Appeal 2006-3341
Application 10/266,491
Appellants have described this embodiment of their invention in the
following manner:
In other embodiments, the OSD information for the STB is
transmitted out of the STB along the digital transport stream, along
with the HD digital data, via a high speed digital interface, such as
IEEE1394. The HDTV demultiplexes and decodes the digital
transport stream to extract the OSD information for display on the
HDTV monitor. Thus, functions in the STB can be accessed from the
displayed OSD information. Specification 5, last paragraph.
This application is a continuation of application number 09/243,752,
which issued as U.S. patent number 6,490,002 (‘002). The claims in the
‘002 patent addressed an embodiment of the invention using a separate
analog signal path containing the OSD information. In the instant
application, there is a single path containing both the TV signal, and the
OSD information. In the claims under appeal, only claims 28 and 31 indicate
that the OSD information is sent from the receiver in analog form.
In Figure 5 of the Van Der Meer patent we find a device receiving at
least one TV signal in a receiver circuit. The signal is described as a digital
MPEG2 video, audio and graphics signal, the latter being commonly used
for subtitles in television programming.
The Examiner took official notice that the HDTV of claim 222 could
be read on the MPEG2 receiver and display of Van Der Meer. In support of
that official notice, Examiner presented the Auld patent, which states in
column 2, line 33: “The MPEG-2 standard is similar to the MPEG-1
standard, but includes extensions to cover a wider range of applications,
2 Claim 22 reads in relevant part: “A method of displaying information on a
monitor of a high definition television (HDTV)… .
