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).
Parental control
A feature which is introduced to give you the possibility to ‘Lock’ 
several functions of the receiver to prevent unauthorized persons 
(children) to view broadcasts that are not suitable for them. The 
use of the Parental control requires a PIN-code. With this PIN-
code you can change or unlock the locked channels.
Pay-Per-Channel
With this feature, the viewer has to pay a certain price per month 
(or other period) to receive all programs of a certain channel.
Pay-Per-View
Conditional access service where the user is able to buy one 
particular program from a particular service provider.
Pay TV
With Pay TV, the consumer has to pay for certain programs or 
services.
PIN-code
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.
Polarity
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 much as possible programs into one frequency band.
Receiver
Unit which takes signals from a dish and converts them so they 
can appear on radio and TV.
RGB
RGB is used to transfer a TV signal in DVD quality. The quality is 
superior to SVHS and CVBS.
SAT
With respect to the receiver, a satellite is a broadcast station, for 
satellite radio and TV, positioned on the Clarke Belt.
SECAM
SECAM (Systeme Electronic Pour Couleur Avec Memoire) is 
almost the same as PAL. It is used in France, Russia, and parts of 
Africa and Eastern Europe.
Service provider
A service provider is a company or organization that collects and 
offers you a number of programs and services. Some are free of 
charge and others you have to pay for.
Smartcard
A card that contains a ‘smart’ code and is used to de-scramble 
encrypted broadcasts when placed in a decoder or receiver with a 
built-in decoder.
Stream
The signal which is received from the transponder which contains 
the together with the video signal, additional information that the 
receiver needs in order to process the received signal correctly.
SVHS
SVHS means Super-VHS and is superior to a CVBS signal but 
less then a RGB signal. Normally it is a single cable consisting of 
four wires because the black/white (luminance) is separated from 
the color (chrominance).
Symbol rate
Invisible information which tells the receiver at which speed (rate) 
the transponder sends the digital information (symbols). The 
receiver must be able to handle the Symbol rate to process the 
signal correctly into a correct image.
TP 
Equipment inside a satellite responsible for receiving a single 
uplinked channel and rebroadcasting it back to Earth.
Vertical
In the satellite industry, Vertical is used to indicate the direction in 
which the received signal is polarized. Normally you will find that it 
is abbreviated as V.
