• Ethernet video stream input，H.264 decoding HDMI output

Function Description：

• SHD3 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。SHD3 decoding board with H264 encoding board(e.g. SUE1)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 AES decryption function(Match with transmitter encryption，The password can be set through the SconB configuration panel)；
• Audio and video output interface：
  • HDMI-A 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 power amplifier，Support 1W/8Ω speaker(optional, loudspeaker interface)
• USB Host interface：
  • External U disk/mobile hard disk storage
  • Stream video to phone/tablet，Simultaneously realize HDMI video display and mobile phone video display
  • Extend 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 computer for parameter configuration(e.g. drone remote control)。Config UART is RS232 level；
• Transparent data transmission serial port(Data UART)，RS232 level；
• COFDM transmit interface(For software upgrade and maintenance、data storage)；
• 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 99.7 x 86 mm(COFDM transmit interface)；
• SHD3 PCB board thickness 1.6mm，The highest front component is less than 7mm，No components on the back；
• COFDM transmit interface：6V ~ 24V。

SHD3 decoder board application：

SHD3 board can be flexibly matched with other modules of VCAN company。SHD3 board can be used separately with 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)SHD3 is used with DR900 single-antenna COFDM receiving demodulation module：

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

3)The Config UART interface of the SHD3 board can be connected to an external serial control panel，Make running parameter settings，Such as working frequency band、Configurable convolutional coding ratio、Settings such as receiving passwords。The figure below is a schematic diagram of the serial port control panel SconB connected to the SHD3 board through the USB cable，Powered by the SHD3 board。

4)The USB Host interface of the SHD3 board can be connected to an external smartphone or tablet，Stream video to your phone or tablet for playback and display。VCAN provides Android APP software Splayer to run on smartphones or tablets for video playback and display。SHD3 receives COFDM wireless video via DR2C or DR900，Simultaneously 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 with an external USB network port adapter，Transmit COFDM wireless video stream received by DR2C or DR900 to PC network port or NVR device through 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。
