    History and Recent Developments of AVS Video Coding Standards

    • 摘要: AVS(audio video coding standard)工作组是“数字音视频编解码技术标准”工作组的简称,由国家原信息产业部科学技术司于2002年6月批准成立.工作组的任务是制(修)订数字音视频的压缩、解压缩、处理和表示等共性技术标准,为数字音视频设备与系统提供高效经济的编解码技术.经过10多年的努力,AVS已经成功制定一系列标准,如AVS1,AVS+和AVS2.其中AVS1和AVS2的说法源于AVS第1阶段和第2阶段的工作或第1代、第2代标准.AVS+是工作组专门为高清数字电视广播制定的一个标准.目前AVS1和AVS+标准已经制定完成并成功应用于许多行业中,AVS2也即将完成.将对AVS的AVS视频标准12年来的技术发展过程给以概述,并简单介绍目前最新一代视频编码标准AVS2关键技术,最后对视频编码技术的未来发展方向予以展望.

       

      Abstract: AVS(audio video coding standard) is the informal name of Work group for Digital Audiovideo Coding Standard of China, which was founded by the Science and Technology Department under former Ministry of Information Industry in June 2002, approved by Standardization Administration of China. The role of the group is to establish general technical standards for the compression, decoding, processing, and the representation of digital audio-video, thereby enabling digital audio-video equipment and systems with high-efficiency and economical coding/decoding technologies. After more than ten years, AVS has established a series of video coding standards, including AVS1, AVS+ and AVS2. AVS1 and AVS2 are named from the first and second stage work of AVS, or the first and second generation standard, and AVS+ was established specially for China high definition TV broadcasting specially. AVS1 and AVS+ have been finished and widely used in various applications so far, and AVS2 is still under developing and will be released soon. This paper provides an overview of the history and recent developments of AVS video coding standards, including the key tools used in AVS and the comparison with the state-of-the-art technology, e.g. HEVC/H265. Moreover, a brief discussion and conclusion on the future video coding are provided.
