Patent DE-19851082-A1 (DE)
Title: Digital remote control signal transmission
Inventor: DELAPORTE FRANCIS
IPC: G07C9/00
Filed: 1998-11-05
Abstract: To limit the task of the reception, a transmission step frequency is limited in a buffer circuit (1) of a receiver by dividing the signals to transmission blocks of a predetermined size. The transmission blocks are transmitted to the buffer circuit with a higher transmission rate than the transmission step frequency, so that the entire calculation power freed up by the limited reception task can be utilized for the signal processing. The method involves transmitting digital remote control signals from a transmitter to a receiver (1, 2) which contains a buffer circuit (1) at its input for the reception of the digital remote control signals and for their transmission to a processor (2), having a predetermined divided computational power for the reception of the transferred signals and their processing.  To limit the task of the reception, the transmission step frequency is limited in the buffer circuit by dividing the signals to transmission blocks of a predetermined size. Before sending out the signals, the transmitter codes their logical condition in form of a pulse which has a specific position in a period (T) of predetermined duration. The transmission blocks are transmitted to the buffer circuit with a higher transmission rate than the transmission step frequency, so that the entire calculation power freed up by the limited reception task can be utilized for the signal processing.
