摘要

围绕视频编码核心技术，简单介绍AVS视频编码标准发展历程，详细介绍了最新一代AVS视频编码标准——AVS2（GB/T 33475.2-2016）的核心创新技术，主要包括：灵活的预测划分方式、多假设帧间预测、优化的层次变换设计和自适应环路滤波处理技术以及面向场景视频应用 AVS2 提出的基于场景建模的高效预测编码技术。和第一代AVS视频编码标准相比，AVS2编码效率提升一倍以上；和同期HEVC/H.265国际标准相比， AVS2在场景视频编码方面有显著优势。另外简单介绍了AVS标准在数字电视广播等行业中的应用情况。

Abstract

A brief introduction was given to the development history of AVS video coding standards.Then an overview of the key technologies adopted in AVS2 video coding standard (GB/T 33475.2-2016) was provided

including flexible prediction partition

multiple hypothesis prediction

optimized two-level transform

adaptive loop filter and background picture model based prediction coding for scene video.Compared to the AVS1

AVS2 can achieve more than 50% bits saving.And compared to HEVC/H.265

AVS2 can achieve significant coding efficiency improvement for scene video coding.Moreover

the applications of AVS standard in digital TV broadcasting was introduced briefly.
