In JCTVC-H1003_dK, motion vector is treated as an integer value even though it sometimes shows half or quarter pel position. However, a scaled motion vector is treated as a floating value in expression (8-138), (8-146) and (8-156). It should be modified to integer value such as below. And, there is one typo in expression (8-146) (mvLXA should be replaced with mvLXB).

expression (8-138)

original

mvLXA = Clip3( -8192, 8191.75, Sign( DistScaleFactor * mvLXA ) * ( (Abs( DistScaleFactor * mvLXA ) + 127 ) >> 8 ) ) (8-138)

modified

mvLXA = Clip3( -32768, 32767, Sign( DistScaleFactor * mvLXA ) * ( (Abs( DistScaleFactor * mvLXA ) + 127 ) >> 8 ) ) (8-138) expression (8-146)

original

mvLXB =Clip3( -8192, 8191.75, Sign( DistScaleFactor * mvLXA ) * ( (Abs( DistScaleFactor * mvLXA ) + 127 ) >> 8 ) ) (8-146)

modified

mvLXB =Clip3( -32768, 32767, Sign( DistScaleFactor * mvLXB ) * ( (Abs( DistScaleFactor * mvLXB ) + 127 ) >> 8 ) ) (8-146) expression (8-156)

original

mvLXCol = Clip3( -8192, 8191.75, Sign( DistScaleFactor * mvCol ) * ( (Abs( DistScaleFactor * mvCol ) + 127 ) >> 8 ) ) (8-156)

modified

mvLXCol = Clip3( -32768, 32767, Sign( DistScaleFactor * mvCol ) * ( (Abs( DistScaleFactor * mvCol ) + 127 ) >> 8 ) ) (8-156)

(actual version dK)

3.49 inter prediction: A prediction derived from only data elements (e.g. sample value or motion vector) of reference pictures other than the current decoded picture.

The inter prediction may also derive motion data from spatial neighbours.

(actual version dK)

5.9 Each syntax element is described by its name (all lower case letters with underscore characters), its one or two syntax categories, and one or two descriptors for its method of coded representation.

In HEVC, we do not have syntax category now and there is only one descriptor.
