Digital Satellite Services
This IRD has been designed to receive and process
digital satellite signals from satellites such as Astra
and Eutelsat. The satellites act as mirrors in the
transmission process, beaming the Service
Provider's signals back to your satellite dish.
Compared to conventional TV (analogue), digital
technology typically presents higher quality
pictures, sound comparable to CD quality, and
many more services.
Satellite technology also enables excellent reception
of satellite TV services even in remote rural areas
where good quality terrestrial reception has never
before been possible.
The term "Services" is used instead of "Channels"
because digital compressed TV and audio technolo-
gy uses the available bandwidth much more effi-
ciently, and several services can use the bandwidth
of one channel.
The signals from the satellite contain data in addi-
tion to the digital TV and audio signals. The IRD
extracts, processes and stores this information.
This provides, for instance, up to date text informa-
tion on the content and status of the various servi-
ces at the touch of a button. Convenient facilities
are also provided to manipulate received data in
order to customise viewing and listening prefer-
ences.
Many more features that are possible due to the
nature of compressed digital TV will become availa-
ble in the near future.
Conditional Access
Most digital satellite TV and audio services are only
available on a subscription basis and can only be
enjoyed via the conditional access components.
These are the Conditional Access Module and the
Smart Card.
❒
Conditional Access Module (CAM)
The CA Module provides the crucial conditional
access technology required to decode the scram-
bled signals from the Service Provider. The modu-
lar approach ensures that the cost of possible futu-
re upgrades will be greatly reduced and that the
IRD will keep in step with the latest advances in
conditional access technology.
The IRD is supplied with the CA Module inserted
into its slot in the rear panel.
❒
Smart Card
You should have purchased a Smart Card from the
dealer when you purchased the IRD. The Smart
Card looks similar to a credit card and is inserted
into the slot behind the right-hand front flap of the
IRD.
A valid Smart Card entitles you to view and listen to
all the services you choose to subscribe to. Full
details of subscription options are supplied with the
card.
Your Personal Identification Number (PIN) and
subscription details are stored in the Smart Card.
