Claim One:
1. For use in a receiver, a video enhancement mechanism for enhancing video information with spatio-temporal consistency comprising: at least one enhancement unit enhancing a characteristic other than position of a selected pixel region of video information utilizing at least one candidate enhancement vector of enhancement algorithms to generate an enhanced pixel region for each candidate enhancement vector, each said enhanced pixel region equivalent to enhancement of said selected pixel region utilizing a respective candidate enhancement vector of enhancement algorithms; and a selection unit computing an error for each said enhanced pixel region utilizing a bias towards spatio-temporal consistency of a respective enhanced pixel region with spatially adjacent pixel regions in a picture containing said selected pixel region and with a counterpart pixel region in one or more pictures successive with said picture containing said selected pixel region, said selection unit selecting an enhanced pixel region having a best enhancement for spatio-temporal consistency.
