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). Scrambled 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 entered
to unlock the unit to allow access to certain functions and channels.
Programme package
The channel package for a digital transponder normally includes several TV and radio channels. Each
channel package has a fi xed assignment for the transponder transmission frequency, for polarisation
(horizontal or vertical), for the symbol rate and for the Viterbi rate or error rate.
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
Receiver
RGB
Video signal made up of three individual colour signals (red, green, blue)
SAT IF signal
Receiver input signal
Scart cable
