68RQT8203GlossaryBitstreamThis is the digital form of multi-channel audio data (e.g., 5.1 channel)before it is decoded into its various channels.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.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 television’sspeakers. Some discs prohibit down-mixing and this unit can thenonly output the front two channels.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.DriveIn the instance of this unit, this refers to the hard disk (HDD), disc(DVD) and SD card (SD). These perform the reading and writing ofdata.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 compression means reducing the gap between theloudest and softest sounds. This means you can listen at lowvolumes but still hear dialogue clearly.Electronic Programme Guide (EPG)This is a system used to display the television programme list ontelevisions, computers and cellular phones. Data is transmitted usingthe internet or television waves. This unit is compatible with themethod using television waves. You can use the televisionprogramme list for functions such as timer recording.Film and videoDVD-Videos are recorded using either film or video. This unit candetermine which type has been used, then uses the most suitablemethod of progressive output.For PALFilm is 25 frames per second.Video is 50 fields per second (two fields making up one frame).For NTSCFilm is 24 or 30 frames per second, with motion picture film generallybeing 24 frames per second.Video is 60 fields per second (two fields making up one 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 can finalizeDVD-R, DVD-RW (DVD-Video format), +R on this unit.After finalizing, the disc becomes play-only and you can no longerrecord or edit. However, finalized DVD-RW can be formatted tobecome recordable.FolderThis is a place on the hard disk or memory card where groups ofdata are stored together. In the case of this unit, it refers to the placewhere still pictures (JPEG, TIFF) are stored.FormattingFormatting is the process of making media such as DVD-RAMrecordable on recording equipment.You can format the HDD, DVD-RAM, DVD-RW (only as DVD-Videoformat) and SD Memory Card on this unit. Formatting erasesirrevocably all contents.Frames and fieldsFrames refer to the single images that constitute the video you seeon your television. Each frame consists of two fields.≥A frame still shows two fields, so there may be some blurring, butpicture quality is generally better.≥A field still shows less picture information so it may be rougher, butthere is no blurring.HDD (Hard disk drive)This is a mass data storage device used in computers, etc. A diskwith a surface that has been treated with magnetic fluid is spun anda magnetic head is brought in close proximity to facilitate the readingand writing of large amounts of data at high speed.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 consideringthe degree of compression.LPCM (Linear PCM)These are uncompressed digital signals, similar to those found onCDs. LPCM sound is available when recording in XP mode.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 MP3 you have recorded onto CD-R andCD-RW.Pan&Scan/LetterboxIn general, DVD-Video are produced with the intention that they beviewed on a widescreen television (16:9 aspect ratio), so imagesoften don’t fit regular (4:3 aspect ratio) televisions. Two styles ofpicture, “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.(This unit is compatible with version 2.0 and 1.1.)Progressive/InterlaceThe PAL video signal standard has 625 (or 576) interlaced (i) scanlines, whereas progressive scanning, called 625p (or 576p), usestwice the number of scan lines. For the NTSC standard, these arecalled 525i (or 480i) and 525p (or 480p) respectively.Using progressive output, you can enjoy the high-resolution videorecorded on media such as DVD-Video.Your television must be compatible to enjoy progressive video.Panasonic televisions with 625 (576)/50i · 50p, 525 (480)/60i · 60pinput terminals are progressive compatible.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 colour still pictures,a common format for storing high quality images on digital camerasand other devices.u rFrame Field FieldGlossary68
