ITS 2000 ISTAG vision “Start creating an ambient intelligence landscape for seamless delivery of services and applications in Europe relying upon testbeds and open source software, develop user-friendliness, and develop and converge the networking infrastructure in Europe to world-class” EBU’s response: Develop a Public broadcasters’ strategy Encourage a ‘critical mass’ of service providers to support these objectives Advance in steps using existing infrastructure Invest heavily on improvements Expected return: The audience must increase! EBU aims at pan-European systems and services Action lines: TTI Strategy Team / Annual TTI Forum and Eurotravel Conferences
ITS 2000 Radio & TV
ITS 2000 Future needs of TTI service providers: -Delivering services with one or more higher bandwidth bearers, simultaneously -Generate messages once... -Multi-modal travel services needed... -Supply new services for sophisticated in- vehicle navigation systems … -Increased filtering for end-user needs … -Serve a wide range of radio receivers (Navigation systems, PDA’s, ….) Requirements
ITS 2000 Vision (1) Be bearer independent (byte oriented) Support language independent applications Permit multi-modal TTI, covering all forms of travel information Support a wide range of receiver/decoder types As much compatibility as possible with the ALERT-C protocol
ITS 2000 Vision (2) Use common forms of location referencing: WGS 84 (Long, Lat) & Road-intersections (text) The goal is that receiver/decoders may not need a location database in order to use information Have powerful service and network features: A TPEG stream may be a composite of services Each service could be a mixture of free and paid/encrypted sub-services
