Conditional access
A system which is used by service providers to control the
subscriber’s access to certain services, programs and events
like Pay TV.

DiSEqC
A standard through which it is possible to let a DiSEqC
compatible receiver send a signal over the RF cable to a
switching device to switch between different LNBs or dishes.
DiSEqC uses the 22kHz signal to control the switching
device.

EPG
A electronic program guide that comes with a broadcast.
Note that every station fills the EPG differently or not, so
differences in the EPG are not necessarily receiver errors.

FEC
Is an invisible part of a broadcast. that can correct possible
errors in the reception of the satellite signal.

Fixed
A dish antenna that is pointed at one particular satellite.
FTA broadcast
An unscrambled broadcast which you can view without
additional payments to a service provider.

Frequency band
A frequency band is a range of frequencies which are
dedicate to a certain usage. In the satellite area, commonly
known bands are the C-band and the Ku-band.

Horizontal
In the satellite industry, horizontal is used to indicate the
direction in which the received signal is polarized. Normally
you will find that it is abbreviated as H.

PID
MPEG-2 transmits the audio and video information in so-
called packages. Each package has 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).
