Abstract :
We had indicated multimedia communication services, which can provide multimedia information according to functionality and availability for users. We had already proposed “Multimedia Scalability Package: MSP” as data structure in integrated multimedia services. In this paper, we proposed a distance education system based on MSP data communication as one of MSP multimedia services. We especially considered this system using proceedings data and video contents. The structuring methods of data architecture are used scalability. We had studied description schemes in MSP data, such as, header information and behavior information of content data for tele-lecturing system. It is needed to update mode data, which could control remote play and MSP data access in user side. That´s because we send only control data in the case of remote control, any network environment is available, such as, wide band, narrow band and wireless network. In this system, to decode MSP data realized a virtual tele-lecturing system between presenter´s and users´ terminals. Moreover, overview of this system was shown. MSP data has been previously transmitted to data repository in users´ terminals. They are points that it uses information key as manipulation of lecture data, and that this key simultaneously works all data. For example, when lecture´s data has contents scalability of abstract data, data for 3 minutes and full data for 10 minutes, level information controls to play contents. Finally, this system architecture was indicated, and procedure of MSP data and MSP data structure were explained and were simulated. So it was shown that this system was available as tele-lectures.
