Abstract

The present invention relates to a universal remote control system comprising a remote control means and one or more receiver modules installed in the device to be controlled by the remote control means. The remote control means includes an input means and a signal emitter means. The receiver module includes a signal receiver means, a command code database and a processor means. The user commands input via the input means are in the form of simple English language understandable by average users comprising alphanumeric characters.

Claims

1. A universal remote control system comprising

(a) remote control means which includes

(i) input means for accepting human language user commands in text format comprising an address code component, a command code component and an end-of-command indicator which are input by users and generating the corresponding wirelessly transmittable signals comprising an address signal component and a command signal component;

and

(ii) signal emitter means for wirelessly transmitting the signals;

(b) one or more receiver modules installed in the device to be controlled by the remote control means, each of the receiver modules includes

(i) signal receiver means for storing one or more identification codes representing the device, detecting and receiving the signals emitted by the signal emitter means with the address signal component corresponding to one of the identification codes of the device;

(ii) command code database for storing a pre-defined set of the command signal components and the corresponding function to be performed for each of the command signal components, wherein one or more different command signal components may correspond to the same function to be performed;

(iii) processor means for receiving the command signal component of the signal received by the signal receiver means, searching the command code database for the corresponding function to be performed, and controlling the function to be performed.

2. A universal remote control system as in claim 1, wherein the address code component and the command code component of the user command are in the form of simple English language understandable by average users comprising alphanumeric characters and are preferably formed by one or two words;

the signals generated by the input means are digital signals which are transformed from the human language user commands to their corresponding ASCII codes in binary forms.

3. A universal remote control system as in claim 1, wherein the user command is in the form of <

address code component, separator, command code component>

, wherein the separator may take the form of “

,”

, “

/”

, “

;

”

or any other non-alphanumeric characters as pre-defined.

4. A universal remote control system as in claim 1, wherein the user command further comprises a security code component;

the security code component will be transformed into a security signal component of the signal by the input means and the security signal component is transmitted by the signal emitter means together with the address signal component and the command signal component;

the processor means of the receiver module is provided with a function for accepting or updating a device security code input via the remote control;

the processor means will not control the device to perform any functions if the security signal component received by the signal receiver means does not correspond to the device security code.

5. A universal remote control system as in claims 1 or 4, wherein the user command is in the form of <

address code component, separator, security code component, separator, command code component>

, wherein the separator may take the form of “

,”

, “

/”

, “

;

”

or any other non-alphanumeric characters as pre-defined.

6. A universal remote control system as in claim 1, wherein one or more function keys are provided on the input means and the activation of each function key represents the input of a predefined human language user command.

7. A universal remote control system as in claim 1, wherein the processor means is able to control the device to output an error signal if the command signal component received by the signal receiver means does not correspond to any of the command signal components in the command code database.

8. A universal remote control system as in claim 7, wherein the command signal component received by the signal receiver which does not correspond to any of the command signal components in the command code database is stored in the command code database and the corresponding function to be performed thereof is initially defined to be “

output an error signal”

.

9. A universal remote control system as in claim 1, wherein the command code database is editable and expandable so that users or manufacturers may add new command signal component in order to accommodate additional functions.

10. A universal remote control system as in claim 1, wherein the processor means of the receiver module is provided with a function for the user to update the identification code via the remote control so that users may choose an easy-to-remember name to identify the device.

11. A universal remote control system as in claim 1, wherein the input means is a keyboard or a digitalizing tablet provided in a hand-held case.

12. A universal remote control system as in claim 1, wherein the remote control means may be in the form of a mobile phone or personal digital assistant (PDA) provided with the hardware and software to transmit signals to the receiver modules.
