ABSTRACT:
A synchronizing system with a simple structure accomplishes synchronous reproduction without complicating a control circuit for synchronizing video and audio signals with each other. The number of unit audio data blocks to be put in one pack is set in such a way that the difference between the presentation start times for the stream of video data and the stream of audio data in one pack in a predetermined pack period becomes a predetermined value, and the pack carries positional information of the pack in the predetermined pack period to the pack. In a reproducing apparatus, the difference between presentation start times for video signals and audio signals in each pack is acquired by referring to positional information (AAU sequence number) in a stream of packs, transferred by the above transmission method, and at least one of the presentation start times for video signals and audio signals in the stream of packs is controlled so that the difference between the presentation start times coincides with the difference between the presentation start times corresponding to the positional information.
