摘要

本文描述了支持无损视频编码的新型高效视频编码(HEVC)标准的扩展。由于HEVC最初是为有损视频压缩而设计的，因此在无损视频编码中无法提供出色的性能。本文基于无损帧内编码的统计特性，提出了一种新的残差数据编码方法。该方法包括改进的水平编码和二值化表选择与先前编码的水平值加权和。实验结果表明，与HEVC无损帧内编码相比，该方法可节省约2.41%的比特，最高可节省5.34%的比特。

Improved residual data coding for high efficiency video coding lossless extension

This paper describes an extension of the new high efficiency video coding (HEVC) standard for supporting lossless video coding. Since HEVC is originally designed for lossy video compression, it cannot provide outstanding performances in lossless video coding. In this paper, we propose new residual data coding methods based on the statistical characteristics of lossless intra coding. The proposed method consists of improved level coding and the binarization table selection with the weighted sum of previously encoded level values. Experimental results show that the proposed method achieves approximately 2.41% bit saving and reaches up to 5.34% bit saving, compared to HEVC lossless intra coding.
