The invention is related to prediction of a lost or damaged block of an enhanced spatial layer frame. A method for predicting a lost or damaged block of an enhanced spatial layer frame comprises the steps of determining an adjuvant frame in the enhanced spatial layer by help of reference information from a lower spatial layer frame corresponding said enhanced spatial layer frame, generating an information reduced block by help of said adjuvant frame and predicting the lost or damaged block by help of the information reduced block. The reference information of the corresponding lower spatial layer frame can be decoded independently from any lower spatial layer reference frame and the adjuvant enhanced spatial layer frame is already decoded. Thus, the computational effort is reduced. By generation of the information reduced block the prediction is made smoother which makes it less vivid and therefore less salient to a user.
