Appeal No. 2003-0556
Application 09/185,248
Bergher, for example, has more compelling teachings than
realized by the examiner as they apply to the subject matter of
representative independent claim 1 on appeal. There appears to
be no real dispute that the Dolby AC-3™ and MPEG-2 audio data are
in a compressed format (claim 19 on appeal) or otherwise known to
be in a "perceptually based" format. Each of these types of
formats are clearly decoded into a common data stream thus
appearing to indicate that it was known to receive a first audio
data stream in a first perceptually based format and decoding it
into a (linear) pulse code modulated format, and "obtaining" a
second audio data stream through its corresponding process since
the integrated circuit chip of Bergher is taught to provide
plural input channels of at least these two types of compressed
audio information. The discussion of the input data processor at
the first column of page 571 suggests not only decoding of the
information into a common audio bit stream by removing all of the
extra buffering digital information, but also to apparently
linearize it in order "to give consistent data to the DSP core"
of Figure 1 at page 569 to process. In a similar manner, the
teachings at the top of column 1 at Bergher's page 571 seems to
indicate not only the use of a CODEC, the idea of interleaving
