Re: Cue the "USA Sucks" Whining!
You don't understand IPTV enough to know the differences. I liked playing with Sun's video delivery system while I was there , and it used IPtv , not multicasting. Which is why not many people bought it yet. Well accept the folks who purchased it to be used to store the content they needed to stream.
Multicasting the channel on ip is what cable co's want to use. Holding it at the edge is a buzz statement to try and solve a problem. This is a half assed attempt.
Iptv can only be streamed to 1 device at a time. If you have channel 100 streaming it takes another stream to hit me doubling the bandwidth used at the point of aggregation to the user. If we are on the same node we wasted a stream thus we wasted bandwidth that could be used by yet another victim of iptv. Multicasting avoids this. it lets the 2nd user pick up the stream as long as it's being broadcast already. IPtv as it stand does not allow this. It's actually considered a big security issue.
Cable multicasting is nothing new. What is new is they had the sense to see that they have to try and hold back unused channels. However just ask those folks in the beta regions. They are getting black screens with some cryptic messages on them. They did not plan on so many people wanting different channels.
Right now it's not ready for prime time. 1 way communications benefit from multicasting , it's just the way it is for now.
