Fremgangsmåte for reduksjon av data ved overföring og/eller lagring av digitale signaler fra flere innbyrdes avhengige kanaler

摘要

described is a method for reducing data in the transmission and / or storage of digital stereo signals. $a as the signals from two stereo channels are not independent from each other, the transmission of a further reduction of the amount of data possible.$a known procedure for coding of stereo in unfavourable signalzusammensetzung disturbances by coding the actual channel existing signal not be masked and the hu00f6rgenuu00df cloudy.$a in the erfindungsgemu00e4u00dfen procedure using the spektralwerte korrespondierender blocks of the two channels or the required data rate for a separate coding of the two channels and a common coding is carried out.a joint coding of the two channels is, as long as the data rate for the common coding the data rate for the separate coding of the two channels is not a specific value exceeds. in this case, the spektralwerte resemble the corresponding blocks, so that a joint coding is preferred.$a very unlike signals, the accounting to a separate transmission of the signals. for the safe avoidance of disturbance will be temporarily on the use of stereocodierung renounced.
