Recording medium, playback device, integrated circuit, playback method, and program

A playback device for reading a byte-code application from a recording medium on which an index table, an operation mode object, and byte-code applications are recorded, and performing a playback control in accordance with the read byte-code application, comprising:

• a manager operable to select, as a current title, a title from a plurality of titles shown in the index table;
• a platform unit operable to start a byte-code application in accordance with an application management table in an operation mode object corresponding to the selected current title;
• and
• a display control unit operable to initialize a display rate of a display device by using display rate initialization information in the operation mode object corresponding to the selected current title.

An integrated circuit embedded in a playback device for reading a byte-code application from a recording medium on which an index table, an operation mode object, and byte-code applications are recorded, and performing a playback control in accordance with the read byte-code application, the integrated circuit comprising:

• a manager operable to select, as a current title, a title from a plurality of titles shown in the index table;
• a platform unit operable to start a byte-code application in accordance with an application management table in an operation mode object corresponding to the selected current title;
• and
• a display control unit operable to initialize a display rate of a display device by using display rate initialization information in the operation mode object corresponding to the selected current title.

A playback method for reading a byte-code application from a recording medium on which an index table, an operation mode object, and byte-code applications are recorded, and performing a playback control in accordance with the read byte-code application, the playback method comprising the steps of:
