Virtual Channel Management for IPTV using Channel Domain Systems

The CDS (Channel Domain System) logically extends channel allocation capability over limited channel resources. The CDS provides CPs with flexible channel mapping mechanisms for various IPTV applications. Examples of such applications include channel naming using phone numbers and company names. The advantage of the CDS is two folds; it reduces cost of channel management and also, it facilitates usability of virtual channel for commercial and personal purposes. Proposed CDS mechanisms have been successfully implemented and applied in building commercial IPTV services.
