Method and multicast replication point for providing programs of a multicast group

摘要

The method involves transmitting a multimedia data stream through an Internet protocolbased distribution network to a multi-cast replication point (70). The data stream represents a program. A receiving device is connected by a subscriber access network. A determined sub-group-data stream is transmitted for receiving device, which requests a program. An independent claim is also included for a multi-cast replication point for inserting in an internet protocol television-communication system.
