    The Grade A and Grade B service contours of a television broadcast station are used for a host of administrative purposes by the FCC including the regulation of CATV systems. Additionally, the contours are used by most stations for promotional and marketing purposes. The numerical values associated with these contours represent levels of field strength; consequently, assumptions were made in their determination as to noise limitation, the antenna gain, and transmission-line loss of the receiving system. Also, consideration was given to the subjective nature of picture quality and the statistical variation of field strength with time and location. The nature of these variables is discussed and the assumed values are tabulated in a format suitable for easy understanding and for analysis of possible future changes. View full abstract»

    A loudness limiter which reduces disparity in loudness levels, when a program is controlled on a vu basis, has been developed by CBS Laboratories. The device evaluates the loudness level of the program by a "loudness level summation" method described previously by the authors, and automatically reduces the program level when a preset threshold is exceeded.
