Claim One:
1. A device for reproducing digitally received video pictures comprising an array of picture elements, said device including a restoration circuit for restoring erroneous picture elements located within a reference sub-picture within which said erroneous picture elements are enclosed by non-erroneous picture elements, said restoration process comprising: a preset process; and an iteration prediction process; characterized in that the preset process comprises: a substitution step for replacing the erroneous picture elements by predetermined fixed picture elements; a coefficient prediction step for determining a plurality of sets of prediction coefficients, each set being associated with the picture elements of a prediction field of a plurality of different prediction fields; a selection step for selecting said prediction field for performing the coefficient prediction step in the iteration prediction process and the associated set of prediction coefficients for which the prediction coefficient function has the smallest value; a picture element prediction step for determining the auxiliary picture elements on the basis of the prediction coefficients selected in the selection step; and a substitution step for replacing the original erroneous picture elements of the reference sub-picture by the auxiliary picture elements to compose the up-dated reference sub-picture.
