In this paper we present a framework for eRicient representation, access, and manipulation of video data. Our approach is based on decomposing video information into its spatial (appearance), temporal (dynamics), geometric components. This derived information is organized into data representations that support non-linear browsing and efficient indexing to provide rapid access directly to the in...

The network market shows a hierarchy of providers, with backbone providers and access providers. We aim in this paper at describing the economic relationships between those network providers, where content providers are associated to backbone providers while access providers compete to attract end users. We study those interactions thanks to game theory, using a multi-level game model. We analy...
