SDI Analog High Definition Input COFDM Transmitter Module With AES256 Encryption

SDI Analog High Definition Input COFDM Transmitter Module With AES256 Encryption

Brief introduction:

The SDI COFDM transmitter module has SDI/AHD (AV compatible) input interface, adopts COFDM modulation and H.265/H.264 encoding technology, which can complete video audio transmission with low latency in high-speed movement and non-line-of-sight (NLOS) conditions. The transmitter module consists of two boards (video codec board and COFDM modulator board). It also provides one transparent transmission serial port (unidirectional).

The SDI COFDM transmitter module can operate in various functional modes with different firmware. Settings should 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.
• Adjustable working frequency, band width, video stream bitrates, RF power, etc.

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

Specific functions implemented with different firmware:

• 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 approximately 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.
