- The digital multimedia broadcasting (DMB) allows can provide an economical way of massive multimedia data services, thus, it is emerging as an optimal solution to address the several drawbacks of the mobile communication network. Among the data services based on the DMB, the traffic and travel Information (TTI) service has been spotlighted in aspects of economic influence and information usability. For example, the demand of TTI service has dramatically increased due to rapid increase in the number of vehicles and population of frequently traveling on long-weekends. In order to satisfying such a demanding, a transport protocol experts group (TPEG) protocol was developed. However, TPEG has been applied merely to two application areas up to now and there is no consideration to standardize new services very valuable for drivers and travelers. This paper presents new economic and effective point of interest (POI) and news services compatible to TPEG that can be provided in the DMB. To verify the stability of POI and news protocols, we implemented the TTI data server/client, and the DMB/DAB receiver with the TTI decoder. Through the experimental broadcasting in the local DMB network, it is shown that the proposed protocol operates stably and effectively in the navigation system. © 2006 SPIE-IS&T.
