System control apparatus for moving picture data

A system control apparatus that can be implemented into a reproduction apparatus together with a drive apparatus, the system control apparatus comprising:

• an interface unit that handles an input and output to and from the drive apparatus;
• a memory;
• and
• a control unit, wherein
• data to be input and output to and from the drive apparatus has a video object and mapping information, the video object including moving picture data and a plurality of pieces of sub-picture data to be selectively reproduced,
• each piece of sub-picture data including still picture data and coordinate information that shows a display position of the still picture,
• the mapping information indicates a correspondence between one of a plurality of display modes when the moving picture data is displayed at one of a plurality of aspect ratios and sub-picture data that includes coordinate information which corresponds to the display mode,
• the memory includes a display setting unit that stores a setting of the display mode of a display device connected to the system control apparatus,
• the control unit (i) performs control of the drive apparatus so as to read program chain information including the mapping information from a recording medium before reproduction of the video object, and (ii) performs control, if the program chain information is read from the recording medium, so as to reproduce, together with the moving picture data, sub-picture data which is included in the video object and has the coordinate information corresponding to the setting of the display mode stored in the display setting unit by acquiring the program chain information via the interface unit to refer to the mapping information included in the program chain information.
