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.
