A system which provides session oriented communications between a settop terminal and a headend of a CATV communication system assigns downstream and upstream communication paths to the communication. A data router monitors the downstream communication path and re-routes the downstream communication path when a channel change is requested by a subscriber. The settop terminal notifies the data router that a channel change has been requested by the subscriber. The router re-routes the downstream portion of the data communication to the new channel requested by the subscriber thereby insuring , an uninterrupted data communication session.

Why it's free to use
- Filed March 2, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 2, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 2, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
