Scalable and Personalised broadcast service

An aspect of the European IST SAVANT (Synchronised and Scalable Audio Visual content Across NeTworks) project is the personalisation of interactive TV systems combining broadcast programmes with additional content transmitted via the Internet. This paper describes scalability by selection of service components within the available services according to user preferences. This service adaptation is based on a developed metadata model. The personalisation techniques used in the first SAVANT prototype were demonstrated at IFA 2003 in Berlin, based on a news scenario. This demonstration showed content scalability by using a TV, a tablet PC and a PDA as display devices in addition to recommendations and personalisation by the selection of appropriate service components
