Abstract:
A video coding device receives a bitstream including video data. The device determines an intra-prediction mode subset. The intra-prediction mode subset include intra-prediction modes that correlate to a plurality of reference lines for a current image block and excludes intra-prediction modes that correlate to a primary reference line for the current image block. When a first intra-prediction mode is included in the intra-prediction mode subset, the device decodes the first intra-prediction mode by an alternative intra-prediction mode index. When the first intra-prediction mode is not included in the intra-prediction mode subset, the device decodes the first intra-prediction mode by an intra-prediction mode index. The device presents video data including an image block decoded based on the first intra-prediction mode.

Claim (Index 10):
A method comprising:\n storing, in a memory, a bitstream including image blocks coded as prediction blocks; obtaining, by a processor coupled to the memory, a current prediction block encoded by a Direct Current (DC) intra-prediction mode; determining a DC prediction value to approximate a current image block corresponding to the current prediction block by averaging all reference samples in at least two of a plurality of reference lines associated with the current prediction block; reconstructing, by the processor, the current image block based on the DC prediction value; and displaying, on a display, a video frame including the current image block.
