Appeal No. 2002-0489
Application 08/831,731
chip is attached to video circuitry external to the video
decoder. Since the horizontal sync signal HS is output from the
circuit (Fig. 2, pin 38), the signal HS is received by the
external circuitry of which the VIP integrated circuit is a
component. The rejection of claim 2 is sustained.
Claims 31-34
Appellant contests (Br14-15) the examiner's statement that
"[i]t is well known that the horizontal sync is used as a
simulated burst gate signal" (FR9). Appellant argues that this
statement has been strongly traversed and the examiner has not
made of record any reasonable support for his view (Br15). It is
argued that a horizontal sync pulse is separate from a burst gate
signal (Br15).
The examiner responds that the book Television Engineering
Handbook, edited by K. Blair Benson (McGraw-Hill, Inc. 1986), of
record, "teaches that it is [sic, was] well known in the art the
technique of utilizing the horizontal sync pulse signal to derive
(simulate) the burst gating pulse signal" (EA10). It is argued
that although separate horizontal sync and burst gate signals are
used, the "simulated" burst gate signal can be represented by the
horizontal sync rather than by an external decoder (EA10-11).
We are not convinced by the examiner's reasoning, as stated.
Benson teaches that the gating pulse can be derived from the
