Abstract
The invention comprises a method and apparatus for managing a multicast tree using SIP, SOAP, HTTP, or similar signaling between a multicast receiver (e.g., user device) and a third party system (e.g., a content provider system). The method includes receiving at least one request for modifying the multicast tree, determining at least one multicast tree change in response to the at least one request for modifying the multicast tree (where the at least one multicast tree change is operable for modifying the multicast tree according to the at least one request), and generating at least one message operable for implementing the at least one multicast tree change. The at least one request and the at least one message are implemented in a manner tending to minimize consumption of network resources.
