Abstract
The present invention relates to a method of decoding in a decodera bitstream representing an image comprising: receiving the bitstream; for each block in the bitstream: forming predictions; and adding a respective prediction to each residual sample to form a reconstructed image sample; providing a reconstructed image from the reconstructed image samples; and outputting the reconstructed image; wherein the step of forming a prediction comprises: applying a first directional or non-directional prediction mode to reference samples to form at least a first set of one or more predictions for the current block; and applying one or more subsequent, different, directional or non-directional prediction modes to the same reference samples to form at least one subsequent set of one or more predictions for the current block, where any subsequent directional prediction mode differs from any first directional prediction mode in the spatial direction of prediction.
