چکیده
We present an overview of on-going research, system design and middleware that has been implemented on top of a relational DBMS to provide advanced personalized information services in an integrated digital TV and Internet environment. The middleware provides automatic selection of programs or parts of programs based on users’ preferences. It is compatible to the TVAnytime Forum specifications for user and program metadata providing extended capabilities for information retrieval using the Extended Boolean model. Adaptation of preferences based on users’ viewing histories is also supported as well as the integration of domain specific ontologies to metadata standards. The metadata are managed robustly by a relational dbms allowing concurrency, remote access and modification. The system design and implementation emphasizes the use of standards (like TV-Anytime, MPEG-7, XML) for interfacing with the open outside world. Video is accessed based on its content and delivered in a variety of delivering channels including TVs, PCs, mobiles and PDAs.
