Abstract
An access node (e.g., DSLAM) is described herein which can limit bandwidth usage in a transport network by incorporating an enhanced rapid TV channel changing functionality/enhanced BTV server in which TV channels from a multicast TV stream are dynamically selected based on past TV channel clicking statistics and then stored therein so there is a good chance that it can respond to a TV channel change request from a STB.
