Abstract
An electronic appliance equipped with an infra-red or ultrasonic remote control device in which the device is controlled from a great distance by receiving control signals transmitted from a remote station (6), reformatting the control signals (3) in the device to controm with the protocol required by the appliance to be controlled, and transmitting the infra-red (5) or ultrasonic signal to the appliance.
Claims24
A method of controlling a device, comprising:
- transmitting an information signal from a first transmitter;
- transmitting a control signal from a second transmitter, said control signal being indicative of a predetermined target condition, said second transmitter disposed apart from a receiving device;
- receiving said information signal at a receiving station;
- applying said received information signal to said receiving device at said receiving station;
- receiving said control signal at an intermediate station;
- sensing an operational condition of said receiving device, when said receiving device is in a power-on condition;
- formatting said received control signal according to said sensed operational condition to form control codes suitable for reception by an input of said receiving device;
- using a third transmitter to modulate a carrier on the basis of said control codes;
- and
- applying the modulated carrier from said third transmitter to an input of said receiving device to cause said receiving device to enter said predetermined target operational condition, wherein the sensing of the operational condition of said receiving device further comprises:
- receiving a sequence of signals from a controller;
- and
- calculating a current operational condition of the receiving device according to said sequence of received signals.
