Streaming technique and its application in distance learning system

A streaming technique and its application in distance learning system are discussed. By using this new technique, people can distribute continuous media information over the Internet without downloading it first, which means that you can play it while you downloading it. This property is very useful in the 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, a 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 the distance learning system is that these media information are not independent, they have temporal and spatial relationship to some extent. After transmission through the network, how to keep the synchronization relationship of these media information is the central issue in the distance learning system. In this article, we will also discuss how to keep media synchronization by using streaming technique
