Just a small study I did about streaming video and quality.
Ted talk quality, for eg.
www.ted.com/talks/ken_ robinson_says_schools_kill_ creativity.html
- wireshark clocked it at 0.415 Mbps - let's say 400 kbps.
(Ted uses variable bit rate streaming - bitrate changes with scene as well as with bandwidth availability)
Youtube video at 360p -
http://www.youtube.com/watch? v=I1Tbn1GtIGE&feature=grec_ index
21.6 MB for 8 minutes 45 sec
21.6 MB/525 seconds
= 0.0411 MB/s
= 0.329 Mbps, close to 300 kbps.
But these are all offline encoded videos. For live encoder, quality will be somewhat lower for the same bitrates.
