Abstract:
Consuming mobile TV services is becoming increasingly popular. As hand held devices are personal and used in a â€œlean-forwardâ€ mode, they are well suited for interactive TV. The porTiVity system provides authoring tools for mobile interactive content that allow attaching interactivity to moving objectsin a TV program. We describe automatic and semi-automatic annotation tools that create content descriptions represented as MPEG-7 documents. The descriptions of moving objects are then transformed into MPEG-4 LASeR, which is a suitable lightweight format for visualization and interactivity on the mobile device. Since mobile devices are well suited for consuming personalized services we describe different personalization aspects. We show the use of the authoring components of porTiVity in two example scenarios.
