摘要： Method and apparatus 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. Wheather 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.

摘要： A series of separate analog electrical signals are received at a real time rate and converted to digital equivalents. The converted signals are stored in a digital memory from which the signals are released serially at a rate slower than the real time rate at which the signals are received. The signals released from storage are directed to a signal analyzer, preferably after being converted from digital to analog format, for processing to determine prescribed parameters of the original analog electrical signals.

摘要： Method 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. The method concerns the evaluation of the quality of information transfer in the recording and playback 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 includes 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 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 of the quality of the signal handling or transfer characteristics of the unit. Thus out-of-tolerance conditions are automatically detected, thereby eliminating subjectivity and providing consistency in the quality level of device testing.

摘要： Method and apparatus for evaluating the audio characteristics of an audio-video program recorded on a storage member in which the video portion of the program contains picture frame code numbers. A predetermined picture frame number at which video evaluation of the audio portion of the program is to commence is initially established. The audio and video portions of the recorded audio-video program are recovered, and the picture frame code numbers are extracted from the video portion thereof. The extracted picture frame numbers from the recovered video portion are then compared with the predetermined picture frame number, and audio evaluation of the audio portion of the program commences upon coincidence of the detected picture frame number and the predetermined picture number. Evaluation is effected by measuring predetermined audio characteristics of the recovered audio portion and comparing the measured characteristics with corresponding audio reference characteristics. In a preferred embodiment, the measured audio characteristics of a first storage member are stored in a memory device and used as a "signature" for comparision with measured audio characteristics of a second storage member.

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.
