...fter each component that should be multiplied by 16 and added to the first MV value. ...a bit flag is read to determine whether we'll decode one or four MVs, then MV components are decoded.

* for all 8x8 blocks in tile get codes for block type, MV flag and (if MV flag is true) motion vector

Inter block with coded MV has the prediction unit type (2 bits for 8x8 block, 3 bits otherwise) and m Inter block without MV or skip block has just skip candidate coded as <code>0</code> = 0, <code>10
