The Society of Motion Picture and Television Engineers (SMPTE) UHD-SDI receiver subsystem implements an SDI receive interface in accordance with the SDI family of standards. The subsystem receives video from a native SDI and generates an AXI4-Stream video. The subsystem allows fast selection of the top-level parameters, and automates most of the lower level parameterization. The AXI4-Stream video interface allows a seamless interface to other AXI4-Stream-based subsystems.


  • Supports AXI4-Stream, native video and native SDI user interfaces
  • Support for 2 pixel per sample
  • 10-bit per color component
  • Supports YUV 4:4:4, YUV 4:2:2, and YUV 4:2:0 color space
  • AXI4-Lite interface for register access to configure different subsystem options
  • Audio support
  • Standards compliance:
    • SMPTE ST 259: SD-SDI at 270 Mbps
    • SMPTE RP 165: EDH for SD-SDI
    • SMPTE ST 292: HD-SDI at 1.485 Gbps and 1.485/1.001 Gbps
    • SMPTE ST 372: Dual Link HD-SDI
    • SMPTE ST 424: 3G-SDI with data mapped by any ST 425-x mapping at 2.97 Gbps and 2.97/1.001 Gbps
    • SMPTE ST 2081-1: 6G-SDI with data mapped by any ST 2081-x mapping at 5.94 Gbps and 5.94/1.001 Gbps
    • SMPTE ST 2082-1: 12G-SDI with data mapped by any ST 2082-x mapping at 11.88 Gbps and 11.88/1.001 Gbps
    • Dual link and quad link 6G-SDI and 12G-SDI supported by instantiating two or four SMPTE UHD-SDI RX subsystems
