该文是中国多媒体技术研究与应用的年度文献综述之八。该文通过查阅2005年9种核心刊物的3097篇文章，从中选取了410篇与多媒体技术相关的文章，并进行了分类、统计，以展现出2005年中国多媒体技术发展的现状。同时，通过前四年统计结果的对比可以看到，数字水印、虚拟现实、多模态接口、普适计算环境、多媒体信息检索、服务质量保证、计算机支持的协同工作、地理信息系统和数字地球等这些国际上的多媒体热点研究课题在中国也受到了高度的重视。该文还对5年来多媒体技术文献统计结果做了比较，从中可清楚地看到多媒体技术，尤其是该领域热点技术的发展过程和发展趋势。希望该文不仅能给从事多媒体技术研究与应用的人员提供一个系统的文献资料索引，也能为探索研究方向提供参考。

This paper is the eight annual survey on multimedia researches and applications in China, 2005. Since multimedia is a cross-field research area, papers about multimedia technology are scattered over various journals. We checked about 3097 papers published on 9 Chinese journals in 2005, from which we picked up 410 related to multimedia technology and application. Then we made analysis and statistics on them comparing with data from 2001 to 2004. Looking through the data we can find that researchers in China have been continuously paying more and more attention to digital watermarking, virtual reality, muhimodal interface, infrastructure of pervasive computing, multimedia information retrieval technology, quality of service, computer supported cooperative work, GIS and digital earth, which are also the worldwide trends for a quite long period. We present here an overview on the progress in multimedia technology in China, 2005. This article tries to help the researchers not only in looking for references, but also in exploring the new direction of research.
