INTRA-PREDICTION WITH MULTIPLE REFERENCE LINES

Title:

INTRA-PREDICTION WITH MULTIPLE REFERENCE LINES

Document Type and Number:

WIPO Patent Application WO/2018/205950

Kind Code:

A1

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.
