Short Technical Guide

HD – Ready

This is a label created by the EICTA

(European Information, Communications and

Consumer Electronics Industry Technology

Association) for equipment that is capable of

reproducing HDTV.

HDCP – High-bandwidth Digital Content

Protection

Encryption system which protects the HDMI

and DVI interfaces for secure transmission of

video and audio data. HDCP should be used in

Europe for HDTV standard transmissions.

HDMI - High Deﬁ nition Multimedia Interface

Digital interface for digital video and audio

data transmission (preferred for HDTV).

HDTV – High Deﬁ nition Television

High resolution television with a resolution up to

5 times higher or ﬁ ner than PAL or NTSC.

High band

Satellite frequency range between 11.7 GHz and

12.75 GHz.

H.264

Another designation for MPEG-4/AVC.

LNB - Low Noise Block Converter

Converts the satellite downlink frequencies into

the Sat-IF for the ﬁ rst satellite.

Low band

Satellite frequency range between 10.7 GHz and

11.7 GHz.

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 become established 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. mainmenu)

PAL

Analogue TV standard

Pay TV

Television channels available on subscription

(e.g. Sky). Encrypted transmitters which can

only be decrypted 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

synchronization 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.

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.

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 that is used for

satellite transmission (8PSK is also used in

connection with HDTV).
