Abstract

Abstract of the Disclosure

A coupling device to connect an external device, e.g. a mobile station, to a television receiver through a SCART or antenna connection using an LPRF link (e.g. Bluetooth). The coupling device contains the necessary electronics to receive the signal sent from the mobile station as an LPRF radio signal and convert it to a format suitable for television. The coupling device can be built as a small adapter that attaches directly to the SCART connector of the TV. The coupling device can be arranged to be capable of e.g. relaying a signal from a video recorder to the TV and to replace the signal with a signal presenting the information sent by the mobile station.

Claims

1. A coupling device for attaching an external device to a television device, which television device has a first input to receive a certain external information signal in certain first format, wherein the coupling device comprises

short range radio communicating means for receiving information from the external device;

means for converting received information to an information signal in a first format; and

a first output for supplying said information signal in the first format to the first input of said television device.

2. A coupling device according to claim 1, wherein

the coupling device comprises a second input for receiving an external picture signal to be relayed to the television device through said first output.

3. A coupling device according to claim 1, wherein

said first output is a SCART-connector.

4. A coupling device according to claim 1, wherein

said first output is an antenna cable connector.

5. A coupling device according to claim 2, wherein

said coupling device comprises switching means to disconnect a signal entering said second input from said first output when the coupling device is communicating with said external device and to connect the signal entering the second input to said first output when the coupling device is not communicating with said external device.

6. A coupling device according to claim 1, wherein

said external device is battery operated, and

said coupling device comprises means for charging a battery of said external device.

7. A coupling device according to claim 1, wherein the coupling device comprises

means for receiving a second information from a television program source;

and

means to send said second information through a short range radio connection to said external device.

8. A coupling device according to claim 1, wherein

said information comprises at least one of the following:

picture and sound information.

9. A coupling device according to claim 1, wherein

said external device is a mobile station.

10. A coupling device according to claim 1, wherein

said short range radio connection is an LPRF link.

11. A coupling device according to claim 1, wherein

by coupling said first output to said first input said external device is detachably attachable to a television device.

12. A coupling device according to claim 1, wherein said external device comprises means for attaching said external device detachably to a television device.

13. A system comprising an external device and a television device,

which external device has short range radio communicating means for receiving certain external information signal in a first format, wherein

the system comprises a coupling device for receiving information from an external device to a television device to be presented on the television device, which coupling device comprises:

short range radio communicating means for receiving information from an external device;

means for converting the received information to an information signal in said first format; and

a first output to supply said information signal in the first format to the first input of said television device.

14. A method for coupling an external device to a television device, which television device contains a first input to receive an external information signal, wherein

a coupling device is attached to the first input to receive information;

information sent on a short range radio connection is received from an external device;

received information is converted to a first format suitable to the television device; and

information in said first format is supplied to said first input.
