Abstract:

An intelligent transport system based on Digital Terrestrial Multimedia Broadcast(DTMB) is proposed, and its server system is implemented. Real-time traffic information of all styles is standardized, and encoded according to Transport Protocol Experts Group(TPEG) protocols. Information encoded is transferred into TS stream that can be transmitted through DTMB, the information is received by terminals with capability of receiving digital television after being sent through DTMB send system, terminal completes dynamic navigation using the information matched with static map. The prototype system validates the feasibility of the architecture.

Key words: intelligent navigation, digital television, Transport Protocol Experts Group(TPEG)
