As the file plays, it uses up information in the buffer, but while it is playing, more data is being downloaded. As long as the data can be downloaded as fast as it is used up in playback, the file will play smoothly. Usually there is a delay of only 10-30 seconds before the audio or video starts to play. Streamed files also don't require much bandwidth , so they can be played on computers that use modems to connect to the Internet. With streaming, learners can access lengthy pre-recorded audio and video clips to enhance and enrich their study of a topic.
Students can also watch or listen to a live event remotely.
In the case of distributed learning, streaming audio and video can serve as the primary mode of content delivery. These players are already installed on the computers in the CIT public labs, and can be downloaded for other computers. There are several technologies available for streaming files. Cornell Information Technologies is running a RealNetworks server, so if you use our server, you will need to use players and tools compatible with this technology. Streaming can be used to make audio and visual materials available to your students on the Web.
