Abstract

A solution for transferring audiovisual data between devices is provided. A device, for example a guest device, wishes to transfer audiovisual data to a device in a host local network. The guest device connects to a server in a wide area network via the host local network. The guest device selects, via its connection to the server and from a list, provided by the server, of devices in the host local network, a device present in the host local network. The guest device retrieves via the list connection parameters for transferring audiovisual data to the selected device. The guest device connects to the selected device in the host local network using the retrieved connection parameters and transfers audiovisual data to the selected device.

First claim

1 . A method of transferring audiovisual data between devices in a local network, the method being implemented by a device in said local network:
accessing, by said device in said local network, to a list, provided by a server in a wide area network, of devices in said local network; retrieving, by said device in said local network and via said list, connection parameters for connecting, via said local network, said device in said local network to another device in said local network, selected from said list by said device in said local network; connecting, by said device in said local network, said device in said local network to said another device in said local network, using said retrieved connection parameters; transferring, by said device in said local network and via said connection to said another device in said local network, audiovisual data between said device in said local network and said another device in said local network.

2 . The method of transferring audiovisual data between devices according to claim 1 , further comprising receiving, by said device in said local network, an Internet Protocol address for use in said local network and transmitting, to said server, said Internet Protocol address, for determining by said server devices in said local network based on said Internet Protocol address.

3 . The method of transferring audiovisual data between devices according to claim 2 , wherein said Internet Protocol address transmitted to said server is said Internet Protocol address for use in said local network as translated by a Network Address Translator in between said local network and said server.

4 . The method of transferring audiovisual data between devices according to claim 1 , further comprising transmitting, to said server, an identification number of a gateway in said local network for determining by said server devices in said local network based on said identification number of said gateway.

5 . The method of transferring audiovisual data between devices according to claim 1 , further comprising transmitting, to said server, an identification number of said local network for determining by said server devices in said local network based on said identification number of said local network.

6 . The method of transferring audiovisual data between devices according to claim 1 , wherein said connection parameters comprise authorization data enabling access by said device to data storage in said another device in said local network for receiving audiovisual data from said device in said local network.

7 . The method according to claim 1 , wherein said server is a Service Provider server, and said list of devices in said local network provided by said server corresponds to subscriber devices of said Service Provider and in said local network.

8 . A device for transferring audiovisual data between devices in a local network, comprising a processor, a network interface and a memory configured to:
access, to a list, provided by a server in a wide area network, of devices in said local network; retrieve, from said server and via said list, connection parameters for connecting, via said local network, said device in said local network to another subscriber device in said local network, selected from said list; connect to said another device in said local network, using said retrieved connection parameters; and transfer via said connection to said another device in said local network, audiovisual data between said device and said another device in said local network.

9 . The device for transferring audiovisual data between devices in a local network according to claim 8 , wherein said processor, said network interface and said memory are further configured to receive an Internet Protocol address for use in said local network and to transmit to said server, said Internet Protocol address, for determining by said server devices in said local network based on said Internet Protocol address.

10 . The device for transferring audiovisual data between devices in a local network according to claim 8 , wherein said processor, said network interface and said memory are further configured to transmit, to said server, an identification number of a gateway in said local network for determining by said server devices in said local network based on said identification number of said gateway.

11 . The device for transferring audiovisual data between devices in a local network according to claim 8 , wherein said processor, said network interface and said memory are further configured to transmit, to said server, an identification number of said local network for determining by said server devices in said local network based on said identification number of said local network.

12 . The device according to claim 8 , wherein said server is a Service Provider server, and said list of devices in said local network provided by said server corresponds to subscriber devices of said Service Provider and in said local network.
