摘　　要：基于传统视频可分级编码效率低、运动矢量幅值小等问题,提出运动矢量基础上能够实现可分级的视频编码方法。对运动矢量的可分级编码是一个重要要求,特别是在低码率或者小图像中。针对这一问题,笔者提出了一种基于运动矢量的视频可分级编码思想,引入可分级编码概念对运动矢量可分级的视频编码方法予以研究。结果证明,可分级视频编码能够促使视频流适应多种不同网络环境及用户终端,呈现出明显的容错性与可分级性。对比特流进行截取,促进质量分级,经过试验验证,其可行性得到证实,提示该方法的可行性与有效性。Based on the problems of low coding efficiency of video and small value of motion vector, the method of video coding can be achieved on the basis of motion vector.The hierarchical coding of motion vectors is an important requirement, especially in low code rate or small image. Aiming at this problem, the author proposes a video hierarchical coding idea based on motion vector, which can be used to study the method of video coding which can be classified by hierarchical coding concept.The hierarchical video coding can enable the video stream to adapt to a variety of different network environments and user terminals, presenting obvious fault tolerance and gradability.The feasibility and validity of this method are verified by the test and verification of the interception of bitstream and the promotion of quality classification.
