Abstract

Abstract Translated from German Bei einer Einrichtung zur bandbreitenreduzierenden Codierung von Videosignalen werden die Videosignale bezüglich ihrer Frequenz in mehrere Teilbänder aufgespalten. Auf die in den Teilbändern jeweils vorliegenden Signale werden verschiedene Datenreduktionsverfahren angewendet. Die Aufspaltung erfolgt in ein erstes Teilband (Tiefpaß-Teilband) und mindestens ein weiteres Teilband (Hochpaß-Teilband). <IMAGE> In the case of a device for bandwidth-reducing coding of video signals, the frequency of the video signals is split into several subbands. Various data reduction methods are applied to the signals present in the subbands. The splitting takes place into a first sub-band (low-pass sub-band) and at least one further sub-band (high-pass sub-band). <IMAGE>
