Über dieses Buch

The requirements for multimedia (especially video and audio) communications increase rapidly in the last two decades in broad areas such as television, entertainment, interactive services, telecommunications, conference, medicine, security, business, traffic, defense and banking. Video and audio coding standards play most important roles in multimedia communications. In order to meet these requirements, series of video and audio coding standards have been developed such as MPEG-2, MPEG-4, MPEG-21 for audio and video by ISO/IEC, H.26x for video and G.72x for audio by ITU-T, Video Coder 1 (VC-1) for video by the Society of Motion Picture and Television Engineers (SMPTE) and RealVideo (RV) 9 for video by Real Networks.

AVS China is the abbreviation for Audio Video Coding Standard of China. This new standard includes four main technical areas, which are systems, video, audio and digital copyright management (DRM), and some supporting documents such as consistency verification. The second part of the standard known as AVS1-P2 (Video - Jizhun) was approved as the national standard of China in 2006, and several final drafts of the standard have been completed, including AVS1-P1 (System - Broadcast), AVS1-P2 (Video - Zengqiang), AVS1-P3 (Audio - Double track), AVS1-P3 (Audio - 5.1), AVS1-P7 (Mobile Video), AVS-S-P2 (Video) and AVS-S-P3 (Audio). AVS China provides a technical solution for many applications such as digital broadcasting (SDTV and HDTV), high-density storage media, Internet streaming media, and will be used in the domestic IPTV, satellite and possibly the cable TV market. Comparing with other coding standards such as H.264 AVC, the advantages of AVS video standard include similar performance, lower complexity, lower implementation cost and licensing fees. This standard has attracted great deal of attention from industries related to television, multimedia communications and even chip manufacturing from around the world. Also many well known companies have joined the AVS Group to be Full Members or Observing Members. The 163 members of AVS Group include Texas Instruments (TI) Co., Agilent Technologies Co. Ltd., Envivio Inc., NDS, Philips Research East Asia, Aisino Corporation, LG, Alcatel Shanghai Bell Co. Ltd., Nokia (China) Investment (NCIC) Co. Ltd., Sony (China) Ltd., and Toshiba (China) Co. Ltd. as well as some high level universities in China. Thus there is a pressing need from the instructors, students, and engineers for a book dealing with the topic of AVS China and its performance comparisons with similar standards such as H.264, VC-1 and RV-9.

Chapter 1. Introduction
Abstract
A brief description (comparison) of various video/image coding standards such as JPEG, MPEG and H.26x series besides, DIRAC (Chap.​ 7), AVS China (Chap. 3) and VC-1 (Chap. 8) are presented. Similarly brief description on audio coding followed by comparison metrics concludes the chapter.
K. R. Rao, Do Nyeon Kim, Jae Jeong Hwang
Chapter 2. Video Coding Standards and Video Formats
Abstract
Video formats, conversions among RGB, Y, Cb, Cr, and YUV are presented. These are basically continuation from Chap.​ 1 and thus complement the topics discussed in Chap.​ 1.
K. R. Rao, Do Nyeon Kim, Jae Jeong Hwang
Chapter 3. AVS China
Abstract
Audio and video standard (AVS) of China is described in detail. Profile, levels and functionalities inherent in encoder and decoder are addressed. The codec is similar to H.264/AVC (Chap.​ 4) with simpler options resulting in reduced implementation complexity at the cost of negligible loss in performance. Details on AVS system and adoption of AVS China as an IEEE standard are presented.
K. R. Rao, Do Nyeon Kim, Jae Jeong Hwang
Chapter 4. H.264/MPEG-4 Advanced Video Coding
Abstract
Similar to AVS China (Chap.​ 3), the profiles, levels and functionalities of H.264/AVC are described. The roles of various blocks in the encoder and decoder, from a video compression view point, are addressed. The similarities and differences between AVS China and H.264/AVC can be observed.
K. R. Rao, Do Nyeon Kim, Jae Jeong Hwang
Chapter 5. High Efficiency Video Coding(HEVC)
Abstract
HEVC the latest standard is presented. Comparison with H.264/AVC (Chap.​ 4) is cited. The focus is on overview of HEVC rather than a detailed description of tools and techniques that constitute the encoder. A plethora of projects listed at the end challenges the implementation and futher research related to HEVC.
K. R. Rao, Do Nyeon Kim, Jae Jeong Hwang
Chapter 6. VP6 Video Coding Standard
Abstract
Encoder/decoder details on VP6 developed by On2 Technologies are provided. Similarities related to functionalities between H.264 (Chap.​ 4) and VP6 are highlighted and differences such as golden frames are pointed out. Resources related to VP9 open source video codec by Google (Google acquired On2 Technologies in 2010) are also addressed.
K. R. Rao, Do Nyeon Kim, Jae Jeong Hwang
Chapter 7. Performance Analysis and Comparison of the Dirac Video Codec with H.264/MPEG-4, Part 10
Abstract
Dirac video codec developed by BBC deviates from other standards as wavelet transform instead of INTDCTs is adopted. Pros and cons of wavelet transform are listed. Besides encoder details of Dirac, its performance comparison with H.264/AVC using several test sequences based on mse/PSNR, bit rates and SSIM is provided.
K. R. Rao, Do Nyeon Kim, Jae Jeong Hwang
Chapter 8. The VC-1 Video Coding
Abstract
As with other codecs, encoder/decoder details on VC-1 are described. VC-1 is an SMPTE standard based on WMV9 developed by Microsoft. H.264/AVC to VC-1 transcoder is outlined. The intra frame coding only of Dirac (Chap.​ 7) is adopted by SMPTE as VC-2.
