Abstract:
A versatile video transformation device that allows for conventional television sets to utilize input signals with HDTV, DTV or formats with enhanced data communications, compression, and improved picture quality perception comprising:means for decoding said signal and scan converting them into an enhanced visual image from standard TV raster format and which comprises;means for spatial and temporal filtering said input signals by adaptive sampling said input signals into selectable adjacent arrays, determining a selected value for each array, said selected value being selected from one of the median, mean (average) of the input signals and a sample value of each array about a center pixel defined with respect to the raster origin which is offset from a previous raster origin in the respective arrays, and displaying at least one single pixel in the array dependent on said selected value; andwherein field sequential arrays are filtered and said selected value for each array that is used to readout a video value in each array is determined based upon the decoded picture content, image motion, and respective origins that are offset with respect to each other in an ordered dither fashion for error diffusion.
