If it is the same thing your talking about.
Phone lines can only carry so much bandwidth...about 3 digital channels...... so when you press your remote control to change a channel you activate a signal that switches at the C.O. (so you can watch many different channels) to a different channel.....so in your house you can watch 3 different channels at a time on three different T.V.s
> Can someone explain to me the technology of switched digital video? Who is the content provider? We are looking at a FTTH overbuild and do not want to 'throw away' our analog headend, but it looks like SDV would be the way to go for VOD and interactive tv/gaming.
