Design And Implementation Of Video Processing System Based On DM648

As rapid development of modern information technology, Digital multimediatechnology has been widely used in various fields of people’s lives, and the traditionaldigital image processing technology has not met the people’s requirement which is theimage quality, the real-time of video and so on. Based on the Davinci DM648processorand the H.264video compression technique, an image processing system, which isinclude hardware and software, is raised in this paper.In this paper, we retrospect the development of digital image processingtechnology, and explain on theory about image processing technology, H.264videostandard, programming framework of DirectShow and so on, and design the videoprocessing system based on DM648. The design process of system’s framework andsoftware subsystem is discussed importantly. Firstly, on the basis of the whole systemfunctions, it introduces the whole system. And it analyzes the needs of the softwaresubsystem by describing the system ’s hardware platform. Secondly, there is a detaileddescription to the specific design of all modules. Lastly, the actually test scheme is putforward, and then results are given.After test, the image processing technology, including hardware and software, canget the higher image quality and the better real-time.
