ABSTRACT:
A device for reproducing digitally presented video pictures includes a restoration circuit for restoring erroneous picture elements. To this end a reference sub-picture is composed from the erroneous picture elements and non-erroneous picture elements, the erroneous picture elements being completely enclosed by the non-erroneous picture elements. The erroneous picture elements are subsequently replaced by zero picture elements. Each picture element is then considered as a sum of weighted versions of picture elements which form part of a prediction field. The set of prediction coefficients associated with this prediction field is obtained by minimizing a prediction coefficient function. This operation is performed for different prediction fields and the restoration process is continued in known manner, this continuation being based on the prediction field yielding the smallest value for the prediction coefficient function.
