基于H．263编码标准的H．264实时编码器的优化设计

Optimized Design of H.264 Real-time Encoder Based on H.263 Coding Standard

从实时应用角度出发,参考H.263编码标准,对H.264视频编码器进行精简,并对耗时较大的算法进行改进。仿真结果表明,简化后的H.264编码器编码速度达到20f/s(帧/秒),达到实时编码要求,且编码性能优于H.263编码标准的编码器。

According to the real-time requirement and H.263 coding standard, the H.264 video encoder is simplified, and the algorithm which casts most time is improved. The simulation results show that the coding speed of simplified H.264 encoder can be up to 20 f/s, which can reach the real-time requirement. Moreover, the coding performance of concise H.264 encoder is better than standard H.263 encoder.
