Hotel
TV and Audio System
We installed
a custom specified system into this new build 80 bedroom Hotel.
The heart of a Hotel TV system lies tucked away from the guests rooms, usually
in the Communications Room.
This hotel was no different, and we installed the TV Head End system into
one of our 19" rack cabinets.
Cat5e patch
cables are routed to the adjacent racks to connect to the buildings main Structured
Cabling System for distribution to the rest of the Hotel thereby feeding all
the TV screens.
The customer
requested from us a 16 channel TV system, which which we designed and built
specifying 'TV over Cat5' panels from the SCION range, for whom we are dealers.
The SCION equipment gives good quality, reliable results every time we use
it. Each custom install is different and therefore we can tailor the design
and exact components to suit the customer requirements.
Here we
specified a 16 channel input with 96 TV outputs.
All TV sets get the same high quality picture regardless of distance from
the head end.
The picture is composite video with stereo audio on all channels, which originate
from either Sky Satellite or Freeview DTT receivers connected in the equipment
rack.
We also
included a Hotel information channel as part of our system.
This channel give guests information over several active pages, about the
hotel including
telephone nmbers of all the departments, a TV channel line-up list,
pictures of the hotel facilities and all with BBC News 24 TV in one corner
of each page along with sound.
This 'Hotel Information Package' as we like to call it, can be altered and
updated as often as the Hotel manger requires from his desktop computer.
One challenge
that we overcame was to do with a local radio station that they wanted to
distribute around the hotel as another TV channel.
Simple enough in itself, but the radio station is only available as an FM
brodcast, so we needed some picture content to go along with the audio content.
We produced a DVD whcih contained a short film about the radio station (courtesy
of the radio station itself) and overlayed the Radio Station logo with other
text indicating to the guest, that they were listening to a radio channel
etc.
The video feed from a DVD player with this disc plays in a permanent loop
to provide a nice backdrop to the Radio station sound.
All very swish, I must say, and an excellent and professional looking solution
it is as well, and a solution that no doubt we shall be using again.
Satellite
TV Content Delivery System for Re-Broadcast.
We installed satellite
dishes up on the roof of an 8x storey building to receive signals from 3x
different satellites.
13 East, 19 East and 22 West.
Multicore cables fed the signals from the dishes and into a cabinet housing
multi 'IF' amplifiers.
From here the cables continued down to the 3rd floor where the 10 cable backbone
entered into another cabinet (pictured below), which housed a multiswitch
arrangement for distribution to the various satellite receiver points.

And finally, the finished article!
The final part of this particular contract involved the fitting of these broadcast
quality satellite receivers which we supplied custom made to suit the customers
own requirements, (SDI Video output on BNC connectors and Balanced Audio via
XLR connectors).
SMATV Channel Monitoring System.
Viewing figures for TV Channels and Programs.
You
will hear many times each week in the media, how many people watched a particular
program or channel.
This is the system that does it all. We installed this system for the company
who carries out this service here in the UK.
This
system is similar to a tradional SMATV system, it has a dedicated digital
receiver for each TV channel broadcast.
The output from each receiver is fed into a bank of computers for analysis
and processing.
Information is obtained from the polling panel around the UK, and then matched
up.
From the results obtained, the broadcasters (all of them including BBC, ITV,
C4, C5, SKY) know how many people have watched each station at what times
and for how long. Advertising revenue, program popularity etc is calculated
based on the results from this system. The next time you hear the TV viewing
figures mentioned, think of CDI, as we installed all the TV reception side
of this system! ! !
Here are some pictures we took while installing it.
(left pic) Banks of computers and
digitisers which capture the output from the receivers.

note: No there are no mirrors here, those really are rows of SKY receivers!
(just some, not all).

When all the kit turned up, we had to unpack and move it quickly as space
was at a premium!

Installed Pro Broadcast TV Equipment
at BBC Studios
We installed special kit
here at BBC studios to provide another in house TV channel,
used to preview news report productions on VT (Video Tape).
A couple of years later we installed yet another in house channel using the
same kit, but this time connected to a satellite receiver and Satellite dish
on the roof, which we installed for the use of national BBC HQ internal broadcasting
of special events, relayed from London. Both items of equipment can be identified
in this picture by our CDI badge on the kit.

installed using a 'Non Penetrating Roof Mount'
Waterproof
'F' plugs were fitted to the Quattro LNB
Space was very tight
on this particular site, so we installed the SMATV system into a 19"
rack bay.
Satellite receivers were installed at the front of the rack, and all the technical
stuff installed at the back.
In this way everything remained accessible from one side or the other.
Vestigial sideband modulators/filters
fitted into a 19" rack cabinet
Below the
modulators we installed the other Head end Equipment.
A 'non-infra-red' wired remote control was used to program the SKY receiver
control units.
This picture shows how you can fit 16 channels, 2x Power supply units and
a final Broadband Amplifier into one side of a 19inch rack bay cabinet.
There
is space for more channels on the DIN rails if required at a later stage.
This
system feeds 16 digital tv channels to 32 TV's (inc Plasma flat screens) spread
over four buildings!
Moorfields Eye
Hospital
This
installation serves every TV in the hospital including the Patients wards.
Each TV set has 13 channels to choose from.
These pictures
show the main hub of the system which is situated in a dedicated room.
The equipment
is housed in a secure cupboard complete with fan cooling.

Receivers at the top.
Individual channel modulators underneath, and 4 more normal receivers with
decoders on the left.
Monitor TV is part of the installation. With 37 TV channels plus FM radio,
Fibre Optic links to other buildings, separate IRS feeds in each room, makes
this system the ultimate.
You can do no more than this!
A fully
channelised system. Each UHF channel has it's own Filter and Amplifier to
assure clean signals throughout the system.
We installed Fibre optic kit 
at some of the sites where long cable runs were required between buildings.
The advantage of Fibre over Copper cable is negligible signal loss even over
long distances.
You may
notice the similarity of this picture to another one above. They are in fact
completely different sites, but I installed both of them to do exactly the
same job, 37 TV channels distributed to various buildings throughout a private
estate.
This is the finished job again, but with the Fibre Optic Transmitters showing
to the right hand side of the room.
Here is
a busy man, shown making an adjustment to the system. 
How to Build and Install a 3.1Metre
Satellite Dish
First cone
off the immediate area surrounding the build site. Then, build up temporary
ground stand for the dish to sit on while I build it.
Then
Fit the parts of the dish together 
Next complete the web structure by fitting the rim. Now it is ready to fit
the 'petals' that will make up the dish face.
Now
put the dish away inside the building ready for tomorrow when the crane will
come to lift it onto the roof.
Here comes the crane that will lift the dish up onto the roof
A

Here it comes 
Here comes the 3.1Metre satellite dish, looking like the full moon in spring.
Up
on the roof things are getting more exciting as we contemplate our next set
of manoeuvres.
The Dish is lowered by the crane carefully onto it's mounting mast.
Now
all that has to be done is line up this
motorised dish to track the arc, (that is the line of satellites as they appear
in the sky). 
This dish was completed by fitting a Quattro output LNB to feed a rack of
multiswitches down in the communications room. However it is shown here with
a C120 universal LNB which was used to line up the dish using our spectrum
analyser.
IRS Communal TV
Distribution Systems
Where
neatness is the mark of a professional system, CDI exceed.
CDI offer an expert service to customers requiring a reliable and high quality
installation.
A
CDI quality IRS Head End system is shown here after just being installed into
a loft space of a block of flats in London.
As you can see, the cables to each flat and the loop feeds onto the next multiswitch
in the next loft, are yet to be connected.
You
can see the cable that we use is a 'Solid Foam' type, with a 'Crimp on' type
'F' plug.
Quality!

fitted 'F' plug.
Engineer
Installs a Multisat Dish array, used to feed a 9 wire 'Integrated Reception
System'.
Note
the use of a Pro Safety Harness, Climbing Rope, Karabiner, and Ladder tied
to the wall.
Safety
was a particular issue here as the install involved using both hands at once
on the dish, leaving only the feet and the safety gear to suspend the engineer
off the wall at a working height of 30' in the air!

the next pictures!
