Recording medium, reproduction device, program, reproduction method, and recording method

A recording medium having video data, a plurality of programs, and a table recorded thereon, wherein

• each of the plurality of programs shows a playback control procedure of the video data,
• the table includes (1) identification information of each of the plurality of programs, and (2) information showing that each of the plurality of programs belongs to one of a movie-mode and an enhanced-mode,
• one of the plurality of programs includes a command for branching, and
• the branching command specifies a branch destination using indirect referencing via the table.

A playback device relating to a recording medium having video data, a plurality of programs, and a table including indexes pertaining to the respective plurality of programs recorded thereon, comprising:

• a plurality of modules operable to execute the respective plurality of programs, the plurality of modules including a module corresponding to a movie-mode and a module corresponding to an enhanced-mode;
• and
• a manager operable to control branching between the plurality of programs, wherein
• the table is information showing that each of the plurality of programs belongs to either a movie-mode or an enhanced-mode,
• the branching is described, for each of the plurality of programs, using indirect referencing via the table, and the manager decides, at a time of the branching, a module for executing a program of a branch destination by referring to the table.

A playback processing program relating to a recording medium having video data, a plurality of programs, a table including indexes pertaining to the respective programs recorded thereon, comprising the following processing:

• having a computer perform a plurality of execution steps in each of which one of the plurality of programs is executed, and a control step for controlling branching between the plurality of programs, the plurality of execution steps including an execution step corresponding to a movie-mode and an execution step corresponding to an enhanced-mode, wherein
• the table is information showing that each of the plurality of programs belongs to either a movie-mode or an enhanced-mode,
• the branching is described, for each of the plurality of programs, using indirect referencing via the table, and
• the control step is a step for deciding, at a time of the branching, an execution step for executing a program of a branch destination by referring to the table.

A playback method relating to a recording medium having video data, a plurality of programs, a table including indexes pertaining to the respective programs recorded thereon, comprising the following steps:

• a plurality of execution steps in each of which one of the plurality of programs is executed, the plurality of execution steps including an execution step corresponding to a movie-mode and an execution step corresponding to an enhanced-mode;
• and
• a control step for controlling branching between the plurality of programs, wherein
• the table is information showing that each of the plurality of programs belongs to either a movie-mode or an enhanced-mode,
• the branching is described, for each of the plurality of programs, using indirect referencing via the table, and
• the control step is a step for deciding, at a time of the branching, an execution step for executing a program of a branch destination by referring to the table.

A recording method of a recording medium, comprising the following steps:

• creating application data;
• and
• recording the created application data on the recording medium, wherein
• the application data includes video data, a plurality of programs, and a table,
• each of the plurality of programs shows a playback control procedure of the video data,
• the table includes (1) identification information of each of the plurality of programs, and (2) information showing that each of the plurality of programs belongs to either a movie-mode or an enhanced-mode,
• one of the plurality of programs includes a command for branching, and
• the branching command specifies a branch destination using indirect referencing via the table.
