DATA PROCESSING DEVICE, DATA PROCESSING METHOD, PROGRAM, PROGRAM RECORDING MEDIUM, DATA RECORDING MEDIUM, AND DATA STRUCTURE

摘要

In a data reproduction device, it is possible to reproduce stream data according to a time stamp even without using a particular clock for counting. In step (S141), it is judged whether a received access unit has a time stamp. When the access unit has a time stamp, step (S142) sets the value of the time stamp (PTS). When the access unit has no time stamp, step (S144) ads the value decided by the previous pic_struct to the current time. After this, in step (S143), the pic_struct of this time is stored for the next processing. The present invention may be applied to a game device using a DVD, for example.
