Abstract
This paper presents a framework for object based interactivity in digital video broadcast (DVB) television systems. Based upon pre-recorded MPEG-2 video material an object annotation and synchronization scheme has been designed and implemented enabling the viewer to actively interact on previously marked video objects. The framework comprises an authoring process which extracts the necessary Meta data the introduction of a new timeline in the transport stream and the synchronization process at the client site. To show its feasibility at the client site the MHP platform was used. Obtained results of various content samples indicate that our approach is promising and effective thus offering new service models such as e.g. automatic in-program content placements
