SUE5SA&RCB COFDM Transmitter Module

    -- HD video COFDM transmitter module with SDI/AHD input interface
    -- H.265/H.264 video encoder

SUE5SA&RCB module features SDI/AHD(AV compatible) inputs with COFDM modulation technology and H.265/H.264 encoding that complete video audio transmission in high-speed motion and NLOS (none line of sight) conditions with low latency. SUE5SA&RCB module consists of two boards(video codec board and COFDM modulation board) with flat cable connection. The module also provides one transparent transmission uart(one way).

SUE5SA&RCB module can work in different features mode with different firmware which should be specified before it shipped. The default normal features of SUE5SA&RCB module:

  • H.265 video compression and COFDM modulation
  • Video input via SDI or AHD interface
  • Full HD resolution, maximum 1080p/i @60fps
  • Adjustable working frequency, band width, bitstream rates, RF power, etc.

The default normal features of SUE5SA&RCB transmitter module will be paired with Sihid SHD5&DR2C receiver module. The HD video latency from its inputting of the transmitter to the HDMI screen displaying of the receiver is about 200ms to 250ms.

Specified features implemented with different firmware:

  • Normal H.264 video compression;
    Paired with Sihid SHD4&DR2C receiver module.

  • Proprietary H.264 video compression only used p-frames for lowest latency;
    Paired with Sihid SHD4&DR2C receiver module with specified firmware. The video latency from its inputting of the transmitter to the HDMI screen displaying of the receiver is about 50ms to 130ms.

  • Video input via SDI + AHD interface, two channels video compression and transmitted
    Paired with Sihid SHD5&DR2C receiver module with specified firmware.
