先进视音频编码技术论坛（03.10.09,杭州）通知
背景：
数字音视频产业是电子信息产业的重要组成部分，主要包括数字电视、激光视盘机、音频设备等产品，其产值约占信息产业产值的三分之一，“十五”期间将迅速成长为累计值超过万亿元的大产业。音视频编码压缩技术是包括数字电视和高密度激光视盘在内的数字音视频产业的基础共性技术，我国有一定的研究开发工作积累和相应的技术储备，是制定重大技术标准的一个很好的突破口。如果掌握了音视频编解码技术并将其标准化，不仅标志着我国在多媒体处理等领域的研究处于国际领先地位，还将创造可观的经济效益和社会效益。
我国从90年代就开始参与跟踪国际标准的制定，1996年，以高文教授为团长的MPEG中国代表团开始参加国际标准的制定；自2000年以来，国内多家单位的提案在MPEG-4、JVT专家组中得到采纳。这些都为我国自主知识产权的音视频编解码标准的制定奠定了基础。
2002年6月，信息产业部批准成立 “数字音视频编解码技术标准工作组”（AVS工作组），目前参加工作组的单位已达50家，覆盖了国内本领域的主要产品开发生产厂家与研究单位，也包括跨国企业与机构。工作组已经召开五次工作会议，提出了标准草案和验证软件。“所测AVS音视频编解码（软件）系统在压缩码率比MPEG-2编解码系统低一倍的情况下，图像质量均好于经MPEG-2编解码后的图像质量”。2003年7月12 日，受信息产业部科技司、科技部高新司和中科院高技术局的委托，中国工程院信息与电子工程学部召开了数字音视频编解码技术（AVS）评估会议，包括10名院士在内的23名专家组成了评估委员会，委员们认为：AVS的产业化可以节省相当可观的MPEG-2专利费，压缩效率比MPEG-2高一倍，节省信道资源和光盘存储资源，为我国数字电视等音视频产业和相关芯片产业提供跨越发展的技术源头。
借AVS工作组在杭召开第六次会议之机，举行本次论坛，希望在国家和地方政府各部门的指导下，在产业和学术界的广泛参与下，解决我国数字音视频芯片、软件、设备与系统所需要的共性核心技术，制定数字音视频领域的关键技术标准，推动数字电视、高密度激光视盘机设备、宽带多媒体应用和第三代移动通信等数字音视频相关产业的跨越发展。

论坛人员介绍
高文，教授 博士生导师，全国政协委员。
1956年出生于大连。1988年获哈尔滨工业大学计算机应用博士学位，1991年获日本东京大学电子学博士学位，现任中国科学院研究生院常务副院长，中国科学院计算技术研究所研究员，哈尔滨工业大学教授。高文教授曾在日本东京大学医学电子学研究所，美国卡内基梅隆大学(CMU)机器人研究所，美国麻省理工学院(MIT)人工智能实验室等做客座研究员。他1992年入选进入国家863专家组，从1996年至2000年任国家863计划智能计算机主题专家组组长(首席专家)。高文教授目前还兼任计算机学报主编，中国图像图形学会副理事长，中国软件行业协会副理事长，信息产业部AVS工作组组长。他是国务院学位委员会计算机学科评议组成员，是ISO/IEC/JTC1/SC29/MPEG国际标准化委员会中国代表团团长，是IEEE视频信号处理和通信技术委员会委员(VSPC)。
Dr. Reader received his B. Eng. Degree from University of Liverpool,
England (1970) and his PH.D. degree from the University of Sussex England
(1974). His thesis topic was Coding of Still and Moving Pictures, and concerned
both block-adaptive transform coding and the first application of block
transform coding to video. Most of the doctorate work was performed in
residence at the University of Southern California Image Processing Institute.
A focus of this work was to find practical, cost-effective ways of implementing
the algorithms, and this skill was developed further in his working career,
when he specified and architected systems and chips for real-time image
processing and display systems, and more recently digital video systems. He has
worked in reconnaissance and other military imaging systems, including early
work in 3D modeling for mission planning (~1979), and in medical imaging systems,
including early work in 3D imaging for reconstructive surgery (~1987). The work
involved both interfacing with customers to develop product specifications, and
leading the product design effort itself. In more recent years he has focused
on business development, developing strategic partnerships and licensing
agreements for media processor products, and developing a sales plan for
integrating MPEG encoding, Dolby Digital encoding and DVD authoring into the
first turnkey Windows NT solution. He led the sales team for this product,
multiplying sales revenue by a factor of five in three quarters and reaching
break-even point. In the last few years, he was VP Sales and Marketing for
nDSP, a company selling advanced display chips to TV and DVD manufacturers in
China. He ramped sales to an annual rate of $3.5M per year before the company
was sold. He is currently consulting to a number of major US corporations and
to the Chinese Academy of Sciences. Dr. Reader has been active in MPEG since
1990, holding the positions of US Head of Delegation (1991-1992), and Chairman
of the MPEG4 subcommittee (1993-1996) among others. He was the technical expert
for CableLabs in setting up the MPEG patent pool, and has published numerous
papers in the field.
