Bob,
Actually most modern houses that receive cable/satellite services do have a place of entry where all
the coax of each receiver/room would join the rest to meet the external coax of the service, that is
usually on the basement and is the place for multiswitches on satellite or splitters on cable.
Traditionally one of those coax feeds will go from the switcher to the main HT room, with the signal
flowing in that direction.
If the server will be located on that HT room, and the system would require the server to be the
only entry point one could make the installation so the external service feed goes directly to that
room/server, and that server would use the wire above to send the output to the joining place in the
basement (in other words, using the coax in the opposite direction so it will meet all the other
coax wires in the basement).
However, Ucentric mentioned that servers and clients could be located on any place of the network,
which means it could be like a "star" network. A daisy chain network (like 1394 for example) would
actually require the rewiring that you mention because the rooms would receive their coax from other
rooms, not from the central place on the basement.
If Ucentric is planning to use the same approach "as their never in production 580 model" of
server/clients, the one they were doing for Voom, (and I do not see why not, all the effort was
done, even with the MPEG-4 upgradeability by just changing the card), they will be competing with
the other cable approach demo by Scientific Atlanta server using also coax but with the added
feature of a Hi Def DVD into the unit, in addition to the HD DVR, that unit was in prototype at CES
2005 (pages 11 and 93) and expected to be released in late 2005, if one can trust manufacturer
projections.
In the 580's case the clients could also be HD (with some limitations in their number), and all will
be able to control the server from their location, in fact the star coax approach was one of the
selling points of Ucentric because most modern houses are already prewired, and with the addition of
an attic coax for OTA antenna. Complete coverage of how the system of server/clients work was on
2004 and 2005 reports.
Panasonic and the others have already demo their wired/wireless HD networks as far back as 2002, the
wireless XtremeSpectrum solution is one example, check the specs and chip photo on page 76 on the
CES 2003 report (free), here is some excerpt:
"XtremeSpectrum
-----------------
The company showed its HDTV capability, introduced in June 02, as the only, claimed by the company,
wireless technology that can handle multiple streams of MPEG-2 video, and multiple HDTV streams,
with the same performance as a wired system. The system uses ultra-wideband Trinity chipset, and
has an aggregated data-rate of 100 Mbps."
Here is JVC and Panasonic back then (almost 3 years ago):
JVC (wired/wireless in short distance)
----
The company showed a mockup of the MediaBank networking server that is expected to distribute video
over 802.11b network using MPEG-4 compression. The company showed an optical wireless HDTV image
transmission system, $N/A, TTM N/A, 1.25 Gbps for uncompressed images in HD, it uses laser diodes
and high-sensitivity avalanche photodiodes, 10 meters distance for wireless home-theater, automatic
adjustment between transmitter and receiver, and eye-safe technology.
Panasonic
---------
The company showed a wireless HD media network prototype based on 802.11a to transmit several
simultaneous DTV signals at high-speed high-quality 54Mbps bandwidth using a 5GHz channel (1 HD
channel at 24 Mbps or 3 SD channels at 24 Mbps). The system enables remote control AV equipment
from another room, simultaneous video transmission, and high-speed Internet connection. Check the
server and clients photos on pages 75 and 76 of the 2003 CES report.
In other words, they have been working at that level of bandwidth for quite a few years already.

This problem is a little different than a general networking install. By
default, assume the server will sit with the primary TV or HT location and
the clients will be lesser used satellite bedroom/family room/den locations.
Since most multi-box cable or DBS installs today don't have existing cable
direct from the server site to the client sites in the home, it becomes a
significant issue. Somebody will be doing some attic or crawl space work to
make it happen, is my guess.
Perhaps you're referring to general network protocols?
