Abstract
Video data and audio data of multiplexed data are separated. Abstract video data is generated from the separated video data and abstract audio data is generated from the separated audio data. Then, the abstract video data and the abstract audio data are packed and a packed video and audio data management table is generated from packed video and audio data D2 and video and audio data synchronization information D3. The packed video and audio data management table comprehensively manages the packed video and audio data. Thus, data of various video formats, various audio formats and various multiplexing formats can be monistically managed.
