Problems solved by technology

As the display content becomes more and more complex, the demand for high-quality, high-bandwidth, large-flow, and interactive video information is more urgent. The traditional one-to-one wired video transmission and display method can no longer meet the needs of multiple platforms in reality. The need for video information sharing on location screens and video on-demand, timely distribution and interaction requires a new generation of video processing and display devices to have higher integrated video comprehensive display, distribution and switching capabilities

For huge and complex special-purpose facilities or systems, to realize long-distance transmission of video information, traditional video cables and video communication protocols are far from meeting the requirements. Converting video signals into network signals is carried out on Gigabit or even 10 Gigabit networks. Transmission can theoretically solve the bottleneck of high-bandwidth video signal transmission distance, and can extend the transmission distance to hundreds of meters, but its transmission cost is very high, and the signal anti-interference ability is not strong
