AVS-M: Mobile video standard

Abstract

AVS-M standard is the seventh part of the standards developed by the Audio Video Coding Standard (AVS) Workgroup of China with focusing on video coding for mobility systems and devices with limited computation capability and power consumption. AVS-M standard can cover a broad range of applications including mobile multimedia broadcasting, IP multimedia subsystem (IMS), multimedia mailing, multimedia services over packet networks, video conferencing, video phone, and video surveillance. AVS Workgroup was authorized and established by Science and Technology Department under Ministry of Information Industry of China in June, 2002. To meet the requirement of information industry and realize the union of the native enterprises and research institutions, the mandate of the group is to establish (or edit) such general technical standards as the compression, decoding, processing, and the representation of digital audio-video and meanwhile provide the digital audio- video equipments and systems with high-efficient and economic coding/decoding technologies. This standard is applied in the field of significant information industry such as high-resolution digital broadcast, high-density laser-digital storage media, wireless broad-band multimedia communication, and internet broad-band stream media. The AVS standard is the series of "Information Technology Advanced Coding of Audio and Video" standard abbreviation. There are 10 parts of the AVS standard, as shown in Table 17.1. AVS-M standard is the seventh part of the AVS standard, which was finished by the group in 2006 [1]. The rest of this chapter will give an overview on AVS-M standard with being organized into the following five sections. Section 17.2 presents the overall architecture of AVS-M codec and its features. In Sect. 17.3, the structure and syntax of AVSMbitstream will be defined. Section 17.4 is devoted to the key techniques employed in AVS-M standard. Definitions of the profile and level used in AVS-M standard will be presented in Sect. 17.5. The last section will give some conclusions and further discussions on AVS-M standard with its applications and implementation. © 2009 Springer Science+Business Media, LLC.
