converter of Faroudja is not a converter, as required by the
instant claims. That is, the converter of Faroudja is a
conventional standards converter (see column 6, lines 51 et seq.)
which converts a 525-line NTSC video source into a 625-line
progressively scanned video signal. While resolution may be
improved, the converter 12 of Faroudja is not one that converts
standard definition formatted data to a format compatible with
high definition formatted data.
The examiner urges that “a converter which processes and
outputs a signal which is progressively scanned and has more
lines, i.e. more picture information, or a higher resolution,
than its input, is in fact a high definition signal” (answer-page
5).
We agree with appellants that the terms “standard
definition” and “high definition” have specific meanings to the
skilled artisan. While it is true that Faroudja converts to a
higher resolution and high definition does have greater
resolution than standard definition, it does not follow that
merely because Faroudja converts from a 525-line signal to a 625-
line signal, this is a conversion to high definition. High
definition systems have 720 or 1080 lines of resolution and the
artisan would have understood this and would not have considered
