Abstract:
1. A reproduction apparatus comprising: a demultiplexer which separates video data and audio data from a multiplexed stream in which a video stream and an audio stream are multiplexed; a video decoder which decodes the video data; an audio decoder which decodes the audio data; and a controller which supplies a synchronization signal for synchronizing with playback of the video to the audio decoder, wherein the video decoder comprises a time stamp calculator which when the multiplexed stream is randomly accessed to playback at any picture, obtains from the video stream a playback time stamp to specify a playback time of a decoded head picture to be first decoded and then calculates a playback time stamp of a display head picture to be first displayed based on the playback time stamp of the decoded head picture; and wherein the controller supplies the calculated playback time stamp of the display head picture as the synchronization signal to the audio decoder.
