Jonathan,
Thank you, as always.
So, if both parties are on broadband, they might well end up with the G.711
codec in use at a bit rate of 64 kbps.
I round that up to 3.9 Mb/minute (60 x 64k with 1024 b/kb), or 0.5 MB/minute
(3.9 Mb / 8 b/B). That means a 2 minute conversation in A/V could be 1 MB
of data? Am I close on this, or WAY out?
That would be 30 MB per hour which seems low given that you could sure
transfer a lot of data (as files) in that time.
If anyone reading this can control their laughter long enough to point out
my more significant errors, I would certainly be pleased for any further
feedback
Thanks,
Paul
Greetings Paul,
It's hard to say, Messenger actually can use a variety of codecs, and can
even dynamically
change codecs while in a voice/video conversation. See here:

Under 'Audio and Video Codec Availability' you can see the different
bitrates for each.

How can one determine a reasonable figure that would define the likely
bandwidth used in a 2-way A/V conference in MSN 6.
I am wondering if using it "a lot" (1 hour each day?) will put me over
my
ISPs limits for monthly bandwidth.
Thanks,
Paul
