Virtex-6 FPGA 中的三倍速率 SDI

簡介

现金网博e百 描述

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 on Virtex-6 FPGAs solution provides receiver and transmitter interfaces for the SMPTE SD-SDI, HD-SDI, and 3G-SDI standards. The Triple-Rate SDI receiver and transmitter are provided as unencrypted source code in both Verilog and VHDL, allowing the user to fully customize these interfaces as required by specific applications.

主要特性與優勢

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
