Appeal No. 2002-0764
Application No. 09/131,960
to the examiner, “Golimn [sic, Golin] discloses a system and
method for coding a video signal comprising a sequence of
subsequences of video frames (Fig. 1, element 102), the apparatus
comprising: means for determining a coding quality measure (Fig.
1, element 110) for one or more of the video frames; means for
selecting (Fig. 2, element 202) a particular one of video frames
based on the coding quality measure; and means for coding (Fig.
1, element 116) the selected video frame as specified in claims 1
and 15.”
Golin discloses a method of encoding a sequence of images
via a two-pass procedure. During the first pass of the sequence
of images 102 (Figure 1), the method determines the complexity1
110 of each image in the sequence of images (column 4, lines 3
through 14), and after the first pass of the sequence of images
has been completed, the same sequence of images undergoes a
second pass wherein the sequence of images is compressed using
the determined complexity value (column 4, lines 47 through 56).
Appellants argue (brief, page 5) that Golin does teach
“selecting a subset of the video frames for coding and allowing
1 Complexity is defined in Golin as “a measure of the difficulty of compressing an image;
that is, the number of bits necessary to obtain acceptable image quality” (column 1, lines 55
through 57).
