As opposed to the digital processing method which only knows two states ( 1 or 0, on or off ), analogue
processes consist of a multitude of values at any range of infinitely variable steps. This multiplicity is
faced by the limited range of possibilities of storing and reproducing the relevant information.
Multiple-channel digital audio data prior to its decoding and assignment to the different channels.
Analogue video signal which carries the picture's luminance levels ( Y signal or luminance signal )
independent of the chrominance signal ( C ). The result is an improved resolution and higher colour
fidelity. This quality can be deployed only if the entire pathway of the signal is Y/C-separated.
The three signals red, green and blue can be converted into three different signals: luminance signal Y
( luminous density ) and two chrominance signals P /P or C /C ( colour difference signals ).
Digitising is a reduction of analogue states. However, due to their limits of perception human individuals
will not notice the reduction and therefore experience hardly any or no restrictions. The benefit of
digitisation is that digital data can be reproduced in any way but without any loss.
Method of encoding digital signals, developed by Dolby Laboratories. The signals can be either
conventional ( 2-channel ) stereo signals or 5.1-channel audio signals. The signals are very much
compressed in the process to enable recordings of large volumes of data.
Sound system used in cinemas or movie theaters all over the world. The system is marked by high-
quality sound separation. ( 2-channel or 5.1-channel playback ).
MP3 or MPEG 1 Audio Layer 3 is a file compression format used for digital audio files.
It provides files of an extremely small size and may cause a consequential loss of quality.
If you connect the player with this cable, the electronic signals will be converted into optical signals
before being output to the amplifier. This method reduces the noise produced by the electronic circuitry.
Red Green Blue: The RGB values allow you to define a hue.
The actual colour results from the intensity of red, green and blue portions of every pixel.
WMA ( Windows Media Audio ) is a file compression format developed by Microsoft. It achieves the
same sound quality as MP3 with a file size that is smaller than that of MP3.
