Function description：

• SHD3 board implements H.264 video decompression and playback function，Maximum support for 1080P@60fps decoding and playback，向下兼容其它各种分辨率、Frame rate decoding and playback。SHD3 decoding board with H264 encoding board(For example SUE1)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 AES decryption function(Encryption matching with transmitter，The password can be set through the SconB parameter panel.)；
• Audio and video output interface：
  • HDMI-A type port audio and video output(HDMI out)
  • 3.5mm four-segment audio socket as audio and video output(AV out/Audio out)
  • 2×10-1.27mm female header LVDS output(Optional, LVDS interface)
  • Audio integrated 1W stereo class D amplifier，Supports 1W/8Ω speakers(Optional, loudspeaker interface)
• USB Host interface：
  • External U disk/mobile hard disk storage
  • Stream video to mobile phone/tablet，Simultaneously realize HDMI video display and mobile phone video display
  • Expand RJ45 Ethernet port via USB to Ethernet Dongle
• 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)。Config UART is RS232 level；
• Transparent data transmission serial port(Data UART)，RS232 level；
• TF card interface(For software upgrade and maintenance、data storage)；
• 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 99.7 x 86 mm(Excluding the dimensions of interface components and connectors protruding from the edge of the board)；
• SHD3 PCB board thickness 1.6mm，The maximum front component is less than 7mm，No components on the back；
• COFDM transmit interface：6V~24V。

SHD3 decoder board application：

The SHD3 board can be flexibly used with other modules of VCAN Company。SHD3 boards are available separately with 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)SHD3 is used with DR900 single antenna COFDM receiving and demodulating module：

2)SHD3 is used with DR2C dual-antenna COFDM receiving and demodulating module：

3)The Config UART interface of the SHD3 board can be connected to an external serial port control panel，Set operating parameters，如工作频段、Configurable convolutional coding ratio、Receive settings such as passwords。The picture below is a schematic diagram of the serial port control panel SconB connected to the SHD3 board through a USB cable.，It is powered by the SHD3 board。

4)The USB Host interface of the SHD3 board can be connected to a smartphone or tablet，Stream video to your phone or tablet for display。VCAN provides the Android APP software Splayer to run on smartphones or tablets for video playback and display.。SHD3 receives COFDM wireless video via DR2C or DR900，Simultaneous output to HDMI display、Video playback on AV monitors and smartphones or tablets。

5)The USB Host interface of the SHD3 board can be connected to an external USB network port adapter，Transmit the COFDM wireless video stream received by DR2C or DR900 to the PC network port or NVR device through the USB network port adapter，Decode and play。

6)The USB Host interface of the SHD3 board is connected to an external USB network port adapter，Input H264 video stream through the network port for low-latency decoding and playback。
