ERROR DETECTION AND RECOVERY IN A DIGITAL MULTIMEDIA RECEIVER SYSTEM
摘要
<p>A method for detecting errors in a digital multimedia receiver system is disclosed including the steps of receiving a packetized bitstream representing a video program from at least one of a plurality of transponders in the receiver system, the packetized bitstream periodically including a marker packet having data relating to a continuity counter value, and counting each occurrence of the marker packet in a first counter. The continuity counter value is evaluated at the occurrence of each counting and a second counter is incremented if each continuity counter value is one higher than a previously evaluated continuity counter value. It is determined whether a valid bitstream is being received by comparing values of the first and second counters at predetermined time intervals.</p>
