Designing Ubiquitous Personalized TV-Anytime Services

In this paper we present the design of an environment that offers personalized, ubiquitous information services in the emerging integrated world of the digital-TV and the Internet. This environment is based on extended TV sets with a large capacity disk and Internet connection. We present an architecture that integrates external service providers that provide extended information services about broadcasts with powerful retrieval, personalization and ubiquitous access capabilities. We assume that the metadata information about the content of the TV programs follows the TV-anytime Forum Metadata (TVAM) specifications. The architecture allows content based matching and/or retrieval based on the description of the broadcast or parts of the broadcast according to the interests of the viewers. The viewer has access to his/her “personal channel” any time not only from home, but also while on move. It is obvious that due to communication, storage and processing limitations of handy devices, it is not possible to access normal digital-TV content. Thus, special mechanisms that filter and appropriately adapt the content are necessary, in order to meet user’s preferences and make its delivery and presentation feasible on the handy devices.
