Description
Early infrared (IR) remote control systems employed a simple on-off modulation of an IR LED to transmit the control data between the remote control and the appliance. Unfortunately, while this method was simple to implement, it suffered from both interference and range problems. A warm object, or a reflection of the sun in a window could, and often did, mask the IR energy received from the transmitter, reducing it?s effective range. In addition, mechanical modulation of an IR source (for example, air moving a window shade) often resulted in the reception of garbled or erroneous commands by the receiver.
