Design Considerations

This professional studio-quality video encoding and decoding broadcast scalable platform leverages the processing power of the TMS320C6474 multi-core DSP and the flexibility of the TMS320DM6467 Digital Media SoC to render a truly unique system that can be adjusted to suit the capability of the end product. In this system, the ‘C6474 is used as the codec processor for the 4:2:2 video input. As this block diagram represents the receiving end of the video broadcasting studio end equipment, the GC5325 processor is used extensively in the transmission side of video equipment to send digital data via a fiber optic cable or radio link. An EVM (called the GC5325SEK), which includes a TSW3100 Digital Pattern Generator, is available for this wideband digital predistortion transmit processor.

TMS320C6474 Functionality:

  • In encode mode, raw video is fed via the VPIF/SRIO interface. One of the cores on the daughter card will act as a master and manage all encoding tasks on other C6474 chips/cores.
  • In decode mode, bit streams are fed via the GbE interface; decoded raw video will be sent to the DM6467 for post processing (scaling, etc).
  • Coding tasks can be partitioned via either slicing or functional partition across all 9 cores on the three C6474 DSPs.

Encoder Features:

  • Live MPEG-4, H.264, AVS and WMV9 encoding
  • High-end video compression algorithms, such as H.264 live encoding of synchronized video and audio
  • High-quality and performance with full D1 video and audio code-compatible (AAC)

Decoder Features:

  • Decode either MPEG-2 MP@HL or MPEG-4 AVC (H.264) HP
  • The DM6467 digital media processor can be programmed to support a number of audio and video standards and can be updated easily through software as network configurations and service needs change.
  • The DM6467 combines the DSP with HD video and imaging coprocessors to provide the high-speed computation required for HD video decoding, plus an ARM926 RISC processor for user interfaces, system control and programming ease.

The Core Subsystem Includes:

  • 1080i Analog video input and output
  • HD-SDI input and output
  • AES3 / S/PDIF digital audio input and output
  • Analog audio input and output
  • IP GbE communication
  • Transmission of decoded signal to an HD display for viewing or monitoring in real time
  • For added flexibility, additional high-performance daughtercards for 4:2:2 video processing can be utilized for multi-channel operations.
