Low delay H.264 audio and video decoding HD playing board, maximum support 1080p @ 60 real-time decoding
Wireless reception video stream input, H.264 decoded HDMI output, and USB or Ethernet video stream output
Ethernet video stream input, H.264 decoded HDMI output
Function Description:
SHD2 board implementation H.264 video decompression playback function, up to 1080P @ 60fps decoding playback, compatible with other various resolution, frame rate decoding playback. SHD2 decoding board with SiHID H264 encoding board (eg, SUE1) and COFDM transmit receiving module uses to achieve low delay HD digital wireless graphics function, actual 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 (matching the transmitting terminal);
Audio video output interface: HDMI-A port
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
External SiHID FC2400A down-frequency module, implement 2.4GHz band COFDM wireless reception solution
Parameter configuration serial port (Config UART TTL level, 3.3V): Accessible PC or parameter control panel for parameter configuration, or other host machine perform parameter configuration (such as drone remote control);
Transparent data transmission serial port (DATA UART TTL level, 3.3V);
TF card interface (system software / upgrade maintenance);
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;
RJ45 Ethernet interface: After the received wireless COFDM demodulation, data (audio and video or data) can be transmitted through the network port, and the rear end is connected to the PC or NVR. You can also enter the video stream via the network port, and the H.264 decoding playback HDMI output is displayed;
The SHD2 module consists of two PCB stacks, size 64 x 50mm (excluding the size of the interface device and the sidewase of the connector), the maximum thickness of 25 mm. The total thickness is about 28mm thick after plugging the DR2C module or the DR900 module;
Power supply voltage: 6V ~ 13V.
SHD2 decoding board application:
The SHD2 board is flexible to use other modules of SiHID. The SHD2 board can be assembled together with a COFDM such as DR900, DR2C, and the COFDM receiver of different functions can be formed by the USB port external FC2400A, and the COFDM signal receives demodulation and audio and video decoding output. Or implement the COFDM wireless broadband data UDP transmission function.
1) SHD2 with DR900 single antenna COFDM receive demodulation module:
2) SHD2 with DR2C dual antenna COFDM receive demodulation module:
3) SHD2 external FC2400A 2.4GHz band COFDM Receive Module:
4) The Config UART interface of the SHD2 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 SHD2 board via a 4pin cable, powered by the SHD2 board.
5) The USB HOST interface of the SHD2 board can be external to the smartphone or tablet, transfer the video stream to the phone or playback display. Silica provides Android App Software Splayer running on smartphones or tablets for video playback. Silica SHD2 receives COFDM wireless video through DR2C or DR900, which can be output to the HDMI monitor and smartphone or tablet.
6) The SHD2 board can transmit the COFDM wireless data signal received by the DR2C or DR900 to the PC or NVR device via the network port, and perform backend processing or decoding playback. For such applications, the SHD2 firmware must be replaced, and the special version of the software must be replaced, and the customer needs to contact Silica.
7) The SHD2 board can also be used as an independent low delay H.264 decoding board, and the H.264 video stream is lowered by the network port. Decoding. For such applications, the SHD2 firmware must be replaced, and the special version of the software must be replaced, and the customer needs to contact Silica. Read more
