The Omnitek SDI IP is a highly optimised Xilinx FPGA IP Core to allow the conversion of any SMPTE Serial Digital Interface video data stream into an AXI4-Stream with support for single link (up to 12G-SDI), dual link (up to 6G-SDI) and quad link (3G-SDI). This IP comes as independent Rx and Tx IP. The Rx IP decodes an SDI video stream into a neutral AXI4-Stream and the Tx IP encodes a neutral AXI4-Stream into the chosen SDI video stream format.
