Streaming Media

Video streaming allows the viewer to watch a video file or listen to an audio file over the World Wide Web without waiting for the file to download to the desktop computer. In 1996, Mississippi State University streamed its first video and today there are a variety of videos, meetings, and live performances that are streamed by Mississippi State University.

To rescue the user from a long download time of video files, video streaming provides an excellent alternative. The user can begin watching a video or audio file while the file is being sent. The file is sent in a gradual continuous stream to the desktop computer and not downloaded onto the desktop computer. The wait time is limited for video streaming (depending on the strength of the Internet connection).
