SHD5&DR2C COFDM Receiver Module

    - 160MHz~860MHz HD video COFDM receiver module with HDMI/AV/USB output
    - H.265 video decoder

The SHD5&DR2C COFDM receiver module is a compact digital diversity receiver with integrated H.265 decoding, suitable for use in fluid and high-mobility applications. The receiver module accepts signals from two antennas to significantly enhance the demodulated performance and increase the operating range. The receiver module can find and lock automatically to the incoming transmission quickly according to the pre-set frequency and bandwidth. This receiver module features a range of comprehensive signal outputs including HD at 720p and 1080P, down-converted HD CVBS monitor video, and two analog audios is supported.

The receiver module also includes DVR record functionality with Micro SD card or USB disk. The receiver module also enables video streaming over USB for remote Android device decoders like Smart phone or Android PAD. This allows multiple remote viewers to monitor the same video simultaneously. The receiver module also supports display characters string on the video display screen with the video together in OSD mode.

When paired with the Sihid COFDM transmitter module, the receiver module offers a comprehensive, rapidly-deployable video and audio solution that enables advanced situational awareness. It can play an essential role in delivering real-time live video from both ground and airborne mobile platforms.

• COFDM demodulation and H.265 video decoder
• Full HD resolution, 1080P@60fps
• Great security by AES decryption
• DVR record with Micro SD card or USB disk
• Enables video streaming over USB host for remote device
• Supports display characters string on the video display screen in OSD mode
• Stable signal transfer in NLOS and high speed moving
• Adjustable working frequency, band width

Paired with COFDM transmitter

The default normal features of SHD5&DR2C receiver module can be paired with Sihid H.265 transmitter module like SUE5&RCB, SUE5SA&RCB. The HD video latency from its inputting of the transmitter to the HDMI screen displaying of the receiver is about 200ms to 250ms.

The SHD5&DR2C module can also be paired with SUE5&RCB transmitter module(or SUE5SA&RCB module) for two channels video transmission when manufactured with specified firmware. The specified firmware enables SHD5&DR2C module to decode two channels H.265 video and send to display with button switch for channel one, channel two, channel one plus channel two on one screen.
