Problems solved by technology

[0004] At present, there are a variety of technical solutions for video data compression in the market. There are compression solutions implemented by hardware methods, and compression solutions implemented by software methods. However, the number of frames processed per second is limited by the processor. Efficient processing Not only the cost is high but also the algorithm is complicated, so it is difficult to implement; there are also various compression schemes realized by hardware methods, such as the real-time compression and decompression scheme of video data using chips with special compression and decompression functions, but no real compression scheme has been realized. High-definition video data real-time compression and decompression technical solution
