Abstract
The paper presents an MPEG-7 multimedia description schemes (MDS)-based metadata and user profile model used within an enhanced DTV environment for semantic annotation and personalized access to multiple sports DTV services. It is shown that in order to enable intelligent and personalized processing, management and use of multimedia content and services, the use of application specific metadata descriptions and adequately formulated user profiles is most important. Thus, application specific semantic metadata and user profile definitions are presented in this paper. Metadata and user profile instances are generated by authoring/annotation tools or user profile registration client applications respectively. Personalized access to sports DTV services is achieved by metadata and user profile instance description matching and content filtering at either the server or the client side. At the same time, dynamic client configuration, transparent to the end-user, is accomplished by automatically processing configuration specific metadata descriptions using specially designed application modules at the client side. The main purpose is to enable personalized integrated multimedia services access in the sports domain over DTV infrastructures
