	Glossary	Section 8
MPEG	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.
Near Video-On-Demand	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.
Network	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.
NTSC	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.
PAL	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.
PID	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).
Parental lock	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 recordings and 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.
Polarization	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.
Polarizer	A remote controlled device that determines the polarity of the
	signal which is fed to the LNB.
Polarmount	A motorized dish antenna mount which enables a dish to point
	at every ‘visible’ satellite on the Clarke Belt.
Receiver	Unit which takes signals from a dish and converts them so
	they can appear on radio and TV.
RS232 connection	A RS232 connection allows you to connect equipment to the
	receiver which supports the RS232 protocol.
Satellite	A broadcast station, for satellite radio and TV, positioned on		8
	the Clarke Belt.
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.
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.
