Digital services are in great demand. Already, some 11 million households have acquired digital reception equipment. The Government will progressively switch off analogue broadcast services in different parts of the country from 2005 through to 2010. Households which do not already have access to digital services must be upgraded before analogue services cease.

Digital Switchover in Birmingham, West Midlands

To be prepared for the digital switchover in Birmingham and the West Midlands, call RF Digital Aerial Installers for a digital satellite installation. today.

Existing communal aerial systems must be upgraded, to satisfy residents’ demands for access to digital services and to meet the governments target for digital switch over. IRS is the only communal aerial system that can meet the demand for access to the full range of digital services. It delivers everything to everyone and gives households connected to the system freedom to choose the services that best meets their requirements.

Digital Satellite Installation System Types

There are several ways of distributing TV signals in buildings with multiple receivers.

MATV – Master Antenna TV System
For more than 50 years communal aerial systems have been designed using a configuration known as “tree and Branch” and a variant known as “loop”In these systems, signals are received via a shared antenna, amplified by a head end amplifier and distributed through a distribution cable to sub-feeds connected to each system outlet. ”Loop” systems are similar in design except that cables are looped through the outlets. Screening levels in older communal systems are often insufficient for consistently reliable reception of digital services.	Tree & Branch System
SMATV – Satellite Master Antenna TV System
As MATV, but includes satellite signals from central satellite head end.
IRS – Integrated Reception Systems
IRS uses a system configuration known as “star-wire”; co-axial sub-feeds run from each system outlet to one or more common locations, creating a direct connection between each outlet and the system electronics. For larger sites, a cabled backbone is used to extend the star wire configuration. Star-wired systems have fewer connections between each outlet and the system electronics than other system configurations and are typically more reliable and easier to maintain than systems built to older designs.
