Streaming technique and its application in distance learning system

In this paper, streaming technique and its application in distance learning system are discussed. By using this new technique, people can distribute continuous media information over Internet without requiring downloading it first, which means that you can play it while you downloading it. This property is very useful in Internet environment because the bandwidth is not wide enough and much time are needed to download a multimedia file, such MPEG video/audio files. As we know, distance-learning system is a typical multimedia application system. It involves in many kinds of information media, for example, video, audio, graphic and text. The outstanding property of distance learning system is that these media information are not independent, they have temporal and spatial relationship to some extent. After transmitted through the network, how to keep the synchronization relationship of these media information is the central issue in distance learning system. In this article, we will also discuss how to keep media synchronization by using streaming technique.
