together. The only feature of representative independent claim 1
on appeal disputed by appellant is the language “controlling the
quantization parameter of the basis of the motion vector.” In
relation to figure 1 and the statements made at Lavagotto’s
column 7, lines 52 through 56, appellant asserts that only the
weights from the motion estimator 118 in this figure are
quantized by quantizer 130 and not the motion vectors themselves.
As noted by the examiner at the bottom of page 3 of the
answer, the multiplexer and buffer 117 provides feedback signals
to the quantizer 130 thus indicating that it is adaptive and
therefore varies a quantization step or size such as to provide a
quantization parameter to regulate the bit amounts to be coded by
VLC 116 in Figure 1. We agree with the examiner’s views that
this quantizer 130 is in part responsive to the weights provided
by motion estimator 118 as illustrated in figure 1. From our
study of Lavagetto, we agree with the examiner’s views at the top
of page 4 of the answer that these weights supplied by the motion
estimator 118 serve as “motion indices to the motion vectors.”
We therefore agree with the examiner’s conclusion that “Lavagetto
sufficiently discloses the step of ‘controlling the quantization
parameter on the basis of the motion vector’ as claimed.”
