HD SDI Transmitter Encoder COFDM Module For NLOS Video Audio Data Transmission

HD-SDI COFDM Transmitter Modulator Encoder For NLOS Video Audio Data Transmission

Brief introduction:

The COFDM transmitter module consists of video encoder board and COFDM modulator board, it adopts COFDM modulation and H.265/H.264 encoding technology, enable low latency wireless video audio transmission in high-speed movement and non-line-of-sight (NLOS) conditions. It also provides one way transparent transmission serial port.

The COFDM transmitter module can operate in various functional modes with different firmwares. Settings can be clearly stated before shipment. The default regular functions as below:

• H.265 video compression and COFDM modulation.
• Video input via SDI or AHD interface.
• Full HD resolution,1080p/i @60fps.
• Working frequency, band width, video stream bitrates, RF power, etc can be adjustable.

The default normal function of the COFDM video transmitter module will be paired with our HD5 receiver module. The delay of the HD video displayed on the HDMI screen from the transmitter input to the receiver is about 200 ms to 250 ms.

Specific functions implemented with different firmwares

• Standard H.264 video compression: paired with HD1 or HD4 receiver modules.
• Proprietary H.264 video compression only uses P- frames for lowest latency: paired with HD1 or HD4 receiver modules and equipped with specific firmware. From the input signal of the transmitter to the HDMI screen display of the receiver, the video delay is about 50 ms to 150 ms.
• Video input via SDI + AHD interface to achieve two-channel video compression and transmission: paired with HD5 receiver module with specified firmware.
