Information-theoretic research of video coding: theory and algorithms

视频通信是当今和未来工程领域的一个主要增长领域。只要看看互联网电视、互联网视频会议和移动的视频的日益普及就知道了。然而，视频通信中的一个关键问题是视频数据量的不断增长与带宽日益短缺之间的矛盾。这在无线视频通信中尤其如此。事实上，随着无线视频的日益普及以及高清电视和其他新兴视频应用的激增，带宽短缺变得越来越严重，以至于它被视为值得我们国家关注的问题。因此，强烈需要更好的视频编码技术，其可以显著提高压缩效率，同时提供其他绿色特征，例如低复杂度（因此低编码和解码功耗）和可伸缩性。

Video communications is a major area of growth in engineering today and in the future. Just look at the growing popularity of Internet TV, Internet video conferencing, and mobile video. A key problem in video communications, however, is the conflict between the growing data volume of video and the increasing shortage of bandwidth. This is particularly true in wireless video communications. Indeed, with the growing popularity of wireless video and the proliferation of high definition TV and other emerging new video applications, the bandwidth shortage becomes increasingly severe to the extent that it is regarded as an issue meriting our national attention. As such, there is strong demand for better video coding technologies which can improve compression efficiency significantly while providing other green features such as low complexity (hence low encoding and decoding power consumption) and scalability.
