Video Streaming at WSU
From wsuwiki
There are many ways to deal with the delivery of video over IP networks. The most popular of these methods are burst http, such as used with Podcasting and progressive downloading, or streaming for real-time delivery of video.
Progressive Downloading:
Using this method is usually preferred for high speed networks and smaller/shorter/high quality video files, however this method can also be used for delivery of high quality video files to locations with a smaller internet pipe, it just takes longer for delivery. Video files are downloaded to the client machine where it is locally archived onto the hard disk for viewing at the user’s convenience often for multiple views. This method can be used with any codec (stands for compression-decompression, Windows Media, Quicktime, Real Video, and MPEG are all codecs.) This method of delivery is not to be confused with streaming. To deliver progressive downloaded video all that is required is your video file and a web server. When hosting downloadable video on your web server be prepared to see a great increase in demand on bandwidth once your file is posted.
Streaming:
Streaming refers to the real-time delivery of video. Streaming requires special software for delivery both at the server and the client. Some server software can be quite specialized and very expensive in both purchase and/or upkeep, however most client software is available for free. Streaming must be used with a codec that supports the real-time delivery of content, such as the rtp, rtsp, or mms protocols, please note that some codecs do not allow for this. Streaming video can be very high in quality, however it is highly limited by bandwidth. The higher the quality of video, the more bandwidth is required, however quality can be adjusted to fit the needs of bandwidth.
Educational and Public Media, or EPM, on the WSU-Pullman campus supports IP video for most WSU events and entities. Our main portal is located at http://experience.wsu.edu. If you require support or have any questions regarding high quality encoding or hosting of IP video call EPM at 509-335-6504 or email us at videostreaming@wsu.edu.
Video Streaming servers are managed by a number of WSU entities, including Educational and Public Media(<http://www.epm.wsu.edu/>), and probably others (try www.wsu.edu, then search on "streaming"). You may be able to use one of these services (depending on their rules, etc...)

Thanks. I do not know the files sizes yet. I was just told in anticipation of this request. This is good to know though. I was not sure if I had to stream or just link to a file much like a .PDF. I assume that, by using this method, the file will then be played by whatever the default player is for that computer, correct? Also, will this method still work for larger file sizes? What limitations am I looking at? My purpose here is to gather information to enlighten these people once we meet for the propose design of this website. Thanks again for the assistance.

If they're not too large, don't worry about streaming. Just convert them to MPEG format and place them on your web server.
