The MPEG Decoder and MPEG Formatter can run simultaneously. The
formatter automatically detects when it is out of synchronization with the
decoder and recovers by either waiting for the decoder or by skipping
ahead of the currently processed data. The wait or skip operation is
performed only at MPEG data frame boundaries. The Formatter outputs
Pause bursts when it is in Wait or Skip Mode. The Pc field in the Pause
burst is coded to indicate Wait or Skip Mode (see
