摘要
高清视频数据量大给视频传输和存储带来困难,单纯增大带宽和存储容量已不现实。依据H.264视频压缩标准原理和TI高性能Davinci处理器特性,设计了基于DM6467的DSP(/ARM)+FPGA架构的高清视频压缩实时显示和存储硬件平台,并给出了H.264压缩算法实现方法。通过对视频序列进行验证,仿真结果表明,在峰值信噪比较高时,仍能得到约20倍的压缩比,同时具有良好的实时性。
Huge data of high definition video brings great challenges to video transmission and storage,whats more,simply increasing bandwidth and storage capacity have been unrealistic.According to the H.264 video compression standard principle and TI Davinci high performance processor features,the high-definition video compression real-time display and storage hardware platform based on DSP(/ARM)+ FPGA architecture of DM6467 are designed in this paper.The H.264 compression algorithm implementation method is proposed.Video sequence is verified through the experiment.The result shows that when the PSNR is high,this design still can get a compression ratio about of 20 with a good real-time performance.
