Request Based Telematics Contents Providing System using DMB

This paper describes a system for providing the telematics contents through DMB, according to the requests which are demanded by users. This paper includes the structure of the system which collects the messages requested by users, and makes the list of requests priority, and broadcasts telematics contents through the data channel on DMB. This system enables users to receive the requested telematics contents which are categorized by regions and services. Therefore, the proposed structures help users to receive the distinctive DMB data services. Moreover, the system can reduce the amount of each service data as the service vendors increase the bandwidth of the content requested frequently within the limited bandwidth by collecting and analyzing the requested contents.
