The transmitter section has the following features:
- Optional generation and insertion of CRC values for error detection on each line for all modes except SD-SDI.
- Optional generation and insertion of RP 165 EDH packets for error detection in SD-SDI mode.
- Optional formatting and insertion of line numbers into all data streams immediate after the EAV in all modes except SD-SDI.
- Optional generation and insertion of ST 352 payload ID packets on up to 8 different elementary data streams.
- Supports 1, 2, 4, 8, or 16 data stream multiplexing.
- Automatic sync bit insertion (run length mitigation) for 6G-SDI and 12G-SDI modes. While this sync bit insertion is mandatory in the 6G and 12G-SDI standards, it can be disabled in the SMPTE UHD-SDI transmitter via a control port to support fielded equipment designed before the standards were released that do not support the sync bit insertion feature.
- Hooks are provided to allow the user application to insert ancillary data into the elementary data streams after the SMPTE UHD-SDI transmitter has inserted ST 352 packets, but before any other processing of the data streams occurs.
