Picture Enhancement for PAL-coded TV Signals by Digital Processing in TV Receivers
Digital PAL-respective NTSC-decoding and sophisticated analog hardware have contributed to the sharp increase in digital processing of video signals for HDTV. This paper details several important steps in digital signal processing, discussing signal separation with digital filters, improvement of picture sharpness, aperture correction of luminance channels, switching equalization of chrominance channels, and noise reduction. The processing of luminance and chrominance channels is outlined, with supporting figures and illustrations throughout.
