Data and content based adaptation for video over low-bandwidth networks

Along with increased demand for access to distributed information and communication via the Internet, wireless PDA devices and cellular phones, there is a tremendous need for information providers to adapt to various user demands, not only in terms of the diversity of content, but also in how that content is delivered. The diversity of user, network and client capabilities often make traditional approaches such as the storage of multiple representations impractical. In the case of video, one of the primary considerations is the ability to provide content over low bandwidth and noisy networks as well as higher capacity networks. In this paper, we focus on novel techniques to adapt video for its delivery over IP. We provide insight into the existing problems and provide an overview of how our video analysis work is being applied in these areas.
