5.1.2. Receiver

The receiver performs the following functions:

  • Video standard detection
  • 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

The block diagrams below illustrate the SDI II IP core receiver (simplex) data path for each supported video standard.

Note: The receive block shown in the diagram is the simplified version of the transmit block in the Triple Rate SDI Receiver Data Path Block Diagram.

For bidirectional or duplex mode, the protocol and PHY management & adapter blocks remain the same for each direction, except the Native PHY IP core, which is configured in duplex mode. The figure below illustrates the data path of a SD-SDI duplex mode.
