the result of using run lengths in the video signal. Thus,
nothing in Music indicates that a reduction in hardware
complexity can be achieved as a result of using bit-width
truncation as the examiner has suggested (Answer, page 6).
The examiner points to the fact that both Gobert and
Music state that their inventions are relevant to the area of
video-conferencing (Answer, page 6). We find that this
acknowledgment would not have suggested the combination of the
teachings of Gobert and Music.
The examiner asserts (Final Rejection, page 4) that Music
suggests the applicability of bit-width truncation to motion
compensation, and, in support thereof, the examiner draws our
attention to column 14, line 60 to column 15, line 15 of
Music. We do not agree. To us, this portion of the Music
disclosure teaches the artisan that further compression of
color video data may be accomplished by the implementation of
these additional methods and in no way reveals to us that it
would have been obvious to one skilled in the art to use
Music’s bit-width truncation feature in the pixel comparison
method of Gobert for the purpose of estimating movement in an
image produced by a video signal.
