The SMPTE UHD-SDI transmitter subsystem implements a SDI transmit interface in accordance with the SDI family of standards. The subsystem accepts video from an AXI4-Stream video interface and outputs a native video stream. It allows fast selection of top-level parameters, and automates most of the lower level parameterization. The AXI4-Stream video interface allows a seamless interface to otherAXI4-Stream-based subsystems.

Features

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