Some Methods of Automatic Analysis of Television Test Signals
Investigations have been made into methods of digitally analyzing television test signals to be used in a prototype automatic monitoring equipment. To allow, wherever possible, maximum compatibility with existing manual methods, the already established insertion test signals (ITS) were employed. A preliminary survey confirmed that the component waveforms of ITS were generally amenable to digital analysis, although in some cases the approach would have to be quite different from that adopted for manual assessment. The effects of noise had to be taken into account. Suitable methods were found to be available for analyzing insertion test signals by means of an on-line digital computer to obtain the relevant transmission quality parameters.
