Abstract

A method and apparatus enabling the usage of a remote display monitor for presenting display data from a mobile telephone is disclosed. A mobile telephone includes a display monitor communication function enabling the generation of a communications link between the mobile telephone and a receiver of a display monitor. The communications link enables the transmission of numeric and textual data intended to be displayed on a display associated with a mobile telephone on the larger screen of the remote display monitor. The type of data presented on the display monitor may be selectively programmed by a user.

Claims

1. A system for displaying on a remote display monitor display signals from a mobile telephone, comprising:

a receiver connected with the remote display monitor for receiving the display signals to be displayed by the remote display monitor; and

a transmitter associated with the remote display monitor for transmitting data to the mobile telephone;

a monitor communications function connected with the mobile telephone for generating a communications link with the receiver to enable the display signals from the mobile telephone to be transmitted to and displayed by the display monitor, said monitor communications function further responsive to transmitted data from the display monitor.

2. The system of claim 1 wherein the monitor communications function includes means for automatically actuating the communications link in response to detection of the receiver.

3. The system of claim 1 wherein the monitor communications function further includes means responsive to a user input for actuating the communications link with the receiver.

4. The system of claim 1 wherein the communications link comprises an IR communications link.

5. The system of claim 1 wherein the communications link comprises an RF communications link.

6. The system of claim 1 wherein the remote display monitor comprises a television.

7. The system of claim 1 wherein the remote display monitor comprises a computer display.

8. The system of claim 1 further including command menu means for providing a display to the user of a plurality commands associated with the display monitor and for enabling selective programming of, in response to user inputs, the display of data transmitted to the remote display monitor from the mobile telephone.

9. A system for displaying on a remote display monitor display data from a mobile telephone, comprising:

a receiver connected with the remote display monitor for receiving the display signals to be displayed by the remote display monitor;

a monitor communications associated with the mobile telephone for generating a communications link with the receiver to enable the display signals from the mobile telephone to be transmitted to and displayed by the remote display monitor; and

command menu means for providing a display to the user of a plurality commands associated with the remote display monitor and for enabling selective programming of, in response to user inputs, the display of data transmitted to the remote display monitor from the mobile telephone.

10. The system of claim 9 wherein the communications link comprises an IR communications link.

11. The system of claim 9 wherein the communications link comprises an RF communications link.

12. The system of claim 9 wherein the remote display monitor comprises a television.

13. The system of claim 9 wherein the remote display monitor comprises a computer display.

14. The system of claim 9 further including a transmitter for transmitting signals from the remote display monitor to the mobile telephone.

15. A method for displaying data from a mobile telephone on a remote display monitor, comprising the steps of:

receiving display data for display on the display of a mobile telephone at the mobile telephone;

forming a communications link between the mobile telephone and the remote display monitor;

transmitting the display data from the mobile telephone to the remote display monitor through the communications link;

entering at the mobile telephone a command for controlling display of the display data on the remote display monitor;

confirming receipt of the command from the remote display monitor to the mobile telephone; and

displaying the display data from the mobile telephone on the remote display monitor according to the command.

16. The method of claim 15 wherein the step of forming further includes the step of generating the communications link in response to a user generated input from the mobile telephone.

17. The method of claim 15 wherein the step of forming further includes the steps of:

scanning by the mobile telephone for a presence of a receiver associated with the display monitor;

forming the communications link upon detection of a presence of the receiver.

18. The method of claim 15 wherein the step of forming further comprises the step of forming an RF communications link.

19. The method of claim 15 wherein the step of forming further comprises the step of forming an IR communications link.

20. The method of claim 16 further including the step of transmitting a confirmation of formation of the communications link from the display monitor to the mobile telephone.
