Abstract: An experimental system for monitoring and measuring test signals inserted in TV lines 19 and 20 of the British 625-line PAL color TV signal has been undergoing evaluation by the Independent Broadcasting Authority. Measurements are made automatically, using a fast analog/digital converter and digital computer, of signals received over the air from various UHF relay stations in the Midlands region of the U.K., and alarms may be given if any of 15 parameters exceeds a preset limit. The parameters consist of five luminance parameters (2T-pulse “width” and “lobes,” “bar-tilt” and 2T pulse-to-bar ratio, and luminance (staircase) nonlinearity); five sync signal parameters (color-burst amplitude, duration and position and line sync pulse width and amplitude); and five chrominance parameters (differential gain, differential phase, chrominance-to-luminance gain and delay ratios and chrominance-to-luminance crosstalk). Examination of cost considerations revealed that the centralized monitoring method is more economical than an alternative method if more than three stations must be monitored.
