[M4IF Technotes] Question about Quarter-pel Motion Compensation

[Xue Xuhong]

Hi,
In the VLC table for MVD( Table B-12,  in the standard) , it seems that the
"-16", "-15.5"... are in the unit of pel.
which is showed below:
Code                      MVD
0000 0000 0010 1       -16
0000 0000 0011 1       -15.5
0000 0000 0101         -15
...
When the Quarter-pel Motion Compensation is used, if the codes in the
bitstram is 0000 0000 00101, should we get the MVD as
"-16" in pel unit, then transform it to -16*4=64 in 1/4 pel unit?
