AVS编码性能研究
首发时间:2008-05-14
摘要:从编码结构,核心技术对我国拥有自主知识产权的音视频编解码标准AVS和国际标准H.264进行研究分析,并根据ITU-R BT.500描述的DSCQS视频主观评价方法,采用VQEG推荐的20个测试视频来评价这两大标准的编码性能,最后结合两大标准的核心技术特点对主观实验的结果进行了分析,目的是为AVS的发展推广提供一定的依据。

Research of AVS Coding Performance
Abstract:The audio and video standards AVS with independent intellectual property rights by our country and international standards H.264 are studied and analyzed in terms of their coding structure and core technologies. Their compression performances was estimated according to the DSCQS subjective assessment method which is described in the ITU-R BT.500 using 20 video materials recommended by VQEG, and the result was analyzed according to their core technologies. The purpose was to providing the basis for the application of AVS standards.
