Abstract
In a device for spatio-temporal sub-sampling of digital video signals representing a succession of interlaced or sequential images divided into blocks of m.times.n points (m and n being positive integers), the device comprising, in series, a circuit for the spatial prefiltering of the said sequence of fields, which circuit is intended to deliver a succession of sequential images which are limited with respect to the bandwidth, a spatial sub-sampling circuit, and a temporal sub-sampling circuit: a motion estimator which on the basis of, on the one hand, signals corresponding to the even fields and on the other hand, signals corresponding to the odd fields, delivers one or more information items on the motion in an odd field with respect to the which surround it.
