Abstract:
A method for video decoding includes determining whether an angular intra prediction mode for a current block is a wide angle mode that is spaced apart from a vertical mode and a horizontal mode by an angular distance that is more than a predetermined threshold. The method further includes, in response to the determination that the angular intra prediction mode is the wide angle mode, determining a non-wide angle mode that corresponds to the wide angle mode, the non-wide angle mode being spaced apart from the vertical mode or the horizontal mode by an angular distance that is less than or equal to the predetermined threshold. The method includes determining whether a coding tool is specified for the determined corresponding non-wide angle mode, and, in response to the determination that the coding tool is specified for the determined corresponding non-wide angle mode, using the coding tool in a decoding process.

Claim (Index 10):
A video decoder for video decoding, comprising:\n processing circuitry configured to:\n determine, for a current block that is a non-square block, whether an angular intra prediction mode for the current block is a wide angle mode that is spaced apart from a vertical mode and a horizontal mode by an angular distance that is more than 45 degrees, the vertical mode aligned with a vertical axis of the current block, the horizontal mode aligned with a horizontal axis of the current block, \n in response to the determination that the angular intra prediction mode is the wide angle mode, determine a non-wide angle mode that corresponds to the wide angle mode, the non-wide angle mode being spaced apart from the vertical mode or the horizontal mode by an angular distance that is less than or equal to 45 degrees, \n determine whether a coding tool is specified for the determined corresponding non-wide angle mode via access to a look-up table (LUT) that provides an indication, for each non-wide angle mode, whether the coding tool is specified, and \n in response to the determination that the coding tool is specified for the determined corresponding non-wide angle mode, perform intra prediction for the current block using (i) at least one reference sample corresponding to the angular intra prediction mode that is the wide angle mode and (ii) the coding tool.
