When I enable AV codes into my data output stream and analyse the data the ADV7441A / AD9388A alters 0x00 and 0xFF values?
0x00 and 0xFF are part of the AV-code sequence, so these cannot form part of data. This is how AV code is distinguished from the normal data in a 656 stream. So, when AV-code is enabled, data is saturated between 0x01 and 0xFE.
This is a general question and answer that applies to embedded time codes (encoder or decoder).
