![]() TM_PRED (TrueMotion prediction): It uses pixel P above & to the left of the block.DC_PRED (DC prediction): It fills the macroblock with a single value based on the avg of the pixels in the row above A (V_PRED) & the column to the left of L (H_PRED).V_PRED (vertical prediction): It fills every row with the macroblock with the generated copy of the above row denoted by A.H_PRED (horizontal prediction): It fills every column with the macroblock with the generated copy of the left column of the same denoted by L.These macroblocks share the following 4 common intra-prediction modes : The image frame is “key” in the sense that it only uses the pixels already decoded in the immediate spatial neighborhood of each of the macroblocks & tries to recover the unknown parts and uniquely identify the macroblock. ![]() ![]()
