In spite of Verizon's incessantly exhorting us to get FiOS, I'm still hanging
on with ADSL. In our case, I can usually coax the modem to get a decent ATM
link, so that my measured IP bit rate is around 1.83 Mb/s, or occasionally up
to 2.17 Mb/s, downstream.
We've had no trouble with Skype, and I use this method to watch all of my prime
time TV these days. Sometimes I'm streaming TV downstairs, while my wife is
doing the same thing upstairs (different program -- not that this matters, as
each session is unicast regardless).
Here's what I did notice, though.
Yes, there are times when the picture stops while my WiFi USB stick is
frantically downloading data. But how clever are these guys? This almost
exclusively happens during commercial breaks. It turns out that the streaming
protocol pre-loads much or perhaps all of the next program segment, during ad
breaks. So if anyone has trouble out there, check to see if the same might not
be happening to you. Some ads are worse than others, but almost always, the
actual program streams just fine.
This may also explain why many ads appear to be lower res than the program
itself. While the ad is streaming, the server is simultaneously pre-loading the
next program segment.
