An Open Architecture and Realization for the Integration of Broadcast Digital Video and Personalized Online Media

With the introduction of digital broadcast, e.g. DVB, the question arise which kind of new interactive services can be offered to the viewer. Until now, these services concentrate on EPGs, video on demand, and basic E-Commerce services presented on TV sets. On the other side new generation TV sets are able to access the Internet and to present WWW content. — One aim of this paper is the presentation of an new architecture which allows the genuine combination of broadcast and Internet content, allowing the creation and use of hyperlinked interactive video. Adding hypermedia capabilities to objects inside video streams opens the opportunity for new kinds of synchronized content presentations with a wide variety of applications. — A main requirement which is fulfilled by the proposed architecture is the support of existing or upcoming formats and delivery channels and to be open for further developments and applications. For hyperlinked digital video we present a concept which consists of three independent components: the video content, the specification of selectable objects and the linking information. Furthermore, the system consists of a client-server architecture which allows global interaction. Based on this separated components the system is open for customizations and the introduction of personalization. — Personalization allows the filtering and adaptation of content based on device and user profiles. With this methods, different presentation devices can be supported, ranging from small, restricted mobile appliances up to large screen stationary presentation equipment and, furthermore, the consideration of user preferences. — The client-server concept and the adaptable components allow the application of hyperlinked interactive video in pure Internet environments, e.g. the WWW, and in broadcast environments with different realizations of a return channel.
