Claim 0:
1. A method for decoding video data comprising one or more processors, the method comprising:
(a) receiving a bitstream indicating how a coding tree unit was partitioned into a plurality of coding units according to a partitioning structure that allows nodes to be split according to a partitioning technique, where said partitioning structure allows a node to be split into a plurality of rectangles;
(b) selectively selecting only one of either,
(i) selecting a first main reference line, where said first main reference line is a first main reference line next adjacent to said coding unit above said coding unit, and selecting a first side reference line, where said first side reference line is a first side reference line next adjacent to said coding unit left of said coding unit; or
(ii) selecting a second main reference line, where said second main reference line is a second main reference line next adjacent to said first main reference line above said coding unit, and selecting a second side reference line, where said second reference line is a second side reference line next adjacent to said first side reference line left of said coding unit;

(c) wherein, (i) a combination of said first main reference line next adjacent to said coding unit above said coding unit and said second side reference line next adjacent to said first side reference line left of said coding unit is not permitted, and (ii) a combination of said second main reference line next adjacent to said first main reference line above said coding unit and said first side reference line next adjacent to said coding unit left of said coding unit is not permitted;
(d) wherein, (i) a combination of said first main reference line next adjacent to said coding unit above said coding unit and said second main reference line next adjacent to said first main reference line above of said coding unit is not permitted, and (ii) a combination of said first side reference line next adjacent to said coding unit left of said coding unit and said second side reference line next adjacent to said first side reference line left of said coding unit is not permitted;
(e) based upon at least one intra direction mode generating a prediction for said coding unit based upon at least a portion of said selected one (b)(i) and (b)(ii).
