Application 07/881,753
This is a decision on appeal from the final rejec-
tion of claims 1 through 16, 18, 20 and 22, all the claims
pending in the present application. Claims 17, 19 and 21
have been cancelled.
The invention relates to a video signal recording
and/or reproducing apparatus which is capable of recording
and/or reproducing both a high definition signal and a stan-
dard television signal such as the NTSC signal. On page 10 of
the specification, Appellants disclose that figure 1 shows an
input terminal 10 of a standard television signal, NTSC sig-
nal. Appellants disclose that this NTSC signal is converted
to a pseudo HD signal by the interpolation and rate doubling
circuit 200 and the high definition processing circuit 300.
On pages 12 through 14, Appellants disclose that the interpo-
lation and rate doubling circuit 200 produces an ED signal
which has attributes shown in the table disclosed on page 13
labelled column ED SIGNAL. In particular, the table shows
that the NTSC signal is converted from an interlace ratio of
2:1 to an ED signal having an interlace ratio of 1:1. Appel-
