1. A method of controlling delivery of media data to a plurality of target devices in a target network, the method comprising, in a communications control system:
storing target device group control data for controlling the transmission of media data to at least a first plurality of target devices in the target network, the target network being connected to the communications control system via an access network, the communications control system being located outside the target network; receiving a media data delivery initiation request from a source device located in the target network, the request comprising a target device group indicator; retrieving target device group control data, from the stored target device group control data, based on the target device group indicator contained in the media data delivery initiation request; and transmitting a media data delivery initiation response to the source device, the response comprising the retrieved target device group control data, the retrieved target device group control data identifying at least one network address in the target network to which media data is to be transmitted by the source device, whereby to deliver media data to the first plurality of target devices, wherein the at least one network address comprises an address for which, when media data is transmitted to the at least one network address by the source device, media data is delivered to the first plurality of target devices via the target network and not via the access network. |
