SMATV stands for Satellite Master Antenna Television and refers to a system that uses multiple satellite and broadcast signals to create a single integrated cable signal for distribution to a cabling network. In other words, with an SMATV system, you can become your own in-house cable company.
The purpose of SMATV is for supplying and controlling the number and type of channels to multiple televisions, not only TV channels but FM channels as well. It provides Reception of DBS ( Direct Broadcast Satellite ) TV/FM channels for hotels, schools, prisons, hospitals and commercial properties with multiple tenants. Using a master antenna system, video signals, audio signals and decoder signals can also be distributed.
A SMATV headend is used to receive and rebroadcast Satellite TV channels throughout a property from a single satellite feed.
How SMATV does it Work & Its Infrastructure ?
There is a single satellite dish and TV antennae which receives the program from satellite and local broadcast network. The signals are then fed into several racks of electronic reception equipment which tune in the channels you choose for your channel line-up and combine them into a single cable signal . Again these feed can include local feed of in-house channels like Campus TV Station and Local Information Channel of a large gated community.
All systems by Satcom Networks are installed in accordance with Confederation of Aerial Industries (CAI) standards.
MATV is the short form of Master Antenna Television. Using this technology, many apartments, hotels, schools and other multi-unit buildings can distribute TV and FM signals to a number of receivers. In order to accomplish this without a loss of signal quality, these systems must be carefully planned and engineered through the effective use of MATV equipment and techniques.
An MATV system is basically a network of cables and specially designed components that process and amplify TV and FM signals and distribute them from one central location to the many receiver points connected to the system. Consider the situation in which there is a tall apartment tower having 100 flats and therefore 100+ TV sets. Now it would be extremely expensive to install and maintain l00 separate antennas, one for each flat. This not only gives an ugly and cluttered look of the external facade but also cause interference problems to each other.
A modern MATV system can carry digital television signals through an aerial, both free-to-view and subscription, FM radio and DAB (Digital Audio Broadcasting) but it cannot carry satellite signals.
How MATV Works?
MATV consists of one aerial which is a conventional UHF TV aerial which receives digital signals .These signals are then processed in the system and delivered through the distribution network to a socket outlet on every home. From this socket we can connect a TV set and watch our favourite channels among the channels delivered to us.
