  • System parameters 0 through 20 are implemented using a system parameter table according to System Parameters (SPRMs) defined in a DVD-Video standard (DVD specifications for Read-Only Disc Part 3 Video Specifications), considering compatibility.
  • SPRMs System Parameters
  • DVD-Video standard DVD specifications for Read-Only Disc Part 3 Video Specifications
  • one among the system parameters included in the system parameter table can be used as language information, or a new format of system parameter table can be implemented by adding the player language information to the system parameter table.
  • a value having a fixed length of 2 bytes is stored in SPRM and each parameter has a 16-bit integer value.
  • SPRMs 0 through 20 are disclosed in the DVD-Video standard and therefore the descriptions for parameters without direct-relation to the present invention are omitted.
  • SPRM 0 stores information of a language that a user uses to create a DVD-Video menu.
  • the reproducing apparatus 200 compares a value set in SPRM 0 with language information recorded on an ENAV disk 100 , and can select an ENAV application created with the same language as the menu, as an ENAV application to be first executed.
  • the value of SPRM 16 can be changed only when the reproducing apparatus is initialized and cannot be changed while the reproducing apparatus is being reproduced or operated.
  • SPRM 16 stores language information of an audio stream to be reproduced simultaneously when a DVD-Video is reproduced, in a format defined in the ISO-639 standard. Therefore, the reproducing apparatus 200 can select an ENAV application to be first executed, with reference to the value set in SPRM 16 .
  • SPRM 18 also can be changed only when the reproducing apparatus is initialized and cannot be changed while the reproducing apparatus is being reproduced or operated.
  • SPRM 18 stores language information displaying a caption of a DVD-Video, in a format defined in the ISO-639. In most cases, users see a caption of a movie made with their local language while hearing an audio of an original language used where the movie is made. Accordingly, the reproducing apparatus 200 selects an ENAV application, the contents of which are made with the same language as the caption, with reference to the language information displaying the caption in the DVD-Video. That is, the reproducing apparatus 200 selects the ENAV application with reference to the values stored in SPRM 18 .
  • SPRMs 21 through 23 are reserved areas. Accordingly, the present embodiment records the player language information (Initial Language Code) in a format defined in the ISO-639 standard on one among the empty SPRMs, for example, on SPRM 21 .
  • the value of SPRM 21 can also be changed only when the reproducing apparatus is initialized and cannot be changed while the reproducing apparatus is being reproduced or operated.
  • FIG. 10 is a view explaining the data structure of the player language information recorded as the system parameter of FIG. 9.
  • the player language information is recorded using 2 bytes allocated to SPRM 21 .
  • the remaining bits not used in recording the language information thereon are reserved and can be used to store other information.
  • SPRM 21 can be recorded in a format defined in the ISO-639 standard or according to other standards.
  • FIG. 11 is a flowchart explaining a reproduction method according to an embodiment of the present invention.
  • the reproducing apparatus 200 checks a startup file stored in a directory DVD_ENAV and determines whether the loaded disk is an ENAV DVD 100 (operation 1101 ). If the reproducing apparatus 200 cannot find a startup file, the reproducing apparatus 200 determines whether the loaded disk is a conventional DVD-Video disk (operation 1102 ). If the loaded disk is a DVD-Video disk, the reproducing apparatus 200 reproduces the disk in a video mode (operation 1103 ). The reproducing apparatus 200 does not reproduce the disk if the disk is another type of disk.
  • the reproducing apparatus 200 finds a startup file and determines that the loaded disk is the ENAV disk 100 (operation 1101 ) and if a user selects a video mode, the reproducing apparatus 200 reproduces the loaded disk in the video mode (operation 1103 ). If the user selects an interactive mode (operation 1104 ), the reproducing apparatus 200 reads the startup file (operation 1105 ), reads language information recorded on the startup file, and reads a loading information file corresponding to player language information recorded on a system parameter table (operation 1106 ). Then, the reproducing apparatus 200 buffers ENAV files listed in the read loading information file (operation 1107 ), interprets and executes from a first ENAV file, and reproduces selected AV data in the interactive mode (operation 1108 ).
  • the above-described reproducing method may be embodied as a program on a computer readable medium including, but not limited to storage media, such as magnetic storage media (e.g., ROM's, floppy disks, hard disks, etc.), optically readable media (e.g., CD-ROMs, DVDs, etc.) and carrier waves (e.g., transmissions over the Internet).
  • storage media such as magnetic storage media (e.g., ROM's, floppy disks, hard disks, etc.), optically readable media (e.g., CD-ROMs, DVDs, etc.) and carrier waves (e.g., transmissions over the Internet).
  • the present invention provides an information storage medium, having a data structure capable of selecting additional contents made with a language selected by a user or with a predetermined language and reproducing AV data in an interactive mode when an information storage medium storing AV data is reproduced, and a reproducing apparatus and reproducing method thereof.
  • the reproducing apparatus can select an ENAV application to be first executed in the interactive mode and reproduce the selected ENAV application with a language readable by a user.
