摘要：Respective encoders provide a first and second encoded MPEG-2 data streams for a first and second program respectively. Each stream includes at least video and audio
components. The encoder provides seamless video splice-in and splice-out points. A play-to-air splicer is commanded to switch the broadcast output from the first input stream to the second input streams. The splicer identifies approximately aligned seamless video splice-in and seamless video splice-out points in the respective first and second video streams. The splicer splices the second video stream to the first video stream, but continues to broadcast the first audio stream. The splicer identifies corresponding audio splice-in and splice-out points. The splicer splices the second audio component to the first audio component. The splicer adjusts the decode and presentation times in the second stream after the respective slice-in to be consistent with such times in the first program. A decoder converts the compressed video and audio components output from the splicer into uncompressed form.
