摘　　要：在ＴＭ５算法的基础上，提出了一种ＭＰＥＧ－２码率控制算法。仿真实验表明，算法对有场景切换连续序列解码后的图象主客观质量有明显改善。Based on algorithm TM5 an algorithm for controlling the bit rate of MPEG-2 is proposed. Simulation experiments show that improvements on objective and subjective quality are significant in decoded pictures with scene switching and continuous sequence.

关 键 词：图象压缩编码 码率控制 视觉特性
