Haida Technology SHD1 COFDM Receive Ground Station Motherboard Introduction

SHD1 is a low delay H.264 video decoding high-definition player developed by Silica, which is rich in interface, full, and flexible. Function Description: SHD1 board implementation H.264 video decompression playback function, up to 1080p @ 60FPS decoding playback, compatible with other various resolution, frame rate decoding playback. SHD1 decoding board with SiHID H264 codes (such as SUE1, SEM9363) and COFDM transmit receiving modules to achieve low delay HD digital wireless map transmission, actual test 720p @ 60 video delay can do about 60ms, 1080p @ 60 times video The delay can do about 130ms. This delay refers to the delay from the transmitted end HDMI video to the receiving end HDMI video output, does not include the delay of the front end camera of the transmitter (we measure a brand SLR camera is about 70ms, and a well-known brand moving camera is delayed at 130 ms); Support video decryption function (matching the transmitter video); Audio video output interface: HDMI-A type end accent video output CVBS (lotus head) AV audio and video output 40PIN FPC LCD Output (optional) Audio integration 1W stereo D power release, support 1W / 8Ω speaker (optional) USB A port: Connect the video stream to your phone tablet, and implement HDMI video display and mobile video display. External SiHID FC2400A down-frequency module, implement 2.4GHz band COFDM wireless reception solution Parameter configuration serial port (Config UART): Connectable PC or parameter control panel for parameter configuration, or other host machine performs parameter configuration (such as drone remote control); Transparent data transmission serial port (DATA UART); TF card interface (for software upgrade maintenance, data storage, etc.); SiHID DR2C Double Antenna COFDM Receive Module Docking Interface; SiHID DR900 single antenna COFDM receiving module docking interface; 3 LED lights: power indicator, RF signal reception indicator, recording indicator; Two buttons: Key1 - OSD Open / Off, Key2-- Record video / off; Size 109.4 x 86mm (excluding the size of the interface device and the connector extending the edge); The SHD1 PCB plate thickness is 1.6mm, the front element is up to 15mm, and there is no component on the back. Power supply voltage: 6V ~ 15V. SHD1 decoding board application: The SHD1 board is flexible to use other modules of SiHID. The SHD1 board can be assembled together with COFDM, such as DR900, DR2C, and form a COFDM receiver of different functions, and implements the COFDM signal reception demodulation and audio and video decoding output. 1) SHD1 with DR900 single antenna COFDM receive demodulation module: 2) SHD1 with DR2C dual antenna COFDM Receive demodulation module use: 3) SHD1 external FC2400A 2.4GHz band COFDM receiving module: 4) The Config UART interface J22 of the SHD1 board can be external to the serial port control panel, and the operation parameter settings are set, such as settings such as operating frequency bands, radio bandwidth. The following figure shows the SiHID serial control panel SCONB, SCONB is connected to the SHD1 board via a 4pin cable, powered by the SHD1 board. Read more
