Function Description:
SHD4 board implementation H.264 video decompression playback function, up to 1080P @ 60fps decoding playback, compatible with other various resolution, frame rate decoding playback. SHD4 decoding board with SiHID H264 encoding board (eg SUE1) and COFDM transmit receiving module uses to achieve low delay HD digital wireless graphics function, actually test 720p @ 60 video delay can do about 60ms, 1080P @ 60 video delay 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 AES decryption function (match the transmitting terminal encryption, you can set password by the Panel ";
Audio video output interface:
HDMI-A type end accent video output (HDMI OUT)
AV audio and video output (6PIN port)
USB HOST interface Output to mobile phone or tablet
Ethernet port output
USB HOST interface:
External U disk / mobile hard disk storage
Connect the video to your mobile / tablet, and implement HDMI video display and mobile video display
Parameter configuration serial port: Connect PC or parameter control panel for parameter configuration, or other host machine perform parameter configuration (such as drone remote control). Config UART is TTL 3.3V level;
Transparent data transmission serial port (DATA UART), TTL 3.3V level;
TF card interface (for software upgrade maintenance, video storage, etc.);
SiHID DR2C Double Antenna COFDM Receive Module Docking Interface;
Keys + LEDs: Can be taken out for power indicators, RF signal reception indicators, recording indicators, OSD on / off buttons, Record on / off button;
Ethernet Ethernet port: video input or output interface;
Power IN interface: Supports power input from 9 to 30V;
Size 80.4 x 50.8 mm (excluding the size of the interface device and the sidewase of the plug-in).
SHD4 decoding board application:
1) The SHD4 board is equipped with the Haida DR2C Double Antenna COFDM Receive the demodulation module to form a complete COFDM receiving decoding function. :
2) The CONFIG UART interface of the SHD4 board can be external to the serial port control panel, run parameter settings, such as operating frequency bands, wireless bandwidth, receiving password, system time, etc. The following figure shows that the SiHID serial control panel SCONA is connected to the SHD4 board via a 4pin cable, powered by the SHD4 board.
3) The SHD4 decoding board can also decode the play output via the network port input H.264 video stream, and the software can burn the corresponding version of the firmware according to the user needs. For such applications, customers need customers contact Silongha.
4) The SHD4 board can transmit the COFDM wireless video stream received by the DR2C to the PC or NVR device via the network port to decode playback. For such applications, customers need customers contact Silongha.
5) The SHD4 board receives OSD superimposed data (satisfying "SiHID OSD OSD OSD OSD OSD OSD OSD OSD OSD), and the received OSD superimposed data is superimposed on the video screen in text, read the full text
