An infra-red remote control system designed for universal control

Remote control is already part of the everyday life. However, there is no truly universal remote control which can control all appliances at home. This paper proposes an infra-red remote control system which can make it a possibility. The system is based on an innovative link procedure and is demonstrated in a system controlling main switches. The hardware and software details are described. An ASIC chip for the receiver is designed to simplify the integration with main switches.
