    Abstract: A method of controlling residual coding for decoding or encoding of a video sequence, is performed by at least one processor and includes, based on a multiple transform selection (MTS) index indicating that a transform skip mode is enabled for a coded block of the video sequence, identifying an identity transform as each of a horizontal transform and a vertical transform. The method further includes, based on the MTS index indicating that the transform skip mode is not enabled for the coded block, identifying one of a discrete cosine transform (DCT), a discrete sine transform (DST), a Hadamard transform and a Haar transform, as either one or both of the horizontal transform and the vertical transform. The method further includes performing the residual coding of the coded block, using the identified horizontal transform and the identified vertical transform.

    Abstract: A method for decoding a video sequence of a coded video stream, performed by at least one processor, using at least one color palette in a palette mode, each of the at least one color palette including at least one luma value or at least one chroma value, the method including determining whether a current tree structure is a dual tree structure where a luma color plane has a split tree structure that is different from a split tree structure of a chroma color plane; and decoding at least one image of the video sequence using one or more color palettes of the at least one color palette based on the determining whether the current tree structure is the dual tree structure.

    Abstract: A method of performing merge candidate list construction for video coding using at least one processor includes determining a plurality of potential merge candidates; selecting a first potential merge candidate from among the plurality of potential merge candidates; performing a redundancy check by checking the potential merge candidate against a merge candidate included in the merge candidate list; based on a result of the redundancy check, determining whether to insert the potential merge candidate into the merge candidate list; determining whether a redundancy check threshold is exceeded, wherein the redundancy check threshold relates to at least one from among a number of redundancy checks which have been performed, and a number of potential merge candidates which have been checked by the redundancy checks; and based on the redundancy check threshold being exceeded, determining not to perform additional redundancy checks during the merge candidate list construction.

    Abstract: A method and apparatus for selecting an intra interpolation filter for multi-line intra prediction based on a reference line index for decoding a video sequence includes identifying a set of reference lines associated with a coding unit. A first type of interpolation filter is applied to reference samples included in a first reference line, of the set of reference lines, that is adjacent to the coding unit to generate a first set of prediction samples based on the first reference line being associated with a first reference line index. A second type of interpolation filter is applied to reference samples included in a second reference line, of the set of reference lines, that is non-adjacent to the coding unit to generate a second set of prediction samples based on the second reference line being associated with a second reference line index.

    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.
