Abstract
A digital compressed video signal transmission system includes a transport processor for segmenting compressed MPEG video data into transport cells for transmission. Several protocol levels are utilized to uniquely define transmitted data, provide system synchronization and to provide for detection of lost or corrupted data. Transport cells are formed of three levels, the first of which indicates the service to which the data relates and includes a field indicating the state of signal scrambling. The second level includes a field identifying the one of several alternative formats in which the cell payload is arranged, and a continuity count for determining data continuity. The third level includes the payload and a field which indicates decodable entry points for re-entering the data stream after having lost data.
