Abstract

A method and apparatus are provided for motion compensated coding of interlaced digital video signals. A first prediction error signal is obtained (74) indicative of the difference between a current portion from a field of a current video frame and a similarly situated first portion in the same field of a prior video frame. A second prediction error signal is obtained (76) indicative of the difference between the current portion and a similarly situated second portion in an opposite field of the prior video frame. A third prediction error signal is obtained (78) indicative of the difference between the current portion and an average of the first and second portions. One of the first, second and third prediction error signals is selected (80) to represent the current portion. Motion vector information is provided (72) to enable the current frame portion to which the selected prediction error signal corresponds to be reproduced by a decoder (Fig. 10). <IMAGE>
