Abstract
For the transmission of signals triggered by long key depressions from a transmitter to a receiver, repeat signals (R) are transmitted while the key is held down. Releasing the key triggers a separate shift signal (S). A burst-pause modulation method is used to transmit the repeat and shift signals (R) and (S). Information units are defined here by different lengths of the burst intervals. The burst intervals and the burst packets are selected in such a way that infrared transmitters with a limited power supply can be used.
