Black-and-White Television Monitoring and Video Levels
Generation of video waveforms by live and telecine cameras is reviewed, together with the basics of picture and waveform monitoring devices. The degree of industry standardization in North America is reviewed. Monitoring procedures are discussed, and the need for accurate control of video peak-to-peak voltages is justified by considering them relative to transmitter and video-tape recorder modulation, film recording, network transmission and the retention of picture esthetics from source to audience. Accurate interpretation of the oscilloscope display is emphasized, black-and-white references are considered and the relation of these to face tones and glints is discussed. The effect of white clipper operation is considered. Some recommendations are offered.
