Abstract : The techniques for testing digital television systems which incorporate signal processing for the purpose of reducing the number of bits which need to be transmitted to define a video frame are, at this time, poorly defined. In general, purely subjective test procedures have been used to date. It would be desireable to produce a set of quantitative data which correlates directly with a set of qualitative data. The qualitative data will serve as the initial criteria for the evaluation of codec performance. Analysis of the correlation between the quantitative and qualitative data will then permit the development of a set of quantitative tests whose results will serve as a non-subjective standard for the future evaluation of codecs.
