Appeal No. 2003-2031
Application 09/225,193
Appellants further point out that “encode bit rate”, as
understood in the art refers to a rate of delivery of compressed
data, in units of bits per seconds, from an encoder to a
receiving device, such as a buffer. Appellants point out that
Lee teaches that the encoding is subject to a fixed bit rate
constraint. In column 21, lines 28 through 32, Appellants argue
that there is no teaching or suggestion by Lee that the bit rate
itself varies between GOPs. Appellants further point out that
Lee does teach that the bit allocation scheme varies. Appellants
argue that bit allocation refers to the number of bits allocated
to code in an individual segment of an input video in order to
maintain a bit rate. Appellants argue that Lee teaches that the
variation in the value “x” permits the bit rate between GOPs to
be constant by allowing for variation in the bit allocation
scheme between individual GOPs. See pages 11 through 13 of the
brief.
The Examiner points out that Linzer does not disclose
adjusting the at least one encoded bit rate for at least one
stream of multiple streams of video frames only upon the
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
