ABSTRACT:
A video signal processor includes a motion vector estimation system having a first operating mode for performing frame-structure processing and a second operating mode for field-structure processing. The system includes N motion estimator units, each of the units receiving two respective time separated data blocks, wherein N units are operating during the first operating mode, wherein M of the N units are operating during the second operating mode and wherein (N-M) units provide motion estimating processing outside of an area of an image represented by the data blocks. According to one aspect of the present invention, N is an integer greater than 2 while M is an integer less than N.
