Abstract

The invention relates to a solution for encoding and decoding, wherein an intra prediction direction is determined for a first coding unit; an array of active reference samples is generated for said first coding unit by determining a distance measure between said first coding unit and an array of remote reference samples; by determining a location of at least one remote reference sample of said array of remote reference samples using said intra prediction direction and said distance measure; and by adding said at least one remote reference sample to said array of active reference samples. A block of intra prediction samples is generated using said intra prediction direction and said array of active reference samples.
