SMPTE SDI

简介

产品描述

支持新兴标准,以降低未压缩 HD 视频传输的成本

Reduce the cost of multichannel SD/HD/3G-SDI designs through integration of SMPTE compliant SDI interfaces alongside audio/video processing in a Xilinx FPGA.

The Serial Digital Interface (SDI), is widely used in broadcast applications for the transport of uncompressed SD and HD digital video streams over coax cable. The LogiCORE™ IP Triple-Rate SDI interface solution provides receiver and transmitter interfaces for the SMPTE SD-SDI, HD-SDI, and 3G-SDI standards.


主要特性与优势

Standards compliance:

  • SMPTE 259 (SD-SDI)
  • SMPTE 292 (HD-SDI)
  • SMPTE 372 (Dual Link HD-SDI)
  • SMPTE 424 and 425 (3G-SDI) including levels A, B-DL, and B-DS
  • SMPTE 352 (Payload ID)
  • SMPTE RP-165 (SD-SDI EDH)

Triple-Rate SDI receiver features:

  • A single reference clock frequency supports reception of five different bit rates:
    • 270 Mb/s SD-SDI
    • 1.485 Gb/s HD-SDI
    • 1.485/1.001 Gb/s HD-SDI
    • 2.97 Gb/s 3G-SDI
    • 2.97/1.001 Gb/s 3G-SDI
  • Automatically detects incoming SDI standard and bit rate
  • Automatically detects video transport format
  • Detects and captures SMPTE 352 packets
  • Checks for CRC errors for HD-SDI and 3G-SDI
  • Optionally checks for EDH errors for SD-SDI

Triple-Rate SDI transmitter features:

  • Only two reference clock frequencies are required to transmit five different bit rates:
    • 270 Mb/s SD-SDI
    • 1.485 Gb/s HD-SDI
    • 1.485/1.001 Gb/s HD-SDI
    • 2.97 Gb/s 3G-SDI
    • 2.97/1.001 Gb/s 3G-SDI
  • Generates and inserts CRC and line numbers for HD-SDI and 3G-SDI
  • Generates and inserts EDH packets for SD-SDI
  • Generates and inserts SMPTE 352 packets for all SDI standards
