Appeal No. 1999-2449
Application No. 08/745,584 Page 5
Appellants assert (brief, page 7) that Gonzales performs
motion compensation prediction (MCP) at two or more
resolutions, but that all MCP units share the same
(appropriately scaled) motion vector data, and that Gonzales
preserves the motion vector (appropriately scaled),
corresponding to any resolution. It is argued ( id.) that
"[n]owhere does Gonzales describe the two searches in the steps
of Appellants' claims 1 and 5 of (1) performing a search using
down sampled data and (2) performing a refinement search around
the offset of the motion vector found in the first search using
non-downsampled data." Appellants further argue ( id., page 8)
that while Gonzales shows coding at two or more resolutions
using a single (scaled) motion vector, that Gonzales does not
describe using the motion vector from one search in a
subsequent refinement search, and that Gonzales performs no
subsequent search at all, but instead encodes data at multiple
resolutions using a single motion vector. With respect to
independent claim 15, appellants assert that Gonzales does not
describe performing a hierarchical first search, and a
refinement second search around the offset of the best match,
and does not describe any apparatus for performing the two
searches.
The examiner responds by asserting (answer, page 8) that:
