The SMPTE UHD-SDI core implements a SMPTE ST 352 payload ID ancillary data packet insertion capability for the transmitter that works in all SDI modes (SD-SDI, HD-SDI, 3G-SDI, 6G-SDI, 12G-SDI, and dual link HD-SDI). The receive side also detects and captures the four data bytes of ST 352 payload ID packets.
