Black Level—The Lost Ingredient in Television-Picture Fidelity

R. G. Neuhauser

This paper outlines TV-system improvements instituted in recent years which produce and maintain the ability to reproduce proper black level (or d-c restoration) in the television receiver. The necessity for proper black-level control in the production of TV pictures having good fidelity is discussed, and factors which caused its importance to be minimized in the past are noted. Specific equipment and instrumentation advances which have resulted partly from the advent of color television are also described. The entire TV system, from the studio to the receiver, is considered. A suggested waveform standard that can be used to achieve day-to-day and station-to-station uniformity of black-level reproduction is illustrated.
