When the left direction among the search range is specified as invalid (Search Left) by SKILL
information when the horizontal search range is ±7.5, M65727 invalidates the following vectors.
[integer-pel precision vector]
The vector, whose horizontal component is negative, is invalidated.
[half-pel precision vector]
When the vector, whose horizontal component is zero, is selected as best integer-pel precision
vector, the half-pel vector, whose horizontal component is negative, is
In case when SKILL information specifies the right direction among the search range is invalid
(Search Right) when the horizontal search range is ±7.5, M65727 invalidates the following vectors.
[integer-pel precision vector]
The vector, whose horizontal component is positive, is invalidated.
[half-pel precision vector]
When the vector, whose horizontal component is zero, is selected as best integer-pel precision
vector, the half-pel vector, whose horizontal component is positive, is
Moreover, if both left and right directions among the search range are made invalid at the same time
by SKILL information (Search Left and Right) when the horizontal search range is±7.5, M65727
invalidates the following vectors.
[integer-pel precision vector]
The vector, whose horizontal component is positive or negative, is invalidated.
[half-pel precision vector]
The half-pel vector, whose horizontal component is positive or negative, is invalidated. As a
result, the selected motion vector has a zero as a horizontal component. Therefore, if search top,
search down, search left, and search right are specified at the same time during the horizontal
search range is ±7.5, only (0, 0) vector can be selected.

invalidated.
When using ±15.5 or more as the horizontal search range, if SKILL information specifies that the left
direction among the search range is invalid (Search Left), M65727 invalidates the following vectors.
[integer-pel precision vector]
No vector is invalidated.
[half-pel precision vector]
When the vector, whose horizontal position is most left in a search range of the current execution
cycle, is selected as the best integer-pel precision vector, the half-pel vector, whose horizontal
component is negative, is invalidated.
When SKILL information specifies that the right direction among the search range is invalid(search
right) using ±15.5 or more as the horizontal search range, M65727 invalidates the following vectors.
