Appeal No. 2006-1605
Application No. 09/470,741
Invention
Appellants’ invention relates generally to a method and an
article of manufacture having a storage medium and instructions
stored thereon for performing video image decoding, as depicted
in Figure 2. To decode the video image, a compressed video image
is first down sampled in the frequency domain (230). Next, the
down sampled video image is inverse-transformed (220). Further,
the inverse-transformed down sampled image is fed into a motion
compensation module to thereby perform a motion compensation for
the down-sampled image in the spatial domain (210). The motion
compensation includes scaling a motion vector in accordance with
a down sampling ratio, wherein the motion vector specifies the
relative distance of reference data from a macroblock.
Claim 1 is representative of the claimed invention and is
reproduced as follows:
1. A method of performing video image decoding comprising:
downsampling a compressed video image in the frequency
domain;
inverse transforming the downsampled video image; and
performing motion compensation for the downsampled image
in the spatial domain, the performing of the motion compensation
comprising scaling a motion vector in accordance with a
downsampling ratio, the motion vector specifying relative
distance of reference data from a macroblock.
