definition motion vectors in the neighborhood of blocks in which
to filter, following a down conversion scheme. See page 9,
section 4.1, page 10, section 4.2 and page 11, section 4.3. We
also find that Vetro provides adequate motivation for this
combination by suggesting that the resulting filtering scheme
minimizes the mean square error between a reference block and a
block obtained through the low resolution MC to thereby perform a
motion compensation on macroblocks a, b, c, and d to yield h. See
page 4, section 2. Next, we find that Ng complements Vetro’s
teachings by suggesting the use of motion vectors in a motion
compensation scheme following the down-sampling of HDTV
compressed digital images. We also find that Ng provides
motivation for this combination by indicating that the suggested
approach offers the advantages of reduced memory, slightly
enhanced resolution and lessened computational speed
requirements. See column 6, lines 50-54. Additionally, we find
that Bose further reinforces the Vetro and Ng combination through
its explicit teaching of a motion vector in a motion compensation
scheme for digital video, wherein the motion vector specifies a
relative vertical or horizontal distance from a reference data to
a macroblock. We also find that Bose provides proper motivation
