摘要
AVS(Audio Video Coding Standard)是由我国自主提出的第一个音视频编解码标准。在数字音视频系统的领域中主要有三种技术标准:MPEG4、H.264和AVS。国家视频标准(AVS)和国家地面数字电视标准(DMB-T)联合打造出了"双国标"的工程。目前,中国已经有很多的城市已经采用国标地面数字电视广播。该论文介绍了由我国自主提出的第一个最新视频编解码标准AVS,以及软件开发的流程,考虑到视频解码的环路滤波、1/4精度像素插值等典型运算量因素,并且在基于DSP的视频解码平台实现了AVS视频解码优化,在TI的CCS环境下进行了开发及测试,结果表明实现了优化并达到了实时解码效果。
AVS is China＇s first self-made audio and video codee standard. In the field of digital audio and video systems, there are three major technical standards： MPEG4, H.264 and AVS. National video standard （AVS） and national terrestrial digital TV standard （DMB-T） jointly create a ＂dual national standard ＂ of the project. At present, China has a lot of cities have adopted the national standard for terrestrial digital TV broadcasting. Self-made paper introduces the first of the latest video coding standard AVS, And the software development process, Taking into account the loop filter video decoder, 1 / 4 pixel interpolation, the typical accuracy of computation, And DSP-based platform of the AVS video decoder video decoder optimization, TI＇s CCS in the environment for the development and testing, The results show that the optimized and implemented to achieve real-time decoding results.
