an encoding mode of said DCT coefficient block. Appellant also
shows that independent claims 1 and 20 positively recite this
limitation. See pages 8 and 9 of Appellant's brief. Appellant
points out that Yonemitsu merely provides an additional
processing function at a decoder for correcting prediction errors
produced. The basis functions used within the Yonemitsu process
are standard basis functions. Appellant argues that there is no
disclosure or suggestion within Yonemitsu of any adaptation of
basis functions, much less the claimed adaptation of basis
functions in response to an encoding mode of a DCT coefficient
block. See pages 10-12 of Appellant's brief.
Upon our review of Yonemitsu, we find that Yonemitsu does
teach an IDCT circuit 113. Also, we find that Yonemitsu teaches
that the IDCT circuit 113 performs an inverse transform to
produce 4x4 pixel data groups. See column 17, line 61 through
column 18, line 8. However, we fail to find that Yonemitsu
performs IDCT using modified basis functions versus the standard
basis functions in response to an encoding mode such as the frame
mode. Therefore, we fail to find that Yonemitsu teaches
transforming, according to an inverse discrete cosine transform
(IDCT), said resized DCT coefficient block to produce said pixel
block having said second resolution, said step of transforming
