Moving image compression encoding apparatus, method, and control program

There is provided a digital broadcast receiving apparatus comprising an acceptance unit and a change unit. Subsidiary information includes application control information indicating 'finishing' or 'not finishing' the execution of a data broadcast application by an execution unit when a program included in broadcast program data in playback by a playback unit has been switched to another program. The acceptance unit is configured to accept a continuation instruction indicating continuing the execution of the data broadcast application by the execution unit even after a program included in the broadcast program data in playback by the playback unit is finished. The change unit is configured to, when the application control information has indicated &#x201c;finishing&#x201d; and the acceptance unit has accepted the continuation instruction, change the application control information so as to indicate &#x201c;not finishing&#x201d; before the program included in the broadcast program data in playback by the playback unit is finished.

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.
