Abstract
A method for processing a video bitstream is disclosed. The method generally includes the steps of (A) determining co-located motion information for a plurality of co-located sub-blocks in a co-located macroblock of the video bitstream, (B) storing the co-located motion information for (i) at least a first three of the co-located sub-blocks along a left side of the co-located macroblock, (ii) at least a second three of the co-located sub-blocks along a right side of the co-located macroblock and (iii) less than all of the co-located sub-blocks and (C) inferring current motion information for a current macroblock co-located in a different picture from the co-located macroblock using the co-located motion information that was stored.
