Abstract
An rf PC interface transmits binary coded radio-frequency (rf) signals which are binary coded in accordance with software resident in a PC. The interface is plugged into a serial port of the PC and includes a pass-through port and an rf modulator. Also disclosed is an rf transceiver which receives and demodulates addressed coded rf signals, which are then combined with the appropriate audiovisual product remote control signals to drive an IR transmitter to produce remote control signals for the addressed audiovisual product.
