MUX (Multiplex)

In analogue television broadcasting a transmission channel (e.g. UHF 
channel 42) has only one TV channel (program) or service. In digital 
terrestrial television broadcasting, a transmission channel (e.g. UHF 
channel 42) is divided into different sections that can have more than 
one TV channel (program) or service. Such a transmission channel 
used for digital terrestrial broadcasts is called a MUX.

NTSC

USA video standard with image format 4:3, 525 lines, 60Hz and 4MHz 
bandwidth with a total of 6MHz video channel width.

PAL

European video standard with image format 4:3, 625 lines, 50Hz and 
4MHz bandwidth with a total of 8MHz video channel width.

PID

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.

QAM

Quadrature Amplitude Modulation is a technique where the signal is 
polarized and modulated in order to get more TV or Radio channels into 
a physical VHF or UHF channel.

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 colour 
(chrominance).

Transmission mode

The COFDM technology spreads the data between many carrier waves. 
The 2k mode has 1705 carriers for higher interference environments 
and the 8k mode has 6817 carriers for lower interference environments.

UHF-band

Parts of this band (471MHz-860MHz) are dedicated for TV and Radio 
broadcasting.

VHF-band

Parts of this band (171-470MHz) are dedicated for TV and Radio 
broadcasting.
