Claim 14:
15. A non-transitory computer readable medium having instructions stored therein, which when executed by a processor in a video decoder causes the video decoder to execute a method comprising:
determining, 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 in a direction outside of a range of directions that spans a bottom left diagonal direction and top right diagonal direction of the current block;
in response to determining that the angular intra prediction mode is the wide angle mode, determining whether a block size of the non-square block is greater than 32;
in response to determining that the block size of the non-square block is greater than 32, enabling an intra smoothing filter and applying the enabled intra smoothing filter to blocks neighboring the current block to generate filtered blocks; and
performing intra prediction based on the filtered blocks to obtain a characteristic value for the current block.
