The wireless digital image transmission system adopts the advanced modulation technology COFDM and the channel codes. It combines with digital image compression MPEG2/MPEG4/H.264 multimedia network transmission technology. In condition of high-speed movement and non-line of sight, it can achieve the real time and Synchronous transmission of broadband multimedia services such as Video, Audio, data and so on. The system has features of flexible structure, wide coverage, good mobility, strong ability to combat interference and fading. It is an ideal solution for providing long distance, high quality and high efficiency of wireless real-time transmission which applied in emergency telecommunications such as commanding, emergency rescues, investigation, field battle and so on. This device is wildly applied in fields such as Public security, Armed police, Fire control, Field troops, Broadcasting television, Urban planning management, Civil air defense, Transportation, the Customs, Oil field, Mines, Water project, Electricity, Financial and so on.

As one of the Dexin's key product lunched recent years, the wireless digital image transmitting system device supports input/output of A/V, ASI, SDI and S-Video, adopting MPEG-Ⅱ AV/TV compression, various wideband transmitting function such as 2M, 6M, 7M, 8M and it has full range of system equipment and solution.

It can perform unfixed spot positioning transmitting of ultra remote distance, thus the news and large scale public-service activities programs real time transmitting is achieved

It can transmit close-distance, continuous, and moving(non-vision distance) real-time AV signal.

It can save audio and video.

It has convenient and efficient network transmission.

The emission system can simultaneously send one video, two audio.

It adopts international leading techno
