ABSTRACT:
This MPEG Decoder relates to the decoding of an image that can be of a bi-directional type requiring data from two previously decoded images, each image being displayed in two successive fields corresponding to lines with different parities. Each bi-directional image is decoded twice during its display time, a first time as a first field of the image is being directly displayed, and a second time as the second field is being directly displayed.
