Abstract

The motivations for the final system choices of a commercial improved quality PAL receiver are described. The receiver is based on fixed spatio-temporal filters for luminance-chrominance separation. The filters were designed according to hardware complexity and subjective performance evaluation, and according to three-dimensional spectral analysis tests which are nonstandard in television practice. Particular emphasis is placed on the demonstration of the practical feasibility of nontrivial spatio-temporal filters in commercial PAL decoders and on the use of nonconventional frequency domain analysis as an effective performance assessment tool for television systems
