1 1080P/60fps COFDM Wireless Video Transmission System Function Introduction for LE8010 System LE8010-T full HD video transmitter is one of the newest real-time transmission systems that launched by our company for transmission of broadcast HD images. LE8010-T: with small size (180mm*130mm*32mm), light weight(745g), long transmission distance(more than 100KM per 10W) and high resolution(1080p/60fps), 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, brighter colors and image smoothness.

3 COFDM Wireless Full HD Video Transmission MINI System Product Features 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. Therefore, 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 Adjustable working frequency within the range of 300MHz~2.7GHz Rich video/audio interfaces: HDMI, SDI (selectable) High quality digital video processing and H.264 video codec, with high definition display Very low encoding latency: 450ms Stable image and voice transmission under high speed movement and multipath interferences Strong NLOS non line-of-sight transmission With space diversity reception With encryption (selectable) Transmitting power 10W Range of Application It is widely used in UAV (providing disaster relief, emergency rescues and forest-fire prevention), emergency communication, radio and television broadcasting and live broadcasts; individual reconnaissance of field forces; image transmission
