Overview of AVS Video Standard 2004 IEEE International Conference on Multimedia and Expo (ICME)
Abstract This paper overviews the AVS video standard in terms of basic features, adopted major techniques and its pegormancr. The current version of AVS video standard mainly aims at the idcreasing demand on high definition and high quality video services. It provides a good trade-off solution berween complexity and coding eficiency for digital broadcasi and digital storage media. Funhermore, similar to the syntax structure in MPEG-2 video standard, it can be easily applied into the exrensively existing MPEG-2 systems while significantly improving coding eficiency.1. Introduction AVS video standard is developed by the Audio Video Coding Standard Working Group of China (AVS working group in short), which was approved by the Chinese Science and Technology Department of Ministry of Information Industry in June 2002. The mandate of the AVS working group is to establish the China's national standards for compression, manipulation and digital right management in digital audio and video multimedia equipment and systems. AVS working group has finished the first version of AVS video standard in December 2003 [I],an d expects to be approved as a national standard in 2004. This version mainly targets at high definition and high quality digital broadcasting, digital storage media and other related applications. It can be also applied in existing standard definition applications. This paper is organized as follows. Section 2 introduces the basic architecture of AVS video codec and its features. Section 3 describes some key techniques adopted in AVS video standard. Section 4 explains the profile and the levels defined in the current AVS video specification. Finally, the experimental results are given in Section 5.
