Abstract: Method and means for evaluating the quality of audio and/or video transfer characteristics of a device upon which, or through which, audio and/or video information is contained, or passes, respectively. Both method and apparatus concern the evaluation of the quality of information transfer in the recording and playing back of a recording medium or in the transferring of audio and/or video information through an information handling device referred to as a throughput device. Unit evaluation is accomplished by establishing an input signal of known content, measuring selected parameters of selected parts of the input signal, feeding the input signal to the unit under test, measuring the parameters of parts of the output signal from the unit under test corresponding to the same selected parts of the input signal, and comparing the selected parameters of the input signal with the corresponding parameters of the output signal. Whether monitoring the quality of the signal transfer characteristics of a throughput device, a magnetic tape containing program material, or a video disc, master disc or replica, a "signature" is created for the unit under test, and subsequent analysis of the unit as it progresses along a production line or of a copy made on the same or alternate recording medium results in a second "signature" which is compared against the first signature to make a determination as to the quality of the signal handling or transfer characteristics of the unit. In this manner, out-of-tolerance conditions can be automatically detected, thereby eliminating subjectivity and providing consistency in the quality level of device testing.

Abstract: Die beschriebene Anordnung zur Erkennung von Pausen in einem Sprachsignal ermöglicht die Pausenerkennung auch dann, wenn dem Sprachsignal ein langsam veränderliches Störsignal überlagert ist. Zur Pausenerkennung werden aus den Abtastproben des gestörten Sprachsignales laufend an einen Takt gebundene sogenannte Kurzzeitmittelwerte bestimmt, die ein Maß für die mittlere Leistung von etwa 100 ms langen Abschnitten des gestörten Sprachsignales sind. Die Folge dieser Kurzzeitmittelwerte wird sodann durch lineare Filterung oder durch ein Medianfilter geglättet. Parallel zum Glättungsvorgang wird aus der Folge der Kurzzeitmittelwerte ein Schätzwert für die über einige Sekunden gemittelte Leistung des Störsignales gewonnen. Ist der geglättete Kurzzeitmittelwert einmal oder mehrmals kleiner als eine zum erwähnten Schätzwert proportionale Schwelle, so wird auf Sprachpause entschieden.
