System and method for detecting and correcting a false embedded header

A method, comprising:

• activating a first output if an ancillary data header is detected in a data stream, wherein the ancillary data header includes a first series of values that indicate an ancillary data packet will follow the ancillary data header;
• activating a second output if a sync header is detected within the ancillary data packet, wherein the sync header includes a second series of values that indicate sync information;
• and
• altering the second series of values to not indicate the sync information if the first and second outputs are activated.

A system, comprising:

• a logic module, comprising:
• a first comparator circuit configured to locate an ancillary data packet in a data stream based on a first sequence of data indicative of the ancillary data packet;
• a second comparator circuit configured to determine if the ancillary data packet contains a second sequence of data indicative of sync information;
• and
• a multiplexer configured to alter the second sequence of data to not indicate sync information if the ancillary data packet does contain the second sequence of data.
