Can you tell me the formula to figure the relative or approximate (since these things are dynamic) time/transfer? Such as, how long would a one hour show @ high quality take to upload assuming an upload rate of ~30K (or 256k upstream)? And the differences between the other qualities.


Sorry if this isn't worded right, but I'm no math major. I think you get the idea.

Remeber you can always multiply by 1...


assume 3GB for HQ show


times unit conversion (1024KB/GB)


divide by the transfer rate (30KB/s)


divide by another unit conversion (60s/minute)


divide by yet another unit conversion (60min/hour)


voila you should have your number in hours... (I don't have a calculator).



Note: It is unlikely that you will get the full upload rate from your service provider so scale that number appropriately.


Cheers

As an approximate rule of thumb
Code:

2266
#hrs for 1hr std =   -----------------
                     upstream bit rate

Multiply by 2 for medium


Multiply by 3 for high


This factors in 875MB/hr std and 90% of nominal upstream bit rate available

for actual data transfer (ie 10% overhead for headers and frames).

Thanks for the answers guys.

here is some math


if cbs says a show starts at 9:59 and runs untill 11:00 , and the show is only 45 mins long , how much more $ did they squeeze out of their sponcers?

I can't tell you how much they squeezed w/o knowing the show, but I

can tell you how much of the commercials I watched.
