Appeal 2007-2921
Application 09/951,452
have been canceled. We have jurisdiction under 35 U.S.C. § 6(b) to decide
this appeal. We affirm.
The Invention
Appellant invented a data recording method and apparatus for
compressing digital data bands. The invention uses a quantizer that encodes
the incoming digital data to output quantized data including a quantization
error that is subsequently recompressed and added to the compressed data.
(Specification 8.)
An understanding of the invention can be derived from exemplary
independent claim 1, which reads as follows:
1. A compression data recording apparatus for compressing a digital
signal, comprising:
a filter configured to divide an input signal into a plurality of bands; and
a mechanism configured to perform compression and a decompression of
said divided bands,
wherein said compressing and decompressing mechanism is arranged at a
plurality of stages in a layer manner and said mechanism comprises an
encoder configured to encode the information in said divided bands and
output an error based on the results of said encoding, said error being
recompressed and added to the compressed data.
In rejecting the claims on appeal, the Examiner relies upon the
following prior art:
