Method and device for branching and inserting digital signals.

摘要

The signal extraction and insertion method is applied to digital signals (DSA1...DSB1) transmitted via multiplex signal channels. The incoming multiplex signals (MSE1, MSE2) are transformed into multiplex signals (MDE1, MDE2) in which each data word has double the original bit rate and gaps of even length, an odd or even bus time slot being assigned to the transformed multiplex signals to obtain a common time multiplex reception signal fed to all peripherals (KK1...KKn) at which the digital signals are obtained. The transmitted digital signals from the peripherals are combined to a common multiplex signal (ZMS) and a digital signal (EDSA1) is inserted in the assigned channel (KB1) of a converted multiplexed signal (MDA1), which is then standardised.
