- Video rate detection
- NRZI decoding and descrambling
- Word alignment
- Demultiplex data links
- Video timing flags extraction
- HD-SDI LN extraction
- HD-SDI CRC
- Payload ID extraction
- Synchronizing data streams
- Accessing transceiver
- Identifying and tracking of ancillary data
- Sync bit removal
