摘要
提出一种基于数字电视国标(DTMB)的智能交通导航系统,并实现其服务器部分。规范不同来源和格式的实时交通信息,依据传输协议专家组协议完成对交通信息的实时编码,将编码后的信息转化为可通过DTMB无线传输的TS码流,通过现有的地面传输数字电视发射系统发射到终端,将实时交通信息与静态地图匹配,完成动态导航。
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 infomaation matched with static map. The prototype system validates the feasibility of the architecture.
