Abstract
Abstract A digital remote control device for use in a transmitter capable of transmitting an end code following each transmission code, which includes a counting circuit for counting the number of transmission operations performed by pressing a key or keys on the transmitter; and an end pulse changing circuit for changing a configuration of the end code such that the configuration corresponds to a count value counted by the counting circuit.
