(page 4, para. 33) band 163 has eight digital channels. Hodge
further discloses (id.) that among the digital channels, two
could be Internet protocol channels 167 and 168 which would be
fed to encoders to produce MPEG bit streams which would fit
within the frequency allocation of the digital channel. It is
additionally disclosed (page 4, para. 36) that the Internet
Protocol of the Ethernet packets are converted to MPEG2 compliant
encapsulation packets, and that the invention converts the return
Ethernet data to MPEG bit-streams which can be interlaced with
video program material and separated by a decoder in the set-top
box. Each set-top box has a decoder which separates audio from
video and can separate Internet data for display or presentation
in an appropriate format.
From the disclosure of Hodge, we are in agreement with the
examiner (answer, page 4) that “Hodge teaches dividing the
Internet protocol packets into MPEG-2 signals wherein the process
utilizes the 23 least significant bits, which equates to
preserving the standard Internet protocol.” We further agree
with the examiner (answer, page 5) that Hodge is silent on using
the MPEG digital format. Additionally, as noted by the examiner
(answer, page 11), Hodge discloses Internet Protocol (IP) over
MPEG.
