Others Before you start Connections Getting started Recording Disc Playback Analog audio An electrical signal that directly represents sound. In contrast, digital audio can be an electrical signal, but is an indirect representation of sound. See also Digital audio. Aspect ratio The width of a TV screen relative to its height. Conventional TVs are 4:3 (in other words, the screen is almost square); widescreen models are 16:9 (the screen is almost twice as wide as it is high). Chapter Just as a book is split up into several chapters, a title on a DVD disc is usually divided into chapters. See also Title. Component video output This is a video signal format that conveys each of three principal colors of light (red, blue and green) through different signal lines.This allows the viewers to experience picture colors as original as it is.There are several signal formats, including Y/PB/PR and Y/CB/CR. CPRM (Content Protection for Recordable Media) This is a format used to record copy-once programs. By recording coded data on the area of DVD discs that ordinary writing software cannot write on, it prevents copy-once programs from being recorded repeatedly on different media. Digital audio An indirect representation of sound by numbers. During recording, the sound is measured at discrete intervals (44, 100 times a second for CD audio) by an analog-to-digital converter, generating a stream of numbers. On playback, a digital-to-analog converter generates an analog signal based on these numbers. See also Sampling frequency and Analog audio. Glossary Dolby Digital The system developed by Dolby Laboratories to compress digital sound. It offers you sound of stereo(2ch) or multi-channel audio (up to 5.1ch). DTS (Digital Theater System) DTS is a 5.1 channel surround sound system, but it is different from Dolby Digital.The formats were developed by Digital Theater System, Inc. Finalize To make recorded contents on DVD discs possible to be played back on DVD players.With this unit, it is possible to finalize DVD-RW/DVD-R discs. MP3 (MPEG Audio Layer 3) MP3 is a method of compressing files.You can copy MP3 files on CD-RW/-R discs from the computer and play back the files on this unit. PCM (Pulse Code Modulation) PCM is a format that converts audio into digital data. It is mainly used for Audio CDs and DAT.This unit can play back sounds as realistic as possible by converting even compressed Dolby Digital and MPEG audio to PCM. Playlist From this list you can play back contents of a disc in your desired order or sequence. Also it allows to search a specific scene directly. Progressive scan (480p) A type of display that does not split each frame into fields, and instead scans directly through all the scanlines of each frame in order. Progressive scan provides less flickering and higher image resolution than traditional (480i) TV signals. Refer to page 14 for instructions on selective progressive scan mode. Regions code Regions associate discs and players with particular areas of the world.This unit will only play back discs that have compatible region codes.You can find the region code of your unit by looking at the rear panel. Some discs are compatible with more than one region (or all regions). Sampling frequency The rate which sound is measured by a specified interval to turn it into digital audio data.The numbers of sampling in one second defines as sampling frequency.The higher the rate, the better the sound quality is. SAP (Secondary Audio Program) Sub-audio channel which is delivered separately from main-audio channel.This audio channel is used as an alternate in bilingual broadcasting. S-Video output It delivers independently each signal of color(C) and luminance(Y) to TV as video signals, so that higher-quality picture will be materialized. Title (DVD only) A collection of chapters on DVD disc. See also Chapter. Track Audio CDs use tracks to divide the content of a disc.The DVD equivalent is called a chapter.
