The SMPTE UHD-SDI Transmitter (TX) Subsystem allows you to quickly create systems based on SMPTE SDI protocols. It accepts either an AXI4-Stream video stream, native video stream, or native SDI stream. It outputs a native SDI stream when combined with the SMPTE UHD-SDI core. The top level customization parameters select the required hardware blocks needed to build the subsystem. This Figure shows the subsystem architecture with an AXI4-Stream interface.
