| Abstract: | The Digital Video Broadcasting-Satellite(DVB-S) data broadcasting system is a popularized,open standard and cost-effective wide-band satellite broadcast system.It can fully cover meteorological broadcast services such as data and audio/video transmission.The basic scheme of DVB-S data broadcasting system is introduced,and its application models in meteorological services are discussed based on the general requirements and technical scheme of the next generation meteorological data broadcast system and the implementation of the experimentation system.It is concluded that the DVB-S based the satellite data broadcasting system will highly upgrade the data distribution and service level of the National Meteorological Information Center.It is a very important mission to investigate the application models and extend the service area of DVB-S technology. |
