| Abstract: | With the development of digital broadcasting, application area of digital broadcasting is becoming even broader. A multi-service integrated data broadcast system on DVB-S channel is presented in this paper. System provides four basic services: digital TV, stream media, file and message. Customers can extend any applications based on these basic services. System architecture and transmission protocol are described, and transmission performance is analyzed. The main factors that affect performance of the syst... |
