# IVS transfer time

How long could it take to send or receive a one hour program? A show
sent to a friend took 2hr 30 minutes at 28Kb/Sec (using the DVR
Network Meter). A show from him is coming to me at 8Kb to 5Kb/sec. It
could take 48Hr. Both of use are on the same cable TV ISP.

Transfer speed depends on the SLOWEST of the receiver's download speed
and the sender's upload speed (rather obvious, but ignored?). Because
of the way internet connection speeds are, it's usually the sender who
limits it. Having a really high download speed won't help here (it
would if you're downloading from A/V newsgroups, one reason I was
recommending them).

Notice that the network meter shows KB/sec (kiloBYTES per second) not
Kb/sec (kiloBITS per second). Software often uses KB/sec. Internet
connections are normally rated in Kb/sec. This seems to often get
people confused.

28KB/sec = 224Kb/sec (what you're likely to get with an internet
connection advertised as 256Kb/sec).

The size of the file depends on the quality setting. At standard, it's
about 850MB/hour, twice that with medium, 3 times with high.

Then, a 1-hour file contains about 6.7Gb (850MB * 8 bits in a byte).

That internet connection will allow you to send 224Kb (that's 28KB)
per second, so the transfer should take about 31,086 seconds. That's
518 minutes (8 hours, 38 minutes, 6 seconds). It will take even more
time if the internet connection is being used for anything else.

Medium qualtiy would double that time. High would triple it.

A standard quality 1 hour show typically takes about 10 hours. Even with
cable/dsl, the upload speed is usually limited.
