76RQTV0141GlossaryBitstreamThis 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.CPPM (Content Protection for Prerecorded Media)A copy protection system used for DVD-Audio files. This unitsupports CPPM.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.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’sspeakers. Some discs prohibit down-mixing. If this is the case, thisunit can only output the front two channels.Tracks that do not allow down-mixing will not play correctly on thisunit except when connecting with an HDMI cable to an amplifier thatmeets HDMI Ver. 1.1 standards and is CPPM compatible.DPOF (Digital Print Order Format)DPOF is the standard printing format for still picture data taken by adigital camera, etc. It is used for automatic printing at a photodeveloping store or on your home printer.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 dialog 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 is 24 or 30 frames per second, with motion picture filmgenerally being 24 frames per second.≥Video is 60 fields per second (2 fields making up 1 frame).FinalizeA process that makes play of a recorded CD-R, CD-RW, DVD-R,etc. possible on equipment that can play such media. You canfinalize DVD-R, DVD-R DL, DVD-RW (DVD-Video format), +R and+R DL on the unit. After finalizing, the disc becomes play-only andyou can no longer record or edit. However, finalized DVD-RW canbe formatted to become recordable.FolderThis is a place on the memory card where groups of data are storedtogether. In the case of this unit, it refers to the place where stillpictures (JPEG, TIFF) are stored.FormattingFormatting is the process of making media such as DVD-RAMrecordable on recording equipment.You can format DVD-RAM and DVD-RW (only as DVD-Videoformat) or +RW and SD memory card 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 Field≥A frame still shows 2 fields, so there may be some blurringbetween them, 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)HDMI is a next-generation digital interface for consumer electronicproducts. Unlike conventional connections, it transmitsuncompressed digital video and audio signals on a single cable. Thisunit supports high-definition video output (720p, 1080i) from HDMIAV OUT terminals. To enjoy high-definition video a high definitioncompatible television is required.JPEG (Joint Photographic Experts Group)This is a system used for compressing/decoding color still pictures. Ifyou select JPEG as the storage system on digital cameras, etc., thedata will be compressed to 1/10–1/100 of its original size. Thebenefit of JPEG is less deterioration in picture quality consideringthe degree of compression.MP3 (MPEG Audio Layer 3)An audio compression method that compresses audio toapproximately one-tenth of its size without any considerable loss ofaudio quality. You can play MP3s you have recorded onto CD-R andCD-RW.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 picture fills the screen.Letterbox: Black bands appear at the top and bottom of thepicture so the picture itself appears in an aspectratio of 16:9.Playback control (PBC)If a Video CD has playback control, you can select scenes andinformation with menus displayed on the screen.(The unit is compatible with version 2.0 and 1.1.)Progressive/InterlaceNTSC, the video signal standard, has 480 interlaced (i) scan lines,whereas progressive scanning uses twice the number of scan lines.This is called 480p.Using progressive output, you can enjoy the high-resolution videorecorded on media such as DVD-Video.Your TV must be compatible to enjoy progressive video.ProtectionYou can prevent accidental erasure by setting writing protection orerasure protection.Sampling frequencySampling is the process of converting the heights of sound wave(analog signal) samples taken at set periods into digits (digitalencoding). Sampling frequency is the number of samples taken persecond, so larger numbers mean more faithful reproduction of theoriginal sound.ThumbnailThis refers to a miniature representation of a picture used to displaymultiple pictures in the form of a list.TIFF (Tag Image File Format)This is a system used for compressing/decoding color still pictures, acommon format for storing high quality images on digital camerasand other devices.= +
