Appeal No. 1997-1240
Application 07/881,753
signal having a same format as the high definition signal and
the same field frequency as that of a standard television
signal as recited in Appellants' claim 1.
The Examiner responded to Appellants' above argument
on page 9 of the answer stating that the claimed high
definition processing means for applying to the double rate
signal a scanning line conversion processing to convert the
same into a signal having the same format as that of a high
definition signal
to be an inherent characteristic of Katsumata's figure 11,
component 1103, because Katsumata's reference discloses that
the signal outputted from figure 11, component 1103, to be a
double rate signal as well as a high definition signal as
clearly specified in Katsumata's column 15, lines 7 through
12. In column 15, lines 7 through 12, Katsumata states:
The double scanning 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 inter- polation processing so as to
attain high definition.
