ABSTRACT:
This invention is an apparatus and method for digital processing of television like signals and in particular the use of oversampling and interpolation to achieve improved resolution of the digital version of such signals as compared to a digital version obtained by the use of simple A/D conversion or processing at the desired sample rate. The preferred embodiment utilizes oversampling, interpolation and various filtering in recursive and nonrecursive form to provide output video signals wherein the artifacts and distortion of the video are kept to low levels.
