数字音视频编解码标准(AVS)是中国自主制订的数字电视、IPTV等音视频系统的基础性标准。AVS标准第2部分视频(AVS1-P2)属高效的第二代视频编码技术,相比于第一代标准MPEG-2。编码效率提高2—3倍,并且实现方案简洁,因此,AVS视频标准已经为IPTV,数字电视厂播等应用做好了充分的技术准备。同时,AVS标准具有专利许可方式简洁、相关标准配套的优势。这将为中国的IPTV、数字电视广播等重大信息产业应用及民族IT产业发展起到积极的推动作用。
Audio Video coding Standard (AVS), independently developed and owned by China, is a fundamental standard applied in digital TV, IPTV and other audio/video based systems. AVS Part 2 (AVS1-P2), the video part, defines the highly efficient second generation video coding technology, with the coding efficiency 2-3 times higher than the first generation standard like MPEG-2. Moreover, its implementation is simple and easy. Therefore, AVS1-P2 has made full technical preparation for such applications as IPTV and digital TV broadcast. Meanwhile, AVS possesses the advantages of simple intellectual property warranty and cooperative standards support. It will effectively push the development of national IT industry of China and its important information applications like IPTV and digital TV broadcast.
