| Abstract: | This paper uses High-definition video encoding as the entry point. A high-performance video encoding ASIC is introduced firstly. Then from the introduction of overall framework of Video Encoding Equipment, the hardware and software design of Video Encoding Equipment are introduced as well. For the hardware design part, we describe in detail the principle of several kinds of commonly used video encoding design, dividing the chapter to carry on the study. For the software design part, we mainly discuss the software architecture and software process of Video Encoding Equipment. It is observed that the design of Video Encoding Equipment becomes increasingly simple, and the function of Video Encoding Equipment becomes more and more powerful and the performance of Video Encoding Equipment becomes more and more reliable because of ASIC. |
