FIELD: physics.
SUBSTANCE: invention relates to means of performing prediction for encoding or decoding. Subsections are oriented horizontally or vertically and may use wide-angle modes different from those of the video unit from which they originate. Reference readings for a subsection are samples of a video block when reference samples for a subsection are unavailable, for example, due to direction. When the subsection is square, normal intra-frame prediction directions are used. Reference samples can be used from the block above and to the right of the video block or to the left and below the video block using mapping along the prediction direction, vertically or horizontally.
EFFECT: providing more efficient encoding with respect to subsections when non-square subsections have a size ratio different from their video block.
