SHD1 H264 low-latency decoding and playback board

SHD1 is a low-latency H.264 video decoding HD playback board developed by VCAN.，Rich interfaces，Full functionality，Flexible configuration。

Function description：

• SHD1 board implements H.264 video decompression and playback function，Maximum support for 1080P@60fps decoding and playback，Backwards compatible with various other resolutions、Frame rate decoding and playback。SHD1 decoding board with H264 encoding board(For example SUE1、SEM9363)Used with COFDM transmitting and receiving modules to achieve low-latency high-definition digital wireless image transmission function，When actually testing 720P@60, the video delay can reach about 60ms.，1080Video delay can be about 130ms at P@60。The delay refers to the delay from the HDMI video input of the transmitter to the HDMI video output of the receiver.，Does not include the delay of the transmitter front-end camera(We actually measured the delay of a certain brand of SLR camera to be around 70ms.、The delay of a well-known brand action camera is about 130ms)；
• Support video decryption function(Matches the transmitter video encryption)；
• Audio and video output interface：
  • HDMI-A type port audio and video output
  • CVBS(lotus head)AV音视频输出
  • 40PIN FPC LCD output(Optional)
  • Audio integrated 1W stereo class D amplifier，Supports 1W/8Ω speakers(Optional)
• USB Type A port：
  • Stream video to mobile phone or tablet，Simultaneously realize HDMI video display and mobile phone video display
  • External FC2400A downconversion module，Realize 2.4GHz 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 computers for parameter configuration.(For example, drone remote control)；
• Transparent data transmission serial port(Data UART)；
• TF card interface(For software upgrade and maintenance、Data storage, etc.)；
• DR2C dual-antenna COFDM receiving module docking interface；
• DR900 single antenna COFDM receiving module docking interface；
• 3LED lights：Power indicator light、RF signal receiving indicator light、Recording indicator light；
• two buttons：Key1——OSD on/off，Key2——Video recording on/off；
• Dimensions: 109.4 x 86mm (Excluding the dimensions of interface components and connectors protruding from the edge of the board)；
• SHD1 PCB board thickness 1.6mm，The maximum 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 is available separately with the DR900、DR2C and other COFDM receiving and demodulating modules are stacked and assembled together，Forming 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 and demodulating module：

2)SHD1 is used with DR2C dual-antenna COFDM receiving and demodulating 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，Set operating parameters，Such as working frequency band、Settings for wireless bandwidth, etc.。The picture below is the serial port control panel SconB，SconB is connected to the SHD1 board through a 4PIN cable，It is powered by the SHD1 board。
