摘　　要：为降低编码复杂度以满足实时应用的需求,以联合专家组(JVT)发布的H.264参考模型JM8.6为基础,分析H.264软件编码器的结构,指出影响编码速度的瓶颈所在,对H.264软件编码器进行全面优化。试验结果显示,优化后的编码器速度有了很大提高,对在DSP上实现实时编码具有重要的实用价值。Based on H. 264 reference model JM8.6, released by the Joint Video team （JVT）, the structure of H. 264 software encoder is analyzed to decrease the computational complexity of video coding and to meet the real - time application requirements. The bottleneck of affecting speed is pointed out, and the H. 264 software encoder is fully optimized. Simulating result shows that the optimized encoder has high performance and has very important real value to the realization of H. 264 real - time encoder based on DSP.
