Appeal No. 1998-1339
Application 08/024,305
provide respective coded versions thereof, and (2) a selection
means or a selector which selects one of the scanning patterns
which produces efficient sub-block coding.
On page 4 of the answer, the examiner states:
Gharavi does not disclose a selection means for
“simultaneously” selecting one of the scanning
patterns which produces efficient coding and a
scanning mode selector for selecting a scanning mode
in which a number of bits produced from a start to
an end of a sub-block is minimized as specified in
claims 1, 6, and 10. In contrast, Gharavi discloses
using different scanning patterns (figs. 7a-7c) at
sub-block level to maximize bit efficiency (col. 6,
lines 24-31). Furthermore, Gharavi suggests that
compression efficiency can be further improved by
adaptively scanning the reconstructed block (see
col. 7, lines 37-44). In other words, a selection
of the scanning pattern which will yield maximum
coding efficiency is implied.
In addition, Gharavi fails to teach the scanning
pattern selecting means as claimed, however, the
suggestive teaching that the scanning patterns can
be adaptively scanned to improve coding efficiency
as disclosed in Gharavi implicate that a means for
selecting one of the three scanning patterns is
essentially necessary. Therefore, one skilled in
the art having Gharavi before his/her would have
been motivated to further explore the suggestive
teaching of an adaptive scanning method as disclosed
in Gharavi to come up with an improved means and
method steps of producing a plurality of scanning
patterns and adaptively selecting one which will
yield the highest coding efficiency as claimed.
