TPEG supersedes TMC

Existing navigation devices are merely designed to guide their users as quickly as possible from A to B, but the next generation of digital assistants will offer a much wider range of services. They will provide users with seamless,up-to-date information, deliver reliable prognoses of traffic developments and offer additional features such as context-sensitive, location-based information. The new services, which are being developed at Fraunhofer First,are based on the TPEG (Transport Protocol Experts Group) coding standard.

The terrestrial-digital multimedia broadcasting(T-DMB) is now provided for the public service and the number of receivers reaches 15 million at the present of August 2008. The service of T-DMB itself has been succeeded in the presence. It is however remained as a supplementary role of stationed TV. It is necessary to find an additional business model as a new media to acquire surplus escaping from the deficit of the present T-DMB service. In the present paper, data service of T-DMB is proposed as candidate of such solution. Especially, TTI(Traffic and Travel Information) service is proposed as a killer application using TPEG(Transport Protocol Experts Group). At present, TPEG has not been so popular in the sense of various user satisfaction. Thus the variety of service including bi-directional service using DMB2.0 as in the sphere of Web2.0 is necessary for the service providers. In the paper, the restriction of TPEG-POI(Point of Interest) application service using the conventional mobile communication infrastructure is indicated. To overcome such restriction, TPEG-UCM(User Created Message) application service model using individual bi-directional media which is initiated and interacting by the users is proposed. In the experiment, the application program shows the usability of the proposed method so that the implementation results show its operability.

A novel TPEG application for location based service using terrestrial-DMB

This paper presents a new economic and effective TPEG (transport protocol experts group) application for location based service (LBS) that can be provided in terrestrial-digital multimedia broadcasting (T-DMB) transmission system. We propose a novel point-of-interest (POI) application interoperable with TPEG protocol, and introduce the POI data server/client and the DMB receiver with TPEG decoder implemented by using the proposed protocol. The stability and effectiveness of the proposed protocol is verified through the experimental broadcasting, and the pilot service using the commercial T-DMB network is being provided successfully.
