Abstract:
1. A method for delivering targeted advertising to Internet Protocol television (IPTV) clients, the method comprising: receiving by a server device from a client of the IPTV clients a start over request for a current multicast stream; determining that a storage time associated with the requested current multicast stream is not expired; retrieving by the server device from a storage device at least one cached copy of the requested current multicast stream; inserting by the server device at least one advertisement targeting the client in the retrieved at least one cached copy of the requested current multicast stream by replacing a default advertisement; increasing said storage time of the requested current multicast stream to enable using longer advertisement without prematurely terminating said requested current multicast stream, if the at least one advertisement is longer than the default advertisement; and transmitting, by the server device, the retrieved at least one cached copy of the requested current multicast stream including the at least one advertisement toward the client.
