So , great emphasis is put on the very - low - bitrate ( vlb ) video compression techniques
如此低的目标码率要求，向数字视频压缩技术提出了新的挑战。
In chapter 2 , a brief review of the vlb video compression techniques is presented
第二章，回顾现有的甚低码率视频压缩编码技术和国际标准，选取h
And according to the characteristics of the vlb compression of the monitoring video , we carry out some researches to improve the performance of h . 263 encoder , mainly about the developing of the new bitrate control strategy for the vlb monitoring video coding
并针对监控场景甚低码率压缩的特点，分别进行了h 263高级编码模式性能测试和分析， h 263压缩算法改进，和基于dsp特点的程序结构优化等工作。
Chapter 4 is the main part of this thesis , in which we optimize the motion estimation and idct calculation of the h . 263 encoder program , implement the early detection of all - zero dct coefficients in it , and introduce a new bitrate control strategy to meet the new demands of the vlb monitoring video coding
第四章，对h 263压缩算法进行改进：优化了运动搜索、 idct算法，新增了全零块提前判定，提出了新的码率控制算法。第四章是本文重点内容所在。
