method of displaying an AV picture on a display SUBSTITUTE SHEET (RULE 26) window defined in a markup document as an interactive application, that is, a method of displaying both an AV picture and an interactive picture in a manner that the AV picture is embedded in the interactive picture. Here, the AV picture represents a picture in which ~V~-Video data recorded on the EIlIAV disk 100 is reproduced by the reproducing apparatus 200 and is displayed on the display apparatus 300. The interactive picture represents a picture in which an interactive application recorded on the Ei~AV disk 100 is interpreted and executed by the reproducing apparatus 200 and is displayed on the display apparatus 300.
Meanwhile, "video mode" refers to a method of reproducing AV data according to a method defined in a conventional ~V~-Video, that is, a method of displaying only an AV picture obtained by reproducing the corresponding AV data. In this embodiment, the reproducing apparatus 200 supports both the interactive mode and the video mode. Furthermore, the reproducing apparatus 200 can receive AV data and/or interactive data through a network.
The reproducing apparatus 200 has a system parameter table containing system parameters (SPRMs). The system parameter table includes player language information. The reproducing apparatus 200 selects interactive data to be used in the interactive mode with reference to the player language information. The SPRMs may be stored in a memory in the reproducing apparatus 200.
The disk 100 also stores language information indicating a language used in the contents of the stored interactive data. The language information recorded on the disk is substantially the same as the player language information stored in SPRMs, however, the disk language information is different from the player language information in that the disk language information is recorded on the disk 100 and indicates corresponding interactive data.
When the interactive mode is selected, the reproducing apparatus 200 reads language information recorded on the ENAV disk 100, compares the read language information with its own player language information stored as a system parameter, and performs reproduction using interactive data selected according to the compared result.
FIG. 2 is a view explaining the operations of the E~IAV disk 100. Referring to FIG. 2, interactive data corresponding to language information is recorded on the Ef~AV disk 100. That is, interactive data #1 corresponding to language information #1 exists, interactive data #2 SUBSTITUTE SHEET (RULE 26) corresponding to language information #2 exists, ..., interactive data #n corresponding to language information #n exists, wherein n is an integer.
The language information (#1, #2, ..., #n) may be recorded separately from the interactive data (#1, #2, ..., #n) and can be linked with the interactive data (#1, #2, ..., #n), or can be recorded as one part of the interactive data (#1, #2, ..., #n).
If player language information set in the reproducing apparatus 200 is the same as the language information #2, the reproducing apparatus 200 gets the interactive data #2 corresponding to the language information #2 and reproduces corresponding AV
data in an interactive mode. For example, if fihe player language information is "English", the reproducing apparatus 200 uses interactive data corresponding to language information "English" among interactive data recorded on the ENAV disk 100.
FIG. 3 shows a volume space of the ENAV disk 100 according to an embodiment of the present invention. Referring to FIG. 3, the volume space of the ENAV disk 100 includes a Volume and File structure area recording information related to volume and file, a DVD-Video Data area recording AV data or video titles in a DVD-Video format, and an ENAV
file area recording ENAV files supporting an interactive mode.
The DVD-Video data area includes VIDEO TS.IFO containing reproduction control information for all video titles recorded on the ENAV disk 100, VTS 01_O.IFO
containing reproduction control information of a first video title, and VTS 01 O.VOB, VTS
01_1.VOB, ..., as AV data constructing video titles. VTS 01 O.VOB, VTS_01_1.VOB, ... are video titles, that is, video objects. Each VOB contains VOBU in which a navigation pack, a video pack, and an audio pack are packaged. The detailed construction of these data areas are disclosed in "DVD-Video for Read Only Memory Disc 1.0" of a conventional DVD-Video standard.
The ENAV file area stores an ENAV application consisting of a plurality of ENAV files.
That is, the ENAV file area stores as the ENAV files, a startup file to be first read when an interactive mode is selected, a markup document corresponding to a selected video title, etc.
As such, the interactive data is recorded as a plurality of ENAV files. The ENAV files include the following: a markup document; a script code file; a program file;
a style sheet designating a style of a markup document; and an audio file, animation file, an image file, etc.
best mode f~r carryinct oat the Inventi~n Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.
Hereinafter, embodiments of the present invention will be described in detail with reference to the appended drawings. In this specification, "interactive data"
refers to data recorded to support an interactive mode and includes a markup document recorded with a markup language and/or a script code, a script code file linked with a markup document or provided separately, a program file, an audio file, an animation file, and an image file as resource files, etc., to be linked with a markup document and displayed with the markup document. That is, the interactive data acts as additional contents being provided with AV data, as well as acts as an application program required to reproduce the AV data in an interactive mode.
FIG. 1 shows a reproduction system according to an embodiment of the present invention. Referring to FIG. 1, the reproduction system comprises an enhanced AV (ENAV) disk 100 as an information storage medium that supports an interactive mode, a reproducing apparatus 200, a display apparatus 300, for example a TV, and a remote controller 400 as a user input device. The remote controller 400 receives a control command input from a user and transfers it to the reproducing apparatus 200. The reproducing apparatus 200 reproduces AV
data recorded on the ENAV disk 100. If the ENAV disk 100 is loaded in a DVD
drive included in the reproducing apparatus 200 and a user selects an interactive mode, the reproducing apparatus 200 reproduces the ENAV disk 100 in the interactive mode and transfers reproduced data to the display apparatus 300. The display apparatus 300 displays both an AV picture corresponding to the reproduced AV data and an interactive picture obtained from an interactive application. "Interactive mode" refers to a method of displaying an AV picture on a display SUBSTITUTE SHEET (RULE 26) window defined in a markup document as an interactive application, that is, a method of displaying both an AV picture and an interactive picture in a manner that the AV picture is embedded in the interactive picture. Here, the AV picture represents a picture in which ~V~-Video data recorded on the EIlIAV disk 100 is reproduced by the reproducing apparatus 200 and is displayed on the display apparatus 300. The interactive picture represents a picture in which an interactive application recorded on the Ei~AV disk 100 is interpreted and executed by the reproducing apparatus 200 and is displayed on the display apparatus 300.
Meanwhile, "video mode" refers to a method of reproducing AV data according to a method defined in a conventional ~V~-Video, that is, a method of displaying only an AV picture obtained by reproducing the corresponding AV data. In this embodiment, the reproducing apparatus 200 supports both the interactive mode and the video mode. Furthermore, the reproducing apparatus 200 can receive AV data and/or interactive data through a network.
The reproducing apparatus 200 has a system parameter table containing system parameters (SPRMs). The system parameter table includes player language information. The reproducing apparatus 200 selects interactive data to be used in the interactive mode with reference to the player language information. The SPRMs may be stored in a memory in the reproducing apparatus 200.
The disk 100 also stores language information indicating a language used in the contents of the stored interactive data. The language information recorded on the disk is substantially the same as the player language information stored in SPRMs, however, the disk language information is different from the player language information in that the disk language information is recorded on the disk 100 and indicates corresponding interactive data.
When the interactive mode is selected, the reproducing apparatus 200 reads language information recorded on the ENAV disk 100, compares the read language information with its own player language information stored as a system parameter, and performs reproduction using interactive data selected according to the compared result.
FIG. 2 is a view explaining the operations of the E~IAV disk 100. Referring to FIG. 2, interactive data corresponding to language information is recorded on the Ef~AV disk 100. That is, interactive data #1 corresponding to language information #1 exists, interactive data #2 SUBSTITUTE SHEET (RULE 26) corresponding to language information #2 exists, ..., interactive data #n corresponding to language information #n exists, wherein n is an integer.
The language information (#1, #2, ..., #n) may be recorded separately from the interactive data (#1, #2, ..., #n) and can be linked with the interactive data (#1, #2, ..., #n), or can be recorded as one part of the interactive data (#1, #2, ..., #n).
If player language information set in the reproducing apparatus 200 is the same as the language information #2, the reproducing apparatus 200 gets the interactive data #2 corresponding to the language information #2 and reproduces corresponding AV
data in an interactive mode. For example, if fihe player language information is "English", the reproducing apparatus 200 uses interactive data corresponding to language information "English" among interactive data recorded on the ENAV disk 100.
FIG. 3 shows a volume space of the ENAV disk 100 according to an embodiment of the present invention. Referring to FIG. 3, the volume space of the ENAV disk 100 includes a Volume and File structure area recording information related to volume and file, a DVD-Video Data area recording AV data or video titles in a DVD-Video format, and an ENAV
file area recording ENAV files supporting an interactive mode.
The DVD-Video data area includes VIDEO TS.IFO containing reproduction control information for all video titles recorded on the ENAV disk 100, VTS 01_O.IFO
containing reproduction control information of a first video title, and VTS 01 O.VOB, VTS
01_1.VOB, ..., as AV data constructing video titles. VTS 01 O.VOB, VTS_01_1.VOB, ... are video titles, that is, video objects. Each VOB contains VOBU in which a navigation pack, a video pack, and an audio pack are packaged. The detailed construction of these data areas are disclosed in "DVD-Video for Read Only Memory Disc 1.0" of a conventional DVD-Video standard.
The ENAV file area stores an ENAV application consisting of a plurality of ENAV files.
That is, the ENAV file area stores as the ENAV files, a startup file to be first read when an interactive mode is selected, a markup document corresponding to a selected video title, etc.
As such, the interactive data is recorded as a plurality of ENAV files. The ENAV files include the following: a markup document; a script code file; a program file;
a style sheet designating a style of a markup document; and an audio file, animation file, an image file, etc.
SUBSTITUTE SHEET (RULE 26) as resource files to be linked with the markup document and be displayed along with the markup document, as described above.
FIG. 4. is a diagram illustrating a directory structure of the ENAV disk 100 according to an embodiment of the present invention. Referring to FIG. 4., a root directory has a DVD video directory VIDEO TS and an ENAV directory DV~ ENAV storing ENAV data supporting an interactive mode.
The DVD video directory Vl~EO TS stores data described above with reference to FIG. 3, that is, VIDEO TS.IFO, VTS 01 O.IFO, VTS 01 O.VOB, VTS 01 1.VOB, etc.
The ENAV directory DVD_ENAV stores data described above with reference to FIG. 3, that is, a startup file STARTUP.MLS and other ENAV files.
FIG. 5 shows a relationship between the AV data and the ENAV files recorded on the ENAV disk 100 according to an embodiment of the present invention. Referring to FIG. 5, the ENAV disk 100 stores ENAV applications corresponding respectively to AV data, ensuring seamless reproduction. One ENAV application is a set of a plurality of ENAV
files. To ensure seamless reproduction of AV data, an ENAV application corresponding to the AV
data is buffered in advance before the AV data is reproduced in an interactive mode.
Each ENAV application includes one loading information file. The loading information file stores location information of ENAV files that is needed to reproduce the corresponding AV
data in the interactive mode. The location information of ENAV files includes location information for ENAV files to be buffered in advance before the corresponding ENAV application is launched, that is, location information of ENAV files to be preloaded.
Because preloading is performed for each ENAV application, seamless reproduction is ensured for AV data corresponding to each ENAV application. Accordingly, in a view of a user interface, a contents provider makes ENAV applications in a manner that one ENAV application corresponds to 1 piece of video title or 1 chapter of video title in order to ensure seamless reproduction.
Meanwhile, as a contrast to preloading, post-loading is to buffer a desired ENAV file after a corresponding ENAV application is launched. One ENAV application does not always include an ENAV file to be post-loaded. If post-loading is needed, post-load information SUBSTITUTE SHEET (RULE 26) required with post-loading, i.e., location information of ENAV files to be post-loaded, is recorded on the loading information file.
FIG. 6 is a block diagram of the reproduction apparatus 200 according to an embodiment of the present invention. Referring to FIG. 6, the reproduction apparatus 200 includes a reader 1, an AV reproducing engine 2, and an ENAV engine 3.
The reader 1 reads AV data, i.e., DVD-Video data and ENAV files from the DVD
according to a control signal sent from fibs ENAV engine 3. The AV reproducing engine 2 reproduces the AV dafia read by the reader 1. Because the AV data is DVD-Video data, the AV
reproducing engine 2 is implemented by a DVD-Video reproduction engine reproducing DVD-Video data. The AV reproducing engine 2 is communicated with the ENAV engine 3 through an Application Program Interface (API). That is, the AV reproducing engine 2 informs the ENAV
engine 3 of a property indicating a status of the AV reproducing engine 2 in response to a request sent from the ENAV engine 3, and sends a trigger to the ENAV engine 3.
For example, in a case where a corresponding quiz is displayed on an interactive screen simultaneously with a battle scene while a movie, such as "Starwars," is shown in an interactive mode, the trigger informs the ENAV engine 3 of related information when the battle scene is displayed.
The ENAV engine 3 reproduces the ENAV files. Particularly, in the present embodiment, the ENAV engine 3 verifies, interprets, and executes a markup document as an ENAV file in order that the DVD-Video data recorded on the DVD 100 can be reproduced in the interactive mode. Also, the ENAV engine 3 blends and outputs a reproduced DVD-Video stream and an interpreted markup document. Accordingly, a picture in which an AV
picture is embedded in an interactive picture is displayed on the display apparatus 300.
Meanwhile, the ENAV engine 3 can include various plug-ins. Plug-ins are used to open various formats of files included in the markup document or linked with the markup document. For example, to reproduce AV data for a window media player, the ENAV engine 3 can call up the window media player. Also, the ENAV engine 3 accesses a network and can get desired information such as the ENAV file.
Particularly, in the present embodiment, the ENAV engine 3 parses language information recorded on a startup file, compares the language information with player language information recorded on a system parameter table, and selects a corresponding loading SUBSTITUTE SHEET (RULE 26) information file according to the compared result. The loading information file includes a list of ENAV files that should be bufFered in advance or during reproducing for seamless reproduction.
The ENAV engine 3 buffers ENAV files according to a selected loading information file in a buffer (not shown) included in the ENAV engine 3 and then interprets and executes from an initial file of the ENAV files.
