Background
Since the development of the wired video transmission communication technology, the most perfect development of analog video transmission is analog video transmission, such as an AHD transmission system, and the best security field is also a monitoring system of Haikang vision. However, the analog image transmission monitoring system has ideal transmission distance and interference resistance delay, but the image quality is not satisfied by many users. In particular, more and more fields require high definition and ultra high definition video. In recent years, a number of different new schemes for wired transmission of high-definition video are developed. The most typical cable system for transmitting high-definition lossless video is optical fiber transmission. However, optical fiber transmission has the fatal disadvantage that many users cannot receive it, one of which is the high cost, and many fields require control costs. Another fatal disadvantage is that the optical fiber is not suitable for a complex environment such as bending, resulting in many users not being able to use it. Again, it is difficult to achieve two-way communication, i.e. two-way transmission of signals simultaneously over one line, both for analog image transmission and for fiber-optic cable transmission systems. Many cable transmission systems have strict requirements on video formats, video resolutions and the like, and have a limited application range.
