ABSTRACT:
The disclosure relates to a method of reception of signals from at least two transmitters (RCi), wherein for each transmitter the data ("0", "1") are represented by the time interval (T0i, T1i) between two consecutive pulses transmitted by this transmitter, said time intervals and the pulse widths (Tpi) being characteristic of each transmitter, and wherein said method includes the following steps: reception of a resultant signal that is the sum of the signals from by said transmitters; determination of the parameters of said resultant signal, these parameters including the width and spacing of the pulses; analysis of said parameters and assignment of a data item to one of said transmitters. The invention also concerns a receiver device, a remote controller, and a system of reception. The invention is applicable notably in the field of television and video.
