speed scanning frequency of an NTSC signal and the scanning
frequency of a MUSE signal. However, in column 15, lines 1
through 14, Katsumata teaches that the double scan speed
conversion circuit 1103 forms interpolation scanning lines
from the output signals of the IDTV processor 1101 and the
EDTV processor 1102, and performs movement adaptation scanning
line interpolation processing so as to attain
high definition. However, Katsumata fails to teach that the
circuit 1103 converts the input signal into a signal having
the same format as that of the high definition television
signal which would be the disclosed MUSE signal. Upon reading
the
disclosure as a whole, one of ordinary skill in the art could
be led to the possibility that, in fact, this is not the
conversion which is taking place but, instead, that the
display is able to accommodate either format. Therefore,
because the Examiner has the initial burden to establish a
prima facie case of obvious- ness, we will not sustain the
Examiner's rejection.
