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. The following figure shows the subsystem architecture with an AXI4-Stream interface.

Figure 1. SMPTE UHD-SDI TX Subsystem (AXI4-Stream I/F) Architecture

The following figure shows the SMPTE UHD-SDI TX Subsystem with native video as the user interface. The Video Timing Controller (VTC) and AXI4-Stream to Video Out cores are not present in the subsystem and the subsystem accepts native video input.

Figure 2. SMPTE UHD-SDI TX Subsystem (Native Video I/F) Architecture

The following figure shows the SMPTE UHD-SDI TX Subsystem with native SDI as the user interface. The subsystem accepts native SDI input and it consists only of the SMPTE UHD-SDI TX IP core.

Figure 3. SMPTE UHD-SDI TX Subsystem (Native SDI I/F) Architecture

The subsystem consists of the following subcores:

  • AXI4-Stream to Video Out
  • Video to SDI TX Bridge
  • SMPTE UHD-SDI TX
  • Video Timing Controller
  • AXI Crossbar
