Appeal No. 2003-2031
Application 09/225,193
encode bit rate employed in said encoding of at least one
stream of video frames wherein said adjusting only occurs
upon beginning of a new group of frames (GOP) within said at
least one stream of video frames, wherein for said at least
one stream said encode bit rate is constant within each GOP
and is variable between GOPs.
We note that Appellants’ independent claim 33 recites:
computer readable program code means for causing a computer
to effect adjusting at least one encode bit rate employed by
said encoding to encode said multiple streams of video
frames, and wherein said adjusting the at least one encode
bit rate for at least one steam of the multiple streams of
video frames only occurs upon beginning of a new group of
frames (GOP) within said at least one stream, wherein for
said at least one stream of video frames said encode bit
rate is constant within each GOP and is variable between
GOPs.
Finally, we note that Appellants’ independent claim 36 recites:
wherein said at least one controllable encode parameter
comprises at least one encode bit rate, and wherein said
adapting said encoding for at least one stream only occurs
upon beginning of a new group of frames (GOP) within said at
least one stream, wherein for said at least one stream of
video frames said encode bit rate is constant within each
GOP and is variable between GOPs.
Therefore, we find all Appellants’ claims recite encoding of
multiple streams in parallel, with encoded bit rate of one or
more of the stream being constant within each GOP and variable
between GOPs based upon relative changes in the intraframe and/or
interframe characteristics.
