Revision Standard - Inactive-Withdrawn.
A method of measuring the amplitude levels of an SMPTE 170M-1994; NTSC color or monochrome television video signal is described. It is concerned with luminance measurements at various points in transmission systems where the signals are at video frequencies. The methods described are limited to the use of waveform monitors, software video processing for amplitude assessment, or suitable oscilloscopes, and are primarily directed to specifying means of measuring television signal levels for operating purposes.
This standard describes a method of measuring the amplitude levels of an SMPTE 170M-1994,1 NTSC color or monochrome television video signal. It is concerned with luminance measurements at various points in transmission systems where the signals are at video frequencies. The methods described in this standard are limited to the use of waveform monitors, software video processing for amplitude assessment, or suitable oscilloscopes, and are primarily directed to specifying means of measuring television signal levels for operating purposes.
This standard provides a uniform method to measure the luminance portion of a video signal in the
possible presence of large chrominance portions. It also specifies a method of measuring video levels in a manner permitting ready correlation between measurements at different points of a system,
regardless of the nominal voltages present.
