Appeal No. 2000-0128
Application 08/590,722
OPINION
We reverse.
In accordance with representative independent claim 1 on appeal a “postfilter
parameter” is determined in the encoder “wherein said postfilter parameter is determined
based on the signal-to-noise ratio (SNR) between the encoded video image and the input
video image.” Corresponding features are recited in independent claim 10 on appeal.
We reverse because we agree with the appellants' arguments at page 4 of the brief
that Normile does not contemplate postfiltering decoded video images based on the
number of coding errors made by the encoder simply because the Normile process does
not determine the SNR between coded and uncoded images. We have studied in detail
the teachings at columns 7 through 10 or Normile on which the examiner bases the
rejection of this portion of the subject matter of the claims on appeal. SNR determinations
are discussed in the initial lines of column 7 and at the end of column 8, the latter of which
has been specifically referenced by the examiner. The initial lines of column 8 with respect
to the encoding operation and the corresponding initial lines of column 10 with respect to a
decoding operation seem to indicate some sort of postfiltering parameter is encoded and
respectively decoded to communicate to the decoder which areas of an image to
postfilter.
