<title>Streaming TPEG contents in the MPEG-4 system over DMB network</title>

Abstract

Telematics, a compound word with Telecommunications and Informatics, represents a kind of information service which provides traffic, public transport and emergency information to automobile drivers by using car navigation or other interactive communication system. In particular, as the DAB (Digital Audio Broadcasting) or DMB (Digital Multimedia Broadcasting) technology is introduced and commercialized, telematics is rapidly converging with various applications such as broadcasting and communication services. In this paper, we suggest an idea how a telematics service can be realized by DMB application which enables multimedia service operate on mobile devices. In order to achieve this goal, we generate multimedia content including TPEG (Transport Protocol Experts Group) contents which contain information about road and traffic. TPEG is an expert group which aims at defining a byte-oriented protocol for transport information broadcast. Transport information includes Road Traffic Messages, Public Transport Information and Location information which enables safe and efficient driving for drivers. In Europe, TPEG contents were delivered over DAB network which supports audio only broadcasting. We investigate the technique to deliver the multimedia content with TPEG content over DMB network so that we can provide the information in the scope of telematics as well as multimedia contents.
