Video and audio stream data recording and playback editing system

摘要

The present invention relates to a video / audio stream data recording and reproducing system for recording, reproducing and editing video / audio stream data in which video data and sound data are mixed. The stream data recording apparatus of the present invention records each video coding unit included in the stream data and the leading edge of a series of voice coding units corresponding to the video coding units in the first order of access units of the storage medium and records them Since the stream data structure and the stream data are accessed by the stream data reproducing apparatus and the stream data editing device of the present invention, the stream data is freely reproduced and edited for each video coding unit by using the random access property of the storage medium It is possible to collect. In addition, according to the stream data recording apparatus of the present invention, it is possible to replace the stream data recorded on the storage medium with new stream data for each video coding unit and to perform the endless recording operation without complicated file operation Can be realized.
