Abstract
A digital remote control method in which interference among different devices is eliminated by the use of a custom code and an instruction code. In accordance with the invention, a transmission code is generated composed of an instruction code and a custom code, with the custom code and instruction code differing in the number of bits contained in each. The custom code is transmitted prior to the instruction code with an interval therebetween longer than the intervals between adjacent pulses, which intervals define data '0' and '1'.
