【Abstract】 In the Processing system of the multimedia video and audio information, there are four main modules which act as data communication, processing of audio signals, conversion of composite video signals (PAL or NTSC) and transmission of component video signals (RGB) respectively. This paper discussed how to use new technology and devices to realize high integration for each module and optimization design. Then the high quality of our system is shown in characteristic specifications, function, structure system and so on.更多还原
