ALSO NUMBERED AS BS EN 61041 PT1 Describes methods of measurement performance of non broadcast video tape recorders of the so called 'colour under' type for domestic use. Defines test signals, measurement set ups and measurement conditions. Covers normative references, environment, magnetic tape, interchangeability test, video test signal, AGC operation, luminance amplitude/frequency response, non linear distortion, waveform distortion, transient tearing, signal to noise ratio and drop out compensation; chrominance amplitude/frequency response, signal to noise ratio, luminance intermodulation, chrominance crosstalk, luminance displacement and luminance crosstalk.
