该文是中国多媒体技术研究与应用的年度文献综述之十。该文从发表在2007年9种国内核心刊物上的3 034篇论文中，选取了516篇与多媒体技术相关的文章进行了分类、统计，以展现2007年中国多媒体技术发展的现状。今年的分类标准做了一些调整，据此选取的论文能更集中地反映出多媒体技术研究的概貌。通过与前4年的统计结果进行对比可以看出，数字水印、虚拟现实、多媒体数据检索、多播、流媒体、交互模式与接口、生物特征身份识别等是2007年论文反映出的研究热点，同时，多媒体应用日趋多样化，并和社会生活的结合程度越来越紧密。该文还对5年来中国多媒体技术文献统计结果进行了比较，从中可清楚地看到多媒体技术，特别是一些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系统的文献索引，也能为技术规划和管理人员提供参考。

As one of a serial of reports, this paper is a survey on multimedia researches and applications in China, 2007. Since multimedia is a cross research area, papers about multimedia technology are distributed on various journals. We checked 3 034 papers published on 9 Chinese journals in 2007, from which we have selected 516 related to multimedia technology and applications. Then we made analysis on them and the statistics were compared with those from 2003 to 2006. The catagories have been modified to make the papers selected focus more on multimedia researches. Looking into the data, we can find that digital watermarking, virtual reality, multimedia data retrieval, multicast, streaming media, interactive mode and interface, identification using biometrics 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, 2007. This article can be used by researchers as a thoroughly references, and also will be helpful for people in technical planning and management.
