Video Delivery on the Web
1) HTTP Downloading 2) Progressive Downloading – (Fast start, web streaming,
etc) 3) True Streaming
In General: If content is less than 1Mb in size (10 - 30 seconds of
video, depending on the encoding and the quality), downloading the video will not cause major slowdowns.
If content is over 5Mb in size (more than 5 - 8 minutes of video, depending on the encoding and the quality), true streaming is your best option.

Video Delivery on the Web
HTTP streaming – Downloading video from a web server The entire file is saved on your computer which you
then open and view. This has some advantages, such as not requiring a streaming server, but has the big disadvantage of having to wait for the whole file to download before any of it can be viewed.
HTTP streaming is not as efficient as true streaming and will incur a heavier server load.

Video Delivery on the Web
Progressive Downloading There is also a hybrid method known as progressive
download. In this method the video clip is downloaded but begins playing as soon as a portion of the file has been received. This simulates true streaming, but doesn't have all the advantages.

Video Delivery on the Web
Streaming Streaming media works a bit differently — the end
user can start watching the file almost as soon as it begins downloading. In effect, the file is sent to the user in a constant stream, and the user watches it as it arrives. The obvious advantage with this method is that no waiting is involved.
No files are downloaded to the viewer computer. The
content is delivered in small packets which are used for immediate playback & then discarded. At the end of the video clip, there are no traces of the content left on the viewers computer.
