Glossary

Bitstream

Digital multi channel audio data (e.g. 5.1 channel) before decoding to the individual

channels.

Decoder (e.g. DTS / Dolby Digital)

A decoder converts the coded audio signals of the DVDs back to the original signals.

This procedure is called decoding.

DPOF (Digital Print Order Format)

DPOF is the standard format for printing pictures recorded with a digital camera etc.

It enables automatic printing in a photo shop or on your own printer.

LPCM (Linear PCM)

These are uncompressed digital signals, similar to those on CDs. LPCM sound can be

used during recording in XP mode.

PCM (Pulse Code Modulation)

Scan frequency

When converting (encoding) to a digital signal, the (analogue) sound signal is scanned

at certain time intervals. The number of scans per second is called the scan frequency.

The higher the scan frequency, the better the original sound is reproduced.

Sound mixing

This is the remixing of the multi channel sound that exists on some discs to two channels for

stereo output. Sound mixing makes sence e.g. if you want to playback the 5.1 channel

sound of a DVD over your television speakers. However, some discs do not allow mixing.

In this case, only the two front channels are output.

Brightness signal Y

Analogue video signal showing the brightness levels of the picture, regardless of the colour

signal (C) chrominance signal. It allows for higher resolution and colour reproduction true

to the original colour.

Chrominance signal

The three signals red, green and blue can be converted into three other signals: luminance

Y (luminance signal) and 2 chrominance signals P /P (colour difference signals).

Digital audio optical fibre cable

When this cable is connected, the electronic signals for output to the amplifier are

converted into optical signals.

Standard procedure for recording uncompressed digital audio signals.

RGB (Red Green Blue)

This refers to the three primary colours of light, red (R), green (G), and blue (B) and also

the method of producing video that uses them. By dividing the video signal into the three

colours for transmission, noise is reduced for even higher quality images.

TIFF (Tag Image File Format)

This is a system used for compressing/decoding colour still pictures, a common format for

storing high quality images on digital cameras and other devices.
