Abstract
In a communications system packets containing compressed digital signals are transported in multiple cells, typically in an Asynchronous Transfer Mode format. Upon reception of these cells, a determination is made as to whether cells have been lost, additional cells inserted, or whether there were bit errors in the transmission of the cells. If so, null packets are substituted for the erred packets and are sent to the video decompression layer.
