Motion Forward F Code in Picture Layer – forward_f_size – forward_f A B Integer pixels Half-pel – right_half_for a c b d a = A b = (A+B+1)/2 c = (A+C+1)/2 – down_half_for – Bilinear filter C D d = (A+B+C+D+2)/4
Motion Predictor Reset The current macroblock is the first macroblock in the slice. The last macroblock that was decoded contained no motion vector information. – The last macroblock was skipped. – The macroblock_motion_forward was zero.
