中国多媒体技术研究：2009

本文是中国多媒体技术研究与应用的年度文献综述之十二。该文从2009年9种核心刊物的3023篇中选取396篇多媒体技术相关的文章进行了分类、统计，以展现出2009年中国多媒体技术发展的现状。今年采用的分类方案在去年的基础上做了一些调整，以适应多媒体技术发展的趋势。通过与前4年统计结果的对比可以看出，数字水印、数据管理与检索、多播、交互模式与接口、虚拟现实交互等多媒体基础技术是2009年论文反映出的研究热点，同时，多媒体应用日趋多样化，与社会生活的结合程度越来越紧密。该文还对近5年的中国多媒体技术文献统计结果作了比较，从中可看到多媒体技术，特别是一些热点技术的发展趋势。该文不仅能给从事多媒体技术研究与应用的人员提供系统的文献索引，也能为技术规划和管理人员提供参考。

Researches on Multimedia Technology in China, 2009

As one of a serial of reports, this paper is a survey on multimedia researches and applications in China, 2009. Since multimedia is a cross research area, papers about multimedia technology are distributed on various journals. We checked 3023 papers published on 9 Chinese journals in 2009, from which we have selected 396 related to multimedia technology and application. Then we made analysis on them and the statistics were compared with those from 2005 to 2008. Considering the new feature of multimedia technology, we make serveral modifications to the categories of the papers for this year in order that the new categories can reflect the situation of multimedia technology in 2009 better and match its developing trend more exactly. Looking into the data, we can find that digital watermarking, multimedia data management and retrieval, multicast, interactive mode and interface, virtual reality interaction earn high attention of researchers in China. Meanwhile, multimedia application systems are diversified and intergraded with daily life gradually. We present here an overview on the progress in multimedia technology in China, 2009. This article can be used by researchers as a thoroughly references, and also will be helpful for people in technical planning and management.
