Abstract
A network device executes a method to provide targeted messages to a subscriber of Internet Protocol Television (IPTV) when a request of the subscriber to access an IPTV channel is denied. The method includes receiving the request of the subscriber from a customer premise equipment (CPE) to access a first multicast stream, where the first multicast stream is a multicast stream for an IPTV channel. The method further includes checking whether the request to access the first multicast stream should be allowed or denied, determining a reason for denial in response to determining that the request should be denied, determining a second multicast stream that corresponds to the reason for denial, sending a join message to a multicast source to receive the second multicast stream, and forwarding the second multicast stream to the CPE.
