MPEG-2
MPEG is the abbreviation for Moving Picture Experts Group, a working group that formulates internationally
applicable standards for the digital compression of video and audio. MPEG-2 has established itself as the
standard for compression of digital TV signals. MPEG-2 works up to a data rate of 100 Mbit/s.
MPEG-4
A further development of MPEG-2 with even higher data compression, intended for HDTV transmissions.
NID
The channel identifi cation number is also referred to as the Network ID or NID.
OSD – On-Screen Display
Displays by the receiver on the TV screen (e.g. main menu)
PAL
Analogue TV standard
Pay TV
Television channels available on subscription (e.g. PREMIERE). Encrypted transmitters which can be
decrypted only by using the appropriate smart card. As a rule these services are subscription-only.
PCMCIA
Standard for internal decoder interface for pay TV
PID
The PID (Packet IDentifi cation) number is an identifi cation number for video signals and audio signals in
the digital data stream of DVB-MPEG -2 signals. The receiver uses the PID number to create a unique
assignment for the video and audio data transmission. The PCR PID is the identifi cation number for the
synchronisation signal. The PID PCR is normally identical to the video PID. For programmes broadcast
in multiple languages, the audio PD can be entered manually to assign a different language to the TV
programme. After the PID is entered, the digital receiver automatically selects the audio data identifi ed by
the PID number from the data stream and assigns it to the video signal.
PIN
Personal Identifi cation Number. For this unit the PIN is a 4-digit numeric code which must be input to
unblock the unit to allow access to certain functions and channels.
QAM – Quadrature-Amplitude-Modulation
Digital modulation process with phase shift keying, which is used for transmissions in cable networks.
QPSK – Quadrature Phase Shift Keying
Digital modulation process used for satellite transmission. (8PSK is also used in connection with HDTV)
Receiver
Satellite receiver
RGB
Video signal made up of three individual colour signals (red, green, blue)
