MATV

 

A multitude of commercial premises including hotels, offices,

housing developments and holiday parks, now utilise some form

of structured cable system to supply an array of different

programmes and information services to their end-user customers.

 

These modern 'Multi point' distribution systems normally incorporate

a form of MATV system (Master Antenna Television), which is

dependent upon the client's specific needs. While MATV systems

may vary in size and complexity, the basic structure of the system

includes two clear areas of interest;-

 

1.The Head End System The MATV Head End is primarily

tailored to provide the end-user with 'Off-Air' terrestrial services

like BBC1, BBC2, ITV, C4 and C5. The 'Off-Air' services are

initially received by a robust high gain aerial installation, which is

mounted at a convenient position on the premises. A high quality

and Mast Head Amplification ensure that signal quality is optimised

at the front end of the Head-End system therefore minimising any

form of inherent noise, prior to the main amplification stages. This

signal feed is then passed through channel equalisation stages to

balance all incoming channels before additional filtering stages are used

to minimise or reject unwanted interference sources. Clients now have

the option of inserting additional UHF/ VHF channels for special

features like information services (Guest Information), Video programmes

(PPV) or 'Off Air' radio services (Radio1 etc), before the signal is then

fed to the main launch amplification for onward distribution.

 

2. The Distribution System The output signal from the launch amplifier

is now inserted into a structured cabling system constructed of high

grade cable and screened outlet plates, which are installed within the

premises to provide the end user with the required service package.

Structured cabling systems can vary greatly in size, dependent upon

the physical layout of the premises they are being installed into and the

number of outlet points required to support the end-users customer requirements.
