摘要： 提出了基于对象的监控应用中的编码比特分配算法。算法依据观看者的兴趣将视频对象分成4个等级，针对编码缓冲区的当前情况，给不同的视频对象分配不同的比特，对等级高的对象提高分配的比特数。

Abstract: Aiming at monitoring environment, this article puts forward an object-based bit-allocating algorithm. This algorithm divides video objects into four classes：NVO（New Video Object），MVO（existed Mobile Video Object），SVO（existed Static Video Object），BVO（Background Video Object）, each of them has different priorities. Based on the fullness of encoding buffer, it allocates different amount bits to different types of video objects. Video objects of higher priority can get more bits than in traditional algorithm.
