ABSTRACT:
An decoder apparatus for use in a TV receiver, for processing a MUSE bandwidth-compressed television signal, in which a field of that signal which occurs one frame interval prior to the currently received field is used as a reference field for motion vector compensation operation in which images in static regions of every four successive frames are combined, to obtain high display definition for such regions during overall motion of the television picture. As a result, the apparent central position of a moving region in the displayed picture (when that region is incorrectly processed as a static region) and the central position of that moving region (when it is correctly processed) are made closely adjacent, thereby substantially eliminating adverse effects in a display picture which can occur due to such erroneous processing.
