1. A video decoder using motion-compensated prediction comprising: a predictor configured to predict a first subset of parameters of a plurality of motion parameters defining the motion-compensated prediction of a predetermined region of a picture of a video to acquire a prediction for the first subset; a reconstructor configured to reconstruct the first subset of parameters from the prediction for the first subset and residual information for the first subset comprised in a data stream, to acquire a reconstruction of the first subset, wherein the predictor is configured to predict a second subset of parameters of the plurality of motion parameters, being disjoint from the first subset using the reconstruction of the first subset, to acquire a prediction for the second subset.
