Data Broadcasting Service Platform And Design To Achieve

With the development of Television Broadcast project, Digital Video Broadcasting (DVB) system becomes more and more widely adopted. It is possible to realize the data broadcast through DVB. To realize this possibility, We designed and realized a DVB data multicast service platform, and we implemented an application of distance learning through this platform.To provide the Multimedia broadcast service, It is necessary to have a Data Broadcast Service Platform which has flexible interface. This platform can provide data broadcast and media stream broadcast service, provide flexible application interface, have effective management of resource, and provide the security access service. To achieve those points, It must provide an universal platform to support data broadcast service in an optimal manner.In order to meet the need of data broadcast, we researched and analyzed the structure of multimedia data broadcast platform, we designed a model of this platform and realized this platform which supports the multimedia data broadcast service supports the management of resource and service, supports the flexible interface with application. This article focus on the research of the platform's interface, security access, line back, we made a little specify design on those area.At last, we implemented an application of distance learning on our Multimedia Data Broadcast Service Platform.
