Abstract

A single-band remote control for controlling different categories of remote devices, and multiple remote devices of the same category, the remote control has a plurality of control keys divided into a plurality of frequency groups. The control keys of the same frequency group are operative to generate and transmit control signals with different identification data at the same frequency, while the control keys of different frequency group are operative to generate control signals with different frequencies within the same frequency band. Thereby, different types of remote devices and/or multiple remote devices of the same category can be controlled by the same remote control.

Claims

1. A remote control method using a remote control having a plurality of control keys on a control panel thereof to control a plurality of groups of remote devices, the method comprising:

pressing at least one control key to generate a control signal carrying an identification data at a specific frequency;

comparing the frequency of the control signal with operation frequencies of the groups of remote devices, so as to find a matching group;

comparing identification data of the remote devices of the matching group, so as to find a matching remote device; and

activating or inactivating the matching remote device.

2. The method of claim 1, further comprising dividing the control keys into a plurality of groups operative to generate control signals at different frequencies within a single frequency band.

3. The method of claim 1, further comprising configuring each of the control keys of the remote control responsible for controlling a respective one of the remote devices.

4. A method of remotely controlling a plurality of groups of remote devices, comprises:

providing at least one remote control having a plurality of control keys;

dividing the control keys into a plurality of frequency groups each being responsible to generate a control signal at a frequency operable for one respective group of the remote devices and an identification data matching with an identification data of one remote device of the respective group; and

pressing at least one of the control keys to control at least one of the remote devices.

5. The method of claim 4, wherein the remote control has a single frequency band and the operable frequencies of the remote devices are within the single frequency band.

6. A remote-control system, comprising:

at least one single-band remote control, which comprises;

a plurality of control keys divided into a plurality of frequency groups for generating control signals with different frequencies, wherein each frequency groups include a plurality of the control keys for generating control signals with different identification data; and

a plurality of remote devices each being controlled by respective one of the control keys.

7. The system of claim 6, wherein the control signals generated by different frequency groups have different frequencies within a single frequency band.

8. The system of claim 6, wherein the same category of remote devices is controlled by the same frequency group of control keys.
