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.

PID
(Video, Audio, PCR)
A digital signal is divided into so called packages (as suit cases on a
transport belt). Each packet holds certain information for Video, Audio,
timing and completeness of the packet stream so that the receiver can
compose a distortion free signal for your TV or Radio.

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.

RGB
RGB is used to transfer a TV signal in DVD quality. The quality is
superior to SVHS and CVBS.

RS-232 connection
A RS-232 connection allows you to connect equipment to the receiver
which supports the RS-232 protocol.

SCART cable
A SCART cable is also known as ‘Peritel’ cable and is commonly used in
Europe to connect the audio and video equipment. A fully furnished
SCART cable has 21 wires which is at both sides finished with a 21-pin
connector.

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.

Vertical
In the satellite industry, Vertical is used to indicate the direction in which
the received signal is polarized. Normally abbreviated as V.
