Dammit - I know we've been asked to stop this, but now something interesting has happened...
you found the beer ?
Richard, you, who I know has great experience in this, have posted figures that are UNDER my very basic but probably right theoretical minimums
How do you fit 3600 seconds at 128kbps into 46MB ? I get 56.25MB...
I have this ancient spreadsheet with a few assumptions.... I basically round 10bits to the byte to cover overheads in the packet, etc. So a data rate of say 128kbps is 12.8KB per sec or 0.13Mbps 768KB per minute or 7.68Mbps 46080 KB per hour or 460.9 Mbps or 46.08 MBytes per hour Remembering that you will get silence and various other things (outages, etc) it will always be an approximation. It just gives you a feel for the order of magnitude of the bill :-) Most stations actually have a second stream in reserve for special "promotional" occassions and they kick them into life every now and then, just to muck up the stats. The biggest use of it has been to work out that a 10GB plan is OK for radio stations at 32Kbps streams. Now that 40+GB plans are out, folks are looking at webcams again and it looks like we can stream a camera and stay inside a 40GB plan at 128k video, which isn't too bad looking. I should probably rework the spreadsheet for HD streams at 10Mbps. It looks like 5TB a month. And yes, IPV6 and multicast will solve all our problems, including world hunger and the endless shortage of beer. But I'm showing my age......
