Abstract

Disclosed is a method for communicating audiovisual signals over a communication network interconnecting a plurality of devices, wherein the method comprising the steps of: selecting an audiovisual signal at a first device; transmitting an indication message from the first device to a group of devices over the communication network, said indication message containing a set of parameters associated to the selected audiovisual signal; selecting a second device among the group of devices, said selection being performed at said second device; and establishing a connection for retrieving at the selected second device the audiovisual signal using at least one of the set of parameters.

Claims

1. A method for communicating audiovisual signals over a communication network interconnecting a plurality of devices, wherein the method comprising the steps of:

selecting an audiovisual signal at a first device;

transmitting an indication message from the first device to a group of devices over the communication network, said indication message containing a set of parameters associated to the selected audiovisual signal;

selecting a second device among the group of devices, said selection being performed at said second device; and

establishing a connection for retrieving at the selected second device the audiovisual signal using at least one of the set of parameters.

2. A method for communicating audiovisual signals over a communication network interconnecting a plurality of devices, wherein the method comprising the steps of:

selecting an audiovisual signal at a first device;

transmitting an indication message from the first device to a predetermined second device over the communication network, said indication message containing a set of parameters associated to the selected audiovisual signal; and

selecting a third device among the plurality of devices, said selection being performed at said third device;

transmitting a request message for getting from the predetermined second device it least one of the set of parameters associated to the selected audiovisual signal;

end

establishing a connection for retrieving at the selected third device the audiovisual ;

ignal using the at least one of the set of parameters.

3. A device for communicating audiovisual signals over a communication network interconnecting a plurality of devices, comprising:

means for inputting first selection data causing the selecting of an audiovisual signal;

means for transmitting an indication message to a group of devices over the communication network, said indication message containing a set of parameters associated to the selected audiovisual signal;

means for receiving a set-up message regarding the selected audiovisual signal from at least one device of the group of devices; and

means for causing to establish a connection for the at least one device in response to the received set-up message to retrieving the selected audiovisual signal.

4. A device for communicating audiovisual signals over a communication network interconnecting a plurality of devices, comprising:

means for receiving one or more indication messages, each indication message containing a set of parameters associated to an audiovisual signal;

means for inputting first selection data causing the selecting of a destination device;

means for determining one audiovisual signal from a list of audiovisual signals, the list being formed based on the received indication messages; and

means for establishing a connection for retrieving at said destination device the audiovisual signal in response to the determination means using at least one of the set of parameters.

5. Device according to claim 4, wherein the set of parameters comprises the identifier of an original destination device and said device comprises further a means for outputting indicative data for indicating if the identifiers of the original destination device and the selected destination device are equal or not.

6. Device according to claim 4, wherein the determining means comprises:

means for inputting second selection data; and

means for selecting the one audiovisual signal among the list of audiovisual signals using said second selection data.

7. Device according to claim 4, wherein it further comprises a transmitting means and wherein the receiving of one or more indication messages by the receiving means is performed in response to the transmitting of a request message by the transmitting means.

8. A computer program product, comprising program code instructions for the execution of the steps of a method for communicating audiovisual signals over a communication network interconnecting a plurality of devices, said program code instructions executed on a computer, the computer program product comprising:

first instructions for receiving one or more indication messages, each indication nessage containing a set of parameters associated to an audiovisual signal;

second instructions for inputting first selection data causing the selecting of a destination device;

third instructions for determining one audiovisual signal from a list of audiovisual signals, the list being formed based on the received indication messages; and

fourth instructions for establishing a connection for retrieving at said destination device the audiovisual signal in response to the determination means using at least one of the set of parameters.
