72RQT9118BitstreamThis is a signal compressed and converted into digital form. It isconverted back to a multi-channel audio signal, e.g., 5.1-channel, bya decoder.CPRM (Content Protection for Recordable Media)CPRM is technology used to protect broadcasts that are allowed tobe recorded only once. Such broadcasts can be recorded only withCPRM-compatible recorders and discs.DecoderA decoder restores the coded audio signals on DVDs to normal. Thisis called decoding.Deep ColourThis unit incorporates HDMITM (V.1.3 with Deep Colour) technologythat can reproduce greater colour gradation (4096 steps) whenconnected to a compatible TV.You can enjoy exceptionally rich, natural-looking colours, withsmooth, detailed gradation and minimal colour banding.[A lower colour gradation (256 steps), without deep colour, will bereproduced if connected to a TV which does not support deep colour.The unit will automatically set appropriate output to suit theconnected TV.]Dolby DigitalThis is a method of coding digital signals developed by DolbyLaboratories. Apart from stereo (2-channel) audio, these signals canalso be multi-channel audio. A large amount of audio information canbe recorded on one disc using this method.When recording on this unit Dolby Digital (2 channel) is the defaultaudio.Down-mixingThis is the process of remixing the multi-channel audio found onsome discs into two channels. It is useful when you want to listen tothe 5.1-channel audio recorded on DVDs through your TV’s speakers.Some discs prohibit down-mixing. If this is the case, this unit can onlyoutput the front two channels.DTS (Digital Theater Systems)This surround system is used in many movie theaters. There is goodseparation between the channels, so realistic sound effects arepossible.Dynamic rangeDynamic range is the difference between the lowest level of soundthat can be heard above the noise of the equipment and the highestlevel of sound before distortion occurs. Dynamic range compressionmeans reducing the gap between the loudest and softest sounds.This means you can hear dialogue clearly at low volume.Film and VideoDVD-Videos are recorded using either film or video. The unit candetermine which type has been used, then uses the most suitablemethod of progressive output.Film: Recorded at 25 frames per second (PAL discs) or 24 framesper second (NTSC discs). (NTSC discs recorded at 30 framesper second as well.)Generally appropriate for motion picture films.Video: Recorded at 25 frames/50 fields per second (PAL discs)or 30 frames/60 fields per second (NTSC discs). Generallyappropriate for TV drama programmes or animation.FinaliseA process that makes play of a recorded CD-R, CD-RW, DVD-R, etc.possible on equipment that can play such media. You can finaliseDVD-R, DVD-R DL, DVD-RW (DVD-Video format), +R, and +R DL onthe unit. After finalising, the disc becomes play-only and you can nolonger record or edit. However, finalised DVD-RW can be formattedto become recordable.FormattingFormatting is the process of making media such as DVD-RAMrecordable on recording equipment.You can format DVD-RAM, DVD-RW (only as DVD-Video format) and+RW or unused +R and +R DL on this unit.Formatting irrevocably erases all contents.Frame and FieldFrame refers to the single images that constitute the video you seeon your TV. Each frame consists of 2 fields.= +Frame Field FieldA frame still shows 2 fields, so there may be some blurring betweenthem, but picture quality is generally better.A field still shows less picture information so it may be rougher, butthere is no blurring.HDMI (High-Definition Multimedia Interface)Unlike conventional connections, it transmits uncompressed digitalvideo and audio signals on a single cable. This unit supports high-definition video output [720p (750p), 1080i (1125i), and 1080p(1125p)] from HDMI AV OUT terminal. To enjoy high-definition videoa high definition compatible television is required.JPEG (Joint Photographic Experts Group)This is a system used for compressing/decoding colour still pictures.If you select JPEG as the storage system on digital cameras, etc.,the data will be compressed to 1/10-1/100 of its original size. Thebenefit of JPEG is less deterioration in picture quality considering thedegree of compression.LPCM (Linear PCM)These are uncompressed digital signals, similar to those found onCDs.MPEG2 (Moving Picture Experts Group)A standard for efficiently compressing and expanding colour video.MPEG2 is a compression standard used for DVD and satellite baseddigital broadcasting. This unit records programmes using MPEG2.MP3 (MPEG Audio Layer 3)An audio compression method that compresses audio toapproximately 1/10 of its size without any significant loss of audioquality.Pan & Scan/LetterboxIn general, DVD-Video are produced with the intention that they willbe viewed on a widescreen TV (16:9 aspect ratio), so images oftendon’t fit regular TVs (4:3 aspect ratio). 2 styles of picture, “Pan &Scan” and “Letterbox”, deal with this problem.Pan & Scan: The sides are cut off so the picturefills the screen.Letterbox: Black bands appear at the top andbottom of the picture so the pictureitself appears in an aspect ratio of16:9.Playback control (PBC)If a Video CD has playback control, you can select scenes andinformation with menus.(The unit is compatible with version 2.0 and 1.1.)••Glossary
