Audio/video data recording/reproduction apparatus, system, and method, recording medium recorded by them, audio/video data reproduction apparatus, and data structure

摘要

An audio/video data recording apparatus capable of describing a recording start time directly in a play list when reproducing a moving picture by specifying a time interval. When recording a moving picture, a recording start time is recorded as a time code in a GOP header which is management data for each of the contiguous portions (#0, #1) in each moving picture file. When reproducing the moving picture, a moving picture reproduction interval is specified by using the recording start time held in the time code field in the GOP header.
