Abstract
A method of and an apparatus for controlling intra prediction for decoding of a video sequence are provided. The method includes, based on a reference line index signaling, to a decoder, a first reference line nearest to a coding unit, among a plurality of reference lines adjacent to the coding unit, applying intra smoothing on only the first reference line, based on the intra smoothing being applied only on the first reference line, applying intra prediction on the coding unit, and based on the intra prediction being applied on the coding unit, applying a position-dependent intra prediction combination (PDPC) on only the first reference line.
