same clock period P, but with a 180E phase shift. When the
two A/D converter outputs are combined an effective sampling
period of P/2 is obtained (see Figure 3). The standard
definition mode requires only one A/D converter with a
sampling period of P. Thus the output of the two A/D
converters is the same and redundant in the standard
definition mode (see Figure 4). Since the Examiner is relying
solely on the disclosure of Masumori’s standard definition
operating mode, only one A/D converter is required. Hanmura
is a cumulative teaching of the need for only one A/D
converter in such a mode.
Appellants argue that the combination of Masumori and
Hanmura does not provide the claimed enabling of two adjacent
rows to receive the same data simultaneously (brief-middle of
page 4).
We agree with the Examiner that this is taught by
Masumori operating in the standard definition mode. We note
that at column 6, lines 54-66, Masumori states that (with
respect to Figure 2) in the standard definition mode gate
lines 1 and 2 are simultaneously driven and data of the same
