Appeal No. 2003-2127
Application No. 09/976,226
The examiner’s characterization that the weights produced by
the motion estimator 118 and supplied by the operation of switch
109 serve as “motion indices to the motion vectors” (answer, top
of page 4) is amply supported according to the teachings of
Lavagetto as well. There are numerous instances in this
reference where the motion vectors are stated to have
“corresponding optional weights” (see the bottom of column 2;
column 7, lines 20 through 26; column 13, lines 19 through 26 and
column 18, lines 17 through 24).
Moreover, from our study of this reference, we are
independently persuaded by other teachings of the anticipatory
nature of the representative subject matter of claim 1 on appeal.
The discussion of the prior art in the Background of the
Invention at columns 1 and 2 of Lavagetto indicates that motion
vectors and weighting factors are known to be “quantized or
encoded as appropriate for transmission or storage.” (column 2,
lines 43 through 47).
A second basis also exists according to the discussion in
paragraph bridging columns 5 and 6, which teaches that the motion
estimator produces motion vectors which are supplied to the
motion compensator 128 through switch 108 and eventually provided
