Signal Type Comparisons
Signals are all digital so they are extremely
good quality and are robust. HDMI also
carries Viera Link control signal and HDCP
digital copyright protection.
The physical connection is also
called HDMI. It is a small simple
to use connector which can fit
through much smaller holes than
a Scart connector
HDMI is used on High definition
products. It carries very high quality
Digital HD video and Digital Audio. It
also incorporates advances switching
technology
Digital (HDMI)
Component video, similar to RGB, offers the
best in picture quality of any of the analogue
connections. The picture is bright clear and
has sharp clear edges.
3 Separate RCA (Phono) leads
are used to connect the playback
device to the TV/Display. Audio
must be connected in addition to
get sound
Similar in principle to RGB, the Red
Green and Blue signals are calculated
within the TV/Display to produce a
high quality video image
Component
RGB offers the best in picture quality of any
of the analogue connections. The picture is
bright clear and has sharp clear edges.
Analogue RGB is usually carried
on a Scart connector along with
stereo audio. A fully wired Scart
connector is necessary to use
RGB
Carries Red Green and Blue signals
that make up a high quality analogue
picture. Audio must be connected in
addition to get sound
RGB (Analogue)
S-Video, also referred to as S-VHS, Y & C or
Chrominance and Luminance, carries better
quality video signals than Composite video.
Black 4 pin S-Video connector or
Scart. If carrying S-Video via
Scart, it should be a fully wired
type.
Carries Video Only as separate Colour
and Black & White Signals
Audio must be connected in addition to
get sound
S-Video
Produces better quality video picture than RF
as the signal does not have to be modulated
Yellow Phono
BNC (Push & Twist)
Scart
Carries Video Only.
Audio must be connected in addition to
get sound
Composite Video
Re-modulating RF from a VCR to a TV for
example adds the stereo soundtrack together
to produce Mono sound. Picture quality also
deteriorates when re-modulating a signal.
RF Connector and Aerial leads
(RF Leads)
Carries both Video and Audio
modulated together to form a
transmittable signal down a single

Understanding Connections
Technology in the audio visual market has moved at an amazing pace over the past few years with big
advancements in all areas.
The result of this is that even the most modest home audio visual can have upwards of 10 cables connecting
devices, something that at first glance looks extremely daunting.
However, there is absolutely nothing complicated about setting up an audio visual configuration providing you
think about it logically and follow a few simple rules. The most simple way to think of connections is as a road
map, and that specific roads need to be followed in order to get to a destination.
Most modern pieces of equipment are connected via Scart leads or HDMI leads. These are multi purpose leads
and very simple to connect to sockets on devices. For example, a simple setup may consist of a video and a
television connected by a Scart socket at each end and linked with a Scart lead.
Scart sockets are usually labelled in a logical fashion. For example, a television with 2 Scart sockets on the back
will usually label them AV1 and AV2. This also applies for videos, DVDs, and most other equipment.
Take this simplified diagram as an example:

The ‘road map’ analogy works well on the above diagram. We want the signal to go from the video to the TV AV2
Socket so..
The signal needs to travel straight down the AV1 to reach it’s destination

The road map thinking also works well on more complicated configurations as is demonstrated in these diagrams

On the above diagram the video signal still needs to follow the same route as nothing has changed there. The
DVD, however is coming from a different location so needs to follow the AV1 from DVD to arrive at the AV1 on
the Television
The road map thinking also works well on more complicated configurations as is demonstrated in these diagrams

Understanding Connections
Continued from page two…
The previous two connection diagrams have involved direct routes from start point to destination. The next
diagram shows a slightly more complicated configuration which involves going via another location before
reaching the final destination.

Sky Box
AV1
Scart Lead
On this configuration we want the signal to come from the sky box end up at the television AV1 socket. However,
because it is useful to be able to record from the sky box it is a better route to go to the television via the video
recorder.
So, in this example, the signal travels from the Sky box via AV1 and arrives at the AV2 on the video recorder. It
then travels from the AV1 on the video to the AV2 of the television in the normal manner.

Understanding Connections
Continued from page three…
The other common type of connection which most people are familiar with is the ‘RF cable’ or ‘Antenna’ cable.
This is the type of cable which has been used for years to carry signals from your house’s roof antenna to videos
and televisions in your front room.
Most audio visual configurations will also need an antenna or ‘RF cable’ to refer to the official term to run right
through their setup in order to carry the signal around the different units. If an RF cable is only plugged into a
video recorder for example, the video recorder will be able to pick up a signal but the television will not because
the cable has not been plugged into the television.
An example of good RF Cabling technique is shown in this diagram. As a rule of thumb, the only devices which
should not include an RF cable in the setup are those which do not have a tuner. For example, a video recorder,
DVD recorder, Sky box, and television should all have an RF cable included in the configuration. However, a
typical DVD player will not as this is purely a playback device.
