Digital Satellite Receiver
A frequency range (10.70-18.00 GHz) used by most
European TV satellites.
A device behind the feedhorn which processes the signal
into a format which is understood by the receiver for further
processing
A LNB with an integrated Feedhorn. So the LNBF comes as
one single unit.
The Moving Picture Experts group is founded by the ISO to
provide a basis for the coding and compression of moving
pictures. MPEG has now become a standard method for the
digital transmission of video and sound using less bandwidth
than the analog transmission method.
Multi channel system broadcasting many copies of a film
with staggered start times so a complete film is always
available to a viewer with a short waiting period.
With respect to the receiver, a network (also known as a
bouquet) is a set of programs that is offered by a single
service provider.
USA video standard with image format 4:3, 625 lines, 60 Hz
and 4 MHz bandwidth with a total of 6 MHz video channel
width.
European video standard with image format 4:3, 625 lines,
50 Hz and 4 MHz bandwidth with a total of 8 MHz video
channel width.
MPEG-2 transmits the audio and video information in so-
called packages. At the beginning of each package is an
identifier (PID) present which tells the receiver what to do
with the received information. Satellite receivers use
normally four types of PID, these are VPID (video PID), APID
(audio PID), Program Clock Reference (PCR PID) and data
PID (EPG information).
A feature which is introduced to give you the possibility to
'lock' or 'hide' several functions of the receiver to prevent
unauthorized persons (children) to view broadcasts that are
not suitable for them. The use of the parental lock requires a
PIN code. With this PIN code you can change or unlock the
locked or hided channels.
With this feature, the viewer has to pay a certain price per
month (or other period) to receive all programs of a certain
channel.
Conditional access service where the user is able to buy one
particular program from a particular service provider.
With Pay TV, the consumer has to pay for certain programs
or services.
The PIN code or Personal Identification Number is
necessary to make use of the parental lock feature. The PIN
code has four digits which can be set personally.
Broadcasts are done in a particular frequency band. To make
maximum use of a frequency band and bring you the
maximum number of programs, the broadcasts are polarized
in different ways to fit as many as possible programs into one
frequency band.
A remote controlled device that determines the polarity of the
signal which is fed to the LNB.
A motorized dish antenna mount which enables a dish to
point at every 'visible' satellite on the Clarke Belt.
