SHD1 H264 low-latency decoding playback board

SHD1 is a low-latency H.264 video decoding high-definition playback board developed by VCAN，Rich interface，Fully functional，Flexible configuration。

Function Description：

• SHD1 board implements H.264 video decompression and playback function，Maximum support for 1080P@60fps decoding and playback，Backward compatible with various other resolutions、Frame rate decoding playback。SHD1 decoding board with H264 encoding board(e.g. SUE1、SEM9363)And the use of COFDM transmitting and receiving modules can realize low-latency high-definition digital wireless image transmission function，In the actual test of 720P@60, the video delay can be about 60ms，1080At P@60, the video delay can reach about 130ms。The delay refers to the delay from HDMI video input at the transmitter to HDMI video output at the receiver，Does not include the latency of the transmitter's front-end camera(We actually measured that the delay of a certain brand of SLR camera is about 70ms、The delay of a well-known brand action camera is about 130ms)；
• Support video decryption function(Match with the video encryption of the transmitter)；
• Audio and video output interface：
  • HDMI-A port audio and video output
  • CVBS(lotus head)AV audio and video output
  • 40PIN FPC LCD output(optional)
  • Audio integrated 1W stereo class D power amplifier，Support 1W/8Ω speaker(optional)
• USB Type A port：
  • Stream video to your phone or tablet，Simultaneously realize HDMI video display and mobile phone video display
  • External FC2400A down conversion module，Realize 2.4GHz frequency band COFDM wireless reception, demodulation, decoding and playback
• Parameter configuration serial port(Config UART)：Can be connected to PC or parameter control panel for parameter configuration，It can also be connected to other host computer for parameter configuration(e.g. drone remote control)；
• Transparent data transmission serial port(Data UART)；
• COFDM transmit interface(For software upgrade and maintenance、data storage, etc.)；
• Docking interface of DR2C dual-antenna COFDM receiving module；
• Docking interface of DR900 single-antenna COFDM receiving module；
• 3LED lights：Power Indicator、RF signal reception indicator、record light；
• two buttons：Key1 - OSD on/off，Key2 - record video on/off；
• Dimensions 109.4 x 86mm (COFDM transmit interface)；
• SHD1 PCB board thickness 1.6mm，The highest front component is less than 15mm，No components on the back；
• COFDM transmit interface：6V~15V。

SHD1 decoder board application：

    The SHD1 board can be flexibly used with other modules。The SHD1 board can be used separately with the DR900、DR2C and other COFDM receiving demodulation modules are stacked and assembled together，Form COFDM receivers with different functions，Realize COFDM signal reception demodulation and audio and video decoding output。

1)SHD1 is used with DR900 single-antenna COFDM receiving demodulation module：

2)SHD1 is used with DR2C dual-antenna COFDM receiving demodulation module：

3)SHD1 external FC2400A 2.4GHz band COFDM receiving module：

4)The Config UART interface J22 of the SHD1 board can be connected to an external serial port control panel，Make running parameter settings，Such as working frequency band、Settings such as wireless bandwidth。The picture below is the serial port control panel SconB，SconB is connected to the SHD1 board through a 4PIN cable，Powered by the SHD1 board。
