2. The Marketplace
Currently around 5.5 million homes connected to a communal satellite system.
Requirement is therefore for :
Sky Q requires connection for more than one tuner. In normal circumstances each tuner would require a cable. Sky Q only requires a single cable
Freesat likely t o follow Sky Q protocols

3. What is a Sky Q Set Top Box?
New Set Top Box (Sky Q) is the latest Sky offering
Provides up to 4 channels recording whilst watching a 5th
Streams to up to 3 mini-boxes and 2 other handheld devices. – will be able to do up to 12 individual channels
Sky Q Silver is main box but Sky Q base model works in a Similar way with less features
Sky Q is 4K ready – Ultra High Definition
Broadband re transmitter

5. Sky Q Sky Handset works on Bluetooth as well as Infrared
First new design in nearly 20 years

6. Changes to the way a Sky Set To Box works
New Set Top Box (Sky Q) works in a different way :
Domestic installs still require 2 cables but now what’s on them is different.
Wideband LNB used for inputs to Sky Q - 1 x Vertical and 1 x Horizontal – LNB’s cover the whole of the Band – no longer switched between Upper and Lower Bands
Communal satellite systems (IRS) need major changes and the Electronics are different.
This is because of extended frequency ranges within the Sky Q tuning system 290MHz. To 2350MHz.

7. Communal Aerial Systems IRS
dSCR Multiswitch
Requirement now for dSCR enabled multi-switches – utilises just a single cable for all the requirements up to 16 User Bands – Theoretically 32 User Bands.
Larger number of tuners being connected on to a communal satellite system – all via a single cable to each dwelling
Makes the installation simple and tidy with no additional cabling required from the common areas – easily upgraded

The ASTRA Satellite System transmits signals in the frequency range between GHz and GHz (the Ku band). The full band is divided into Low band ( GHz) and High band ( GHz).
To double the number of services that can be transmitted across the whole frequency range the ASTRA satellites transmit signals polarised horizontally and vertically. The polarisation technique involves transmitting two separate electromagnetic waves with their electric fields at 90º to each other.
Dividing the frequency range in this way, with two polarities in both Low and High band, creates four ‘sub-bands’ with a frequency range of around 1 GHz each:
Vertical Low band.
Horizontal Low band.
Vertical high band.
Horizontal High band.
