摘　　要：H.264标准是压缩率和图像质量方面的关键新技术,研究H.264通过对传统的帧内预测、帧间预测、变换编码和熵编码等算法的改进来进一步提高编码效率和图像质量,给出了基于C代码的宏块编码流程与复杂度测试,仿真结果证明H.264具有更高的压缩比、更好的IP和无线网络信道的适应性。H.264的高压缩率是以复杂度为代价,其复杂度是以耗时为依据的。H. 264 standard is the key technology about better image compression and image quality based on motion compensation and transform. H. 264 uses intra prediction, inter prediction, transforming coding, enhanced entropy coding algorithms to promote the intra encoding efficiency. The macro - block coding based on C and complexity test are presented. Experimental results show that H. 264 has higher encoding efficiency,better IP and wireless network adaptability. The complexity of H. 264 is on the basis of time cost.
