Reproduction apparatus for cyclically changing sub-data

A reproduction apparatus for reproducing video data in which a piece of moving picture data and a plurality of pieces of sub-data are interleaved, the plurality of pieces of sub-data being reproduced selectively and synchronized with the piece of moving picture data, each piece of sub-data being assigned with an ID, the reproduction apparatus comprising:

• a holding unit configured to hold a table that shows correspondence between (i) route information specifying a combination of pieces of video data to be reproduced sequentially, (ii) logical numbers of sub-data, (iii) IDs of sub-data, and (iv) the pieces of video data specified by the route information;
• a determining unit configured to determine, based on the table and a predetermined logical number, a piece of sub-data to be reproduced;
• a reproducing unit configured to reproduce moving picture data included in the pieces of video data in accordance with the route information, together with the piece of sub-data determined by the determining unit;
• and
• a receiving unit configured to receive an instruction input by a user and change the predetermined logical number cyclically in accordance with the received instruction.
