Great care is needed to ensure this additional device doesn’t alter the existing network levels, potentially causing inadequate signal levels in
other parts of the installation. For further details, please contact Solutions Group.
Fibre systems
Most fibre optic systems stack all of the channels into one very large group, negating the need to have voltage or tone signalling. The fibre
optic receivers located close to the STB
then convert this large band of channels back into a form the set top box can work with. Presently
these receivers recreate a 4 band system, mimicking an LNB. Some will also recreate a terrestrial output. To upgrade these systems for Sky
Q, the user interface must be replaced with a new two output wideband device for Sky Q. Some versions will be able to recreate the terrestrial
feed as well.
Hotel Systems (SMATV)
The main difference between an IRS system and a hotel system is the way channels are delivered. IRS systems rely on a STB being located
next to a TV and all control is determined by the STB. In a SMATV or similar head-end system, the channels are preset at the head end using
multiple STBs set to one channel only. The viewer then selects th
e channel from the TV. All available channels are delivered simultaneously
at TV frequencies and the TV is tuned in as required. As a result, Sky Q is probably unnecessary for SMATV systems.
Existing systems
There are around 15 million traditional Sky set top boxes in use today, around two thirds on subscription. Of these around 10% are on
communal systems and will continue to operate without a problem for the foreseeable future. The Sky Q systems will be initially be charged
at a premium and many viewers will continue with their existing STBs. Presently the wideband-ready products are quite expensive and only
premium installs are likely to take up this new offering. Traditional systems will need to be maintained and over time, some
will need to be upgraded. Communal systems will probably use a hybrid approach, offerin
g traditional feeds for most consumers, plus a
spliced-on upgrade for those that demand it on a case by case basis.
