Abstract:
1. A method for delivering targeted advertising to an Internet Protocol television (IPTV) client, comprising: monitoring a multicast stream adapted to be received by the client to detect therein a splice-in point associated with a default advertisement, wherein an access node is adapted to terminate delivery of the multicast stream to the client at a time contemporaneous with a splice-in time; providing, in response to said detection, a replacement advertisement within a unicast stream adapted to be received by the client; transmitting toward the client a command adapted to cause a channel change mechanism within the client to select the unicast stream for processing at a time contemporaneous with the detected splice-in point; and replicating by the access node the multicast stream for each of a plurality of clients, the steps of terminating and restarting delivery of the multicast stream comprising, respectively, terminating and restrating replication of the multicast stream by the access node.
