Description

In “8.5.5.9 Derivation process for motion vector arrays from affine control point motion vectors”, dHorY and dVerY in equations 8-702 and 8-703 should be swapped and the equations should be modified as follows:

bxWXv = ( ( Max( 0, 4 * dVerYdHorY ) − Min( 0, 4 * dVerYdHorY ) ) >> 11 ) + 9 (8 702)
bxHXv = ( ( Max( 0, 4 * ( 2048 + dHorYdVerY ) ) − Min( 0, 4 * ( 2048 + dHorYdVerY ) ) ) >> 11 ) + 9 (8-703)
