What are the causes of CC errors?

The continuity counter (CC) is a 4 bit sequence number used to identify each MPEG-2 TS packet. A CC error is a break in the sequence numbers ( 1, 2, 3, 4, X, 6, 7, etc) and indicates a problem with the MPEG-2 transport stream packets themselves caused by any one of the following conditions:

  • Lost packet
  • Out of sequence packet
  • Duplicate packet on a per packet identifier (PID) basis
Typically CC errors are  caused by a dropped Ethernet frame somewhere along the digital video signal path.
