14. A method implemented by a video coding device, comprising:
determining a value of a reference line index of a coding unit;
determining an intra-prediction mode from a list of most probable modes when the value of the reference line index indicates an additional reference line;
encoding the coding unit into a bitstream based on the intra-prediction mode; and
storing the bitstream in a memory of the video coding device.
