Abstract
A remote control system utilizes a portion of television receiver system to control an external appliance through the AC power supply line. The user enters an appliance control command into the keyboard of the television remote control unit. Inside the television receiver, the appliance control command is encoded and modulated onto a carrier signal which is transmitted on the AC power supply line. An external appliance control module, also connected to the AC power supply line, is located near the external appliance for detecting the encoded appliance control command and for selectively controlling the AC power supplied to the external appliance.
