IPTV ARCHITECTURE FOR DYNAMIC COMMERCIAL INSERTION

摘要

Dynamic delivery of different commercials to different viewers is achieved using a network node within an IPTV packet- switched network that is coupled to receive both a multicast television program and commercial programs. The network node is able to identify one or more subscribers to the multicast television program and to identify targeted commercial programs for each of the subscribers. The network node further includes a commercial inserter for inserting the respective targeted commercial program for each of the subscribers into the multicast television program to produce respective customized programs and to transmit the customized programs towards the respective subscribers.
