Abstract

A method is disclosed for remote control wherein coded commands are transmitted from a transmitter to a receiver. A respective time interval between a first energy impulse starting the transmission and a second energy impulse concluding the transmission is utilized as the coding which characterizes the individual command. Time intervals rigidly allotted to the individual commands are selected differently such that the differences formed by subtracting the time intervals have at least partially different values in relation to one another. The remote control is particularly useful for remote control hobby equipment.
