Implementation And Application Of H.264 Video Decode Base On DM642 Plaform

The video communication technology is one of most important Applied Research Communications ways .At present, H.264 video compression standard is widely accepted and applied to the video communication system as a new type of standards with its perfect compression ratio and image quality. But, the superior performance of H.264 is base on that its complexity is more than others, so normal processing platform can't meet the complexity of H.264. C64 chip series produced by TI is the H.264 codec ideal platform, has a strong ability to processing and signal processing functions, With the development of embedded technology, embedded system platforms based on the design of network interface which achieve real-time network video transmission has become one of most important aspect of the embedded video communication system developed in the course of produce.In this paper, we have done a more detailed analysis on the H.264 video compression standard , talk about the process of specific implementation and optimization on the H.264 standard reference model in jm86 Wintech's DM642 processing platform . and introduced the applications and development of a micro-operating system, DSP / BIOS. Through using the DSP / BIOS operating system, we can deal with the realization of multi-tasking operation. In addition, the pater also detailly introducs the principle of reference frame of RF5,and debelops the multi-algorithm , the multi-data channels standardized procedure in its foundation to Have the big significance.Then the author make detailed analysis on the DSP6000 Series Network Driver Development Kit. And Implement the video network driver base on VDPDM642 platform by using socket API and DSP / BIOS of NDK. Finally, the author combine H.264 decoding and network drives to form a simple terminal, and realize the functions of the network. And the test indicates that H.264 dencoding system can be implemented on VDPDM642 chip with a better performance.
