Music, "one of ordinary skill in the art would equate Music’s
'frame differencing advanced processing/compression scheme' as
executing 'motion estimation' as defined by Gobert."
We have reviewed the disclosure of Music, paying
particular attention to the passages relied upon by the
examiner, and we find that the teachings of Music would not
have been suggestive of using the disclosed bit-width
truncation feature in the field of motion estimation of video
signals. We are in general agreement with the appellant
(Brief, page 5) that the disclosure of Music is directed
toward digital color components and the compression of digital
color video data (Music, col. 2, line 34 to col. 3, line 45).
Music uses bit-width truncation of RGB color components (col.
4, lines 30-35) for compressing digital color data as opposed
to bit-width truncation for motion estimation of a video
image. We do not find any evidence here that would have been
suggestive of using bit-width truncation as it relates to
Gobert’s motion estimation. We are appreciative of the
examiner’s reliance on column 4, lines 10-35 of Music for its
teaching of reducing the amount of data required to represent
pixels of a picture. However, we find that this teaching is
