Appeal 2007-2921
Application 09/951,452
35 U.S.C. § 102(e)? Particularly, does Park’s disclosure anticipate the
claimed invention given that Park teaches quantizing incoming digital signal
bands to generate multi-layered bitstreams that are subsequently encoded?
FINDINGS OF FACT
The following findings of fact are supported by a preponderance of
the evidence.
The Invention
1. Appellant invented a data recoding method and apparatus for
compressing incoming digital signal bands. (Specification 8.)
2. As depicted in Figure 1, upon receiving digital signal bands
generated from a filter (61) and an analog to digital converter (62), an
encoder (63) quantizes the received bands to output compressed data
including a quantization error. (Specification 27.)
3. The resulting quantization error is further re-compressed in
another encoder (65), and subsequently added to the compressed data. (Id.)
The Prior Art Relied Upon
4. Park discloses a method and apparatus for coding and decoding
audio signals. (Abstract, Title.)
5. As shown in Figure 2, Park discloses a quantizing module (220)
that, upon receiving digital signal bands generated from a filter (200),
outputs quantized data including a quantization noise or error. (Col. 5, ll.
54-67.)3 The ensuing quantized data and quantization error are represented
3 Park states that “[t]he quantizing portion 220 quantizes the signals for each
predetermined coding band so that the quantization noise of each band
