. . . to improve the precision of the motion vector data" and
"refinement of some parameters such as the accuracy of the
motion vectors" refers to a refinement of the motion vector
data.
Appellants respond to the examiner's position (reply brief,
page 2) by asserting that:
Gonzales mentions an additional correction in
only one line of the summary of the invention
section and it is never discussed anywhere else
in the specification. How the additional
correction could be carried out after the lower
resolution vectors are scaled up is not explained
and apparatus for doing so is not provided.
In our view, notwithstanding the fact that Gonzales makes
brief mention of providing additional correction, Gonzales
nevertheless does disclose providing as an alterative,
additional correction at the higher resolution scale to improve
the precision of the motion vector data. With regard to
appellants' assertion that Gonzales does not discuss how the
additional correction should be carried out, the examiner
(answer, page 4) makes broad reference to figures 12a and 12b,
and columns 3, 4, 8, and 12-14) for a teaching of, inter alia,
"conducting a non-down sampled full pixel search using
reconstructed refinement search data around the offset of the
best match macroblock," after construction of the motion vector
of offset between the best match macroblock and the current
