Streaming servers provide streaming in UDP Protocol and HTTP Protocol when the end user is unable to accept UDP Protocol streaming. Web servers can only playback using HTTP Protocol. It's really quite simple. Thus, a pixel of blue sky or a pixel of brown dirt may be missing in one of the frames, but the movie will play regardless. HTTP is all about accounting.
Web servers are unable to manage SMIL content.
To estimate how much disk space your streaming media will take up at different rates, you can simply use our handy, streaming calculator . Take the kilobits per second and divide by 8. Take this number and multiply by 60 so you will have the kilobytes per minute. Multiply this by the length of your media in minutes. This number will probably be at least four digits.
