Research On H.264 Video Compression Coding Standard And Its DSP Implementation

With the development of information technology and improvement of network speed,video applications has been into our lives.Under this background. We also need a video code which should have high efficiency and good adapt ability of various networks. H.264/AVC is the newest video international standard designed by both ITU-T VCEG and ISO/IEC MPEG.The new technology improved coding efficiency greatly. However the improvement is based on the cost of rapid increased complexity, which makes it difficulty of real-time coding and transmission of H.264. Based on high-performance Digital Signal Processor to implement. H.264 video encoder is one of most efficient methods. In this paper, firstly, it analyzed the structure of H.264.Then, it intorduced the main technologies of each module of H.264. Based on the research of these main technologies, it select H.264 official JM86 reference model as a reference.It analyzed the process of frame-encoding, slice-encoding and macroblock-encoding. It referenced some motheds of X264, cutting the code and optimizing process of the original C code. Through deeply studying the main techniques and algorithms.UMHexagonS algorithm to be improve.Given some common errors and their correction methods in the process of transplantation. Finally the improved encoding algorithms are transplanted to the DSP chip.
