Abstract: Actually rendered portions of a renderable portion of a first view of a multi-view signal are introduced into a prediction loop of a multi-view encoder to form a reference signal for the block-based prediction of the encoder's view predictor may improve the prediction and thereby increasing the coding efficiency. The introduction may be performed by completely inserting the renderable portion into the prediction loop to form new reference pictures with their own reference picture indices in addition to reference pictures obtained by the reconstructed version of the multi-view signal of the block-based prediction. Alternatively, the actually rendered portion may be introduced into the prediction loop completely, but with replacing the normal prediction reference signal, i.e. the normally reconstructed signal as obtained by block-based prediction. Alternatively, it may be signaled within the data stream which portions of the renderable portion are used to replace respective portions in the normally reconstructed signal.
