ABSTRACT:
An editing of a video signal and an audio signal time-shared multiplex compressed by an MPEG-2 transport method designates a dividing position of the video signal at a boundary of video TS packets constituting a GOP, constructing a stream in front of said designated dividing position so as to include all audio TS packets corresponding to video TS packets present in the stream, overwriting a video TS packet, not having a corresponding audio TS packet in the stream, with a dummy TS packet, and overwriting, in a stream behind said designated dividing position, 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. Thus a defective data reproduction resulting from a discontinuity in the data structure of audio frame before and after the dividing position can be avoided.
