There are many different connections and
transmission formats available to the home entertainment enthusiast.
Deciphering which format is correct for your needs is not
always easy. The following should help you make that choice.
VIDEO FORMATS - DIGITAL
HDMI
High Definition Multimedia Interface (HDMI) is a unique technology
that supports uncompressed digital mutlichannel audio and
true high definition video signals. HDMI can be found on most
LCD and Plasma screens as well as many high quality DVD players
and Satellite receivers. HDMI is physically a small cable,
typically 5mm in diameter with a 29-pin plug that measures
only 21mm wide by 5mm high.

DVI
Digital Video Interface (DVI) delivers digital video signals
only by the use of extensive bandwidth. That's why the picture
quality is true high definition. DVI is backwards compatible
with HDMI for transferring digital video signals but does
not include sound.

VIDEO FORMATS - ANALOGUE
COMPONENT
VIDEO
Best of all analogue picture connectors, it separates images
into their colour components. Component Video or YUV is the
highest possible analogue video standard to transfer signals
in almost High Definition quality between LCD/Plasma/Projector
TV and DVD player. The video signal is transferred over 3
separate conductors: Green (Y), Blue (Pb or Cb) and Red (Pr
or Cr) and therefore offers superior video transfer over Composite
or S-Video formats. The separation of the picture components
into individual cables dramatically increases picture resolution
and detail, making Component ideal to use with widescreen,
LCD & plasma televisions.

SCART
Carries pictures and analogue sound from system to screen.
RGB Scart gives the best pictures over regular scart leads.
Scart technology offers the most complete & convenient
connection between home entertainment components. Scart to
scart cables carry video, stereo audio and command signals
for menu facilities on even the most advanced televisions.
Scart is capable of transmitting and receiving all video formats,
including component & RGB, so the highest quality picture
transfer is possible.

S-VIDEO
Carries pictures only. Better than composite video and regular
Scart, but not as good as RGB Scart or Component Video. By
electronically separating the video signal into two paths
the S-Video format provides an improved picture transfer over
single core composite cable designs. In splitting colour (chrominance)
and brightness (luminance) signals, the risk of interference
between the two is greatly reduced. Picture quality is greatly
improved and there is a reduction in colour bleeding.

COMPOSITE
VIDEO
Average-quality cable for carrying pictures from system to
screen. Composite video cable carries the picture signal only
and leaves the audio signal to be carried by another cable,
whereas standard UHF coaxial cable combines both video and
audio signals. Composite delivers greater bandwidth than UHF
Coaxial cable and therefore gives you better picture quality
by separating the audio and video signals.

RGB
+ SYNC
All video signals require synchronisation
of both the horizontal and vertical picture information. Combined
synchronisation, or 'CS' as it is also known, provides both
horizontal sync and vertical sync in a single conductor. By
keeping sync separate from quality picture information provided
by the Component Video format, accurate colour and timing
transfer is achieved.

VGA
VGA interconnects are designed for transferring high resolution
analogue video signals from Media Centres, DVD Players and
PC's to your LCD/Plasma monitors.

ANALOGUE AUDIO
One of the most common transmission formats, audio analogue
is used to transfer stereo audio signals only. Hugely versatile,
the audio analogue interconnect can range from the most affordable
entry level to the highest possible quality available, depending
on the materials and the geometry used in cables construction.

DIGITAL
AUDIO
Carries digital 5.1 sound from a DVD player or a SKY + Box
to a amplifier. Digital audio signals are both complex and
fragile. There are two ways of transmitting the signal, one
is a 75 Ohm coaxial cable and the other is optical transmission.
75 Ohm coaxial cables are able to transmit digital signals
by restricting the impedance to 75 Ohms using precise construction
and materials. Optical cables work by transmitting light signals
down medical grade light conductive cores.

UHF
UHF coaxial cables combine both video and audio signals in
one compact design. True 75 Ohm construction, required by
the transmission format, will ensure a consistent and high
standard of signal reproduction. UHF signal cables can also
be used to transmit FM stereo signals from a wall socket to
your tuner.

CONNECTION TYPES
1 RCA (PHONO)
The female RCA socket is designed to accept a male coaxial
connector. The connector can carry both analogue and digital
stereo audio and video signals.
2
SCART
The female Scart socket is
designed to accept male 21 pin scart connector. The 21 pins
can transfer each of the signal types mentioned above including
menu command signals for televisions and DVD players.
3
MINI TOSLINK
Mini TosLink was designed for
portable applications such as personal CD and MD players,
where space was too tight for the TosLink connector.
4
TOSLINK
The female TosLink socket is designed to accept the male
TosLink connector, protecting the connection from any light
interfering with the delicate signal.
5
BNC
The female BNC socket sits proud of the equipment, and is
designed to accept a male coaxial BNC connector. The BNC
connector is often used for high quality RGB + Sync video
transmission because of the excellent connection integrity
achieved when the male plug is twisted onto the female socket.
6
UHF
The female UHF socket is designed to accept the male UHF
connector for the transmission of the television of FM broadcast
signal.
7
S-VIDEO
The female S-Video socket is designed to accept a male 4
pin s-video connector. The 4 pins carry the separated chrominance
and luminance signals to and from the video source component.
8
F CONNECTOR
The female F Type socket is
designed to accept the male screw on F connector. Used for
carrying television broadcast signals where audio and video
are combined, typically to connect your TV or Video to your
cable TV, satellite or roof antenna.
