Abstract

A video decoder for decoding a video from a data stream using block-based predictive decoding, the video decoder supporting a set of primitive prediction modes for predicting blocks of a picture of the video, is configured to predict a predetermined block by a composed prediction signal by deriving, using a collection of one or more primitive prediction modes out of the set of primitive prediction modes, a collection of one or more primitive predictions for the predetermined block, and composing the composed prediction signal for the predetermined block by combining the collection of one or more primitive predictions.
