Personal television: A synchronized metadata system

Personal information consumption gets more and more important due to the huge amount of information available. In the Internet domain it is usual to create individual profiles e. g. on news portals to filter preferred categories. In this paper we present a personal TV system that realizes an automated selection and an assembly of news clips based on a synchronized metadata distribution via DVB in the broadcast domain. Furthermore, we introduce two possible scenarios for a practical realization based on synchronized metadata. We sketch up a prototypically developed system using DVB specifications for a synchronized transmission of metadata and an open source PVR library for the client implementation, which is also running on Linux set-top boxes. The head-end components for synchronized data insertion have been prototypically implemented for a flexible use in a playout environment.
