摘要
基于数字电视地面广播(Digital Television Terrestrial Multimedia Broadcasting,DTMB)传输体制设计实现了面向多业务的嵌入式接收终端的软件系统。该嵌入式接收终端软件,基于DTMB标准,兼容具体设计的简化多业务传输流(Transport Stream,TS)复用协议,可实现多业务数据解析与处理,包括视频数据、短信息和传感器数据。多线程和模块化的设计保证了接收终端软件系统的实时性与灵活性。测试结果表明,文中实现的多业务接收终端软件可完成音视频的接收与播放、短消息数据业务和传感器数据的实时接收与显示。
Exploiting digital television terrestrial multimedia broadcasting （DTMB） standard, a software system for DVB embedded receiver for multi-services is designed and implemented. The software system, which is devised for the specific and simplified multi-services transport stream （TS） multiplexing protocol, enables the analysis and processing of multi-services including the video, messages and sensor data. The design of muhithread and modular ensures the real-time and flexibility of the receiving terminal software system. Testing shows that the developed software for multi-services embedded receiver is able to accomplish the real-time receiving of the audio/video, short messages and the sensor data.
