Abstract

A remote control transmission monitoring system. The system monitors remote control transmissions for the purpose of updating state tables for one or more remotely controllable appliances. The state tables may then be queried for the purpose of determining the present state of an appliance whereby the transmission of a command that would place an appliance in an unintended state may be avoided.
