Abstract
A system and method for a seamless splicing/spot insertion strategy for MPEG-2 digital video/audio transport stream with no previously encoded information. This strategy, considering the time dependency between MPEG-2 frames, results in a new stream with smooth transition from a main stream to a spot stream without any encoded mark increasing possibilities for utilization of MPEG-2 contents. This strategy further facilitates local and remote switching (like local advertisement insertion) and produces successful decoding and presentation of all MPEG-2 packets around the splicing point. It takes into account several kinds of MPEG-2 related discontinuities: transport header continuity counter gaps, temporal reference discontinuity for frame presentation and PCR/PTS/DTS discontinuities.
