摘要

边信息的生成是分布式视频编码(DVC)中的主要问题之一。这可以通过两个最接近的关键帧之间的运动补偿时间插值(MCTI)来执行。但是，当关键帧之间的时间距离增加时，其线性插值的效果会降低。本文介绍了一种适用于长图像组(GOP)尺寸的DVC的分层边信息生成结构。此外，提出了两种量化参数控制技术。实验结果验证了算法的有效性。

A study on hierarchical side information generation structure in Distributed Video Coding

Side Information generation is one of major problems in Distributed Video Coding (DVC). This can be performed by motion compensated temporal interpolation (MCTI) between two closest key frames. However, when temporal distance between the key frames increases, its linear interpolation becomes less effective. This paper introduces a hierarchical side information generation structure applicable to DVC with long Group of Picture (GOP) sizes in mind. Moreover, two quantization parameter control techniques are proposed. Experimental results verify efficiency of the proposed algorithms.
