Abstract

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 markerpacket 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 964,464, filed August 13, 2007. technical field [0003] The present invention relates generally to satellite receiver systems, and more particularly to systems and methods for monitoring and detecting signal errors in satellite transponder systems and determining when to automatically reset the system if errors are detected. Background technique [0004] Digital multimedia receiver systems, such as satellite receivers, suffer from momentary signal loss due to rainfade and other sources of interference. Rain fade and other types of interference ultimately have the same effect - they cause the satellite system to lose some of its normal signal level. Such discontinuous signals may cause system timing and data processing problems due to missing packets. When a problem arises, the receiver can continue to send data from memory, but this ...
