Supports emerging standards for lowering cost of uncompressed HD video transport
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.
SMPTE SDI
Overview
Key Features
- 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)
- 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
- 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
