Synchronous reproduction apparatus

摘要

A synchronous reproduction apparatus for synchronously reproducing a video signal and an audio signal, receives a multiplexed bit stream in which the following data are packeted: video encoded data obtained by encoding video frames, each frame being a fundamental unit of reproduction of a video signal; video presentation time data showing a time to output a reproduced video signal of each video frame; audio encoded data obtained by encoding audio frames, each frame being a fundamental unit of reproduction of an audio signal; audio presentation time data showing a time to output a reproduced audio signal of each audio frame; and system time data.
