COFDM Wireless Video Transmission System

Function Introduction：

全高清视频发射器是最新的实时传输系统，其推出的播高清图像的传输之一.

随着小尺寸 (114毫米*68毫米*24毫米), 重量轻(250G) 传输距离长 (超过每1W 15KM) 高分辨率（1080P / 60fps的）, currently it is the wireless COFDM transmitter for soldier that with the highest resolution, the minimum size, the lightest weight and the longest transmission distance among COFDM full HD image transmission systems in China, and by adopting the advanced COFDM modulation techniques, air broadband and its strong resistance to multi-path interferences, it overcomes interferences brought by multipath reflection and occlusion within usage of simulation and general modulation techniques, with high speed shooting and real time none line-of-sight transmission of high quality full HD video images when moving at high speed, particularly suitable for using under complex environments.

With the H.264 video coding standard, up to 1080P/60 HD resolution （1920*1080P/60fps, backwards compatible to 720P）and HDMI( 3G HD-SDI is selectable) input interface which supports digital video/audio, it is characterized by its image sharpness, 明亮的色彩和图像平滑.

产品特点

It is suitable for high speed data transmission, generally with a channel rate of 8M Hz, which can ensure high quality audio transmission. In addition to its requirements for camera, high quality videos and audios also have high requirements for coding stream and channel rate.

QPSK and 16QAM are available for modulation of each COFDM sub carrier, after which generally with a channel rate of 8M Hz. 因此, H.264 high quality encoding/decoding is allowed, the image resolution in the receiving end can be up to 1920*1080P/60 with backwards compatibility and requirements for latter analysis, storage and editing can also be met.

Product Attributes
