Patent ID: 7460564

Claim:
A method for editing a video signal and an audio signal, subjected to time-shared multiplex compression by an MPEG-2 transport method and recorded on a random accessible recording medium, the method comprising: designating a dividing position of the video signal at a boundary of video TS packets constituting a GOP; constructing a constructed stream from a first stream in front of said designated dividing position, a video TS packet present in a second stream behind said designated dividing position, and all audio TS packets present in the second stream corresponding to audio TS packets present in the first stream first overwriting a video TS packet in the constructed stream, not having a corresponding audio TS packet in the first stream, with a dummy TS packet; and second overwriting, in the behind stream, an audio TS packet with a dummy TS packet until an audio TS packet, coinciding with a reproducing timing of a video TS packet at said dividing position, appears.
