A method of remotely controlling communication of media between a first device in a first local network and a second device in a second local network, which is remote from the first local network, by a remote control device also present in the first local network, the first local network comprising a first residential gateway for external connections and the second local network comprising a second residential gateway for external connections, the method comprising:

  • obtaining, by the remote control device, discovery information on the first device by the remote control device conducting a discovery process in the first local network;

    the remote control device sending a remote access request over a multimedia service network to a home multimedia gateway in the second local network for a connection to the second device;

    the remote control device receiving communication parameters transmitted by the home multimedia gateway over the multimedia service network in response to said remote access request, said communication parameters comprising an external network address allocated to the second residential gateway; and

    the remote control device present in the first local network ordering the first device, which is also present in the first local network, to fetch an identified media content item from the second device present in the second local network, which is remote from the first local network, wherein ordering the first device present in the first local network to fetch the identified media content item from the second device present in the second local network comprises;

    the remote control device providing to the first device said received communication parameters allocated to the second residential gateway; and

    the remote control device providing to the first device a media content identifier identifying the media content item,wherein the remote control device present in the first local network is separate and distinct from the first residential gateway;

    wherein the step of providing the media content identifier to the first device consists of providing to the first device a Uniform Resource Locator (URL) or Uniform Resource Identifier (URI) comprising information pointing to the media content item;

    wherein the URL or URI further comprises the external network address allocated to the second residential gateway; and
