Problems solved by technology

However, the traditional video image processor is limited by the clock and internal structure, and the processing speed is slow. Even if the processing speed is improved by using a dedicated video processing chip, product developers cannot easily modify the fixed-function hardware because it is not programmable. , making it support new standards or different functions, lack of flexibility
Secondly, the traditional video image processor has a single function, and generally realizes specific processing functions for specialized fields, and has poor versatility.
In addition, the traditional video image processor has a long development cycle, slow equipment upgrade speed, high cost, and relatively low cost performance
Therefore, there is currently no video image processor with a wider range of applications such as stronger processing functions, more output channels, and more output specifications to support powerful broadcast video equipment.
