Method and apparatus for intra prediction mode

A method of video decoding, the method comprising:

• receiving a video bitstream including coded information of a current picture and a reference picture of the current picture;
• determining whether directional padding is applied to a padding area that is outside and adjacent to a boundary of the current picture;
• determining a padding direction of the directional padding based on a direction of an intra prediction mode derived from one of a boundary block within and adjacent to the boundary of the current picture and a motion compensation (MC) block in the padding area;
• and
• padding a portion of the padding area based on a plurality of samples in the current picture along the padding direction.

A method of video decoding, the method comprising:

• receiving a video bitstream including coded information of a current block in a current picture, the coded information indicating a prediction mode of the current block that is associated with a list of most probable modes (MPMs) that is generated based on first type of prediction information and a list of most dominant modes (MDMs) that is generated based on a second type of prediction information;
• determining the list of MDMs that includes a plurality of candidate MDMs based on a reference region of the current block;
• and
• reconstructing the current block based on at least one of (i) a candidate MDM in the plurality of candidate MDMs in the list of MDMs and (ii) a candidate MPM in the list of MPMs.
