78BitstreamDigital multi-channel audio data (e.g. 5.1-channel) before decoding to the individualchannels.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.Digital audio optical fibre cableWhen this cable is connected, the electronic signals for output to the amplifier areconverted into optical signals.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.Chrominance signalThe three signals red, green and blue can be converted into three other signals: luminanceY (luminance signal) and 2 chrominance signals P /P (colour difference signals).B RBrightness signal YAnalogue video signal showing the brightness levels of the picture, regardless of thecolour signal (C) chrominance signal. It allows for higher resolution and colour reproductiontrue to the original colour.LPCM (Linear PCM)These are uncompressed digital signals, similar to those on CDs. LPCM sound can beused during recording in XP mode.PCM (Pulse Code Modulation)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 alsothe method of producing video that uses them. By dividing the video signal into the threecolours for transmission, noise is reduced for even higher quality images.Scan frequencyWhen converting (encoding) to a digital signal, the (analogue) sound signal is scannedat 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 mixingThis is the remixing of the multi-channel sound that exists on some discs to two channelsfor stereo output. Sound mixing makes sence e.g. if you want to playback the 5.1-channelsound of a DVD over your television speakers. However, some discs do not allow mixing.In this case, only the two front channels are output.TIFF (Tag Image File Format)This is a system used for compressing/decoding colour still pictures, a common format forstoring high quality images on digital cameras and other devices.Informations Glossary
