Appeal No. 96-4011
Application No. 07/996,525
This is an appeal from the final rejection of claims 1
through 4, 6, 8 through 26, 28 and 31 through 38. Claims 29 and
30 are objected to as being dependent upon a rejected base claim,
but would be allowable if rewritten in independent form including
all of the limitations of the base claim and any intervening
claims. In a first Amendment After Final (paper number 20),
claims 3, 4 and 28 were amended, and in a second Amendment After
Final (paper number 23), claim 3 was further amended.
The disclosed invention relates to a video processing system
for a composite video signal that comprises a luminance signal
and a chroma carrier modulated with chrominance information.
Claims 1 and 8 are illustrative of the claimed invention,
and they read as follows:
1. A system for processing video information including a
luminance signal and a chrominance signal, which said chrominance
signal comprises a suppressed chroma carrier having a phase that
at corresponding horizontal spatial locations alternates from
line to line within each field and being modulated with
chrominance information, and having synchronizing signals
included within at least one of said luminance and chrominance
signals, said system comprising:
means responding to at least one of said synchronizing
signals for generating a phase alternated carrier having a phase
that at corresponding horizontal spatial locations is not
different from line to line within each field, but does alternate
from field to field;
means for modulating said phase alternating carrier in
accordance with an auxiliary signal to generate an auxiliary
modulation result; and
