Such broadcasts can be recorded only with CPRMcompatible recorders and discs.DecoderA decoder restores the coded audio signals on DVDs to normal. This iscalled decoding.Dolby DigitalThis is a method of coding digital signals developed by Dolby Laboratories.Apart from stereo (2-channel) audio, these signals can also be multichannelaudio. A large amount of audio information can be recorded on one discusing this method.Dolby Pro LogicA surround system where a 4-channel audio track is recorded as 2 channelsand then is restored to 4 channels for play. The surround channel ismonaural and can reproduce up to 7 kHz.Down-mixingThis is the process of remixing the multi-channel audio found on some discsinto two channels for stereo output. It is useful when you want to listen to the5.1-channel audio recorded on DVDs through your television’s speakers.Some discs prohibit down-mixing and this unit can then only output the fronttwo channels.DPOF (Digital Print Order Format)DPOF is the standard printing format for still picture data. It is used byphoto developing stores to print out the still picture data taken from a digitalcamera and other equipment or when printing from your home printer.DTS (Digital Theater Systems)This surround system is used in many movie theaters around the world.There is good separation between the channels, so realistic sound effectsare possible.Dynamic rangeDynamic range is the difference between the lowest level of sound that canbe heard above the noise of the equipment and the highest level of soundbefore distortion occurs. Dynamic range compression means reducing thegap between the loudest and softest sounds. This means you can listen atlow volumes but still hear dialog clearly.Film and videoDVD-Videos are recorded using either film or video. This unit can determinewhich type has been used, then uses the most suitable method ofprogressive output.• Film 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 or DVD-R etc.possible on equipment that can play such media. You can finalize DVD-R onthis unit.You cannot record onto or edit finalized discs.FormattingFormatting is the process of making media such as DVD-RAM recordableon recording equipment. You can format the DVD-RAM on this unit.Formatting erases irrevocably all recordings on the disc.Frames and fieldsFrames refer to the single images that constitute the video you see on yourtelevision. Each frame consists of two fields.• A frame still shows two fields, so there may be some blurring, but picturequality is generally better.• A field still shows less picture information so it may be rougher, but there isno blurring.JPEG (Joint Photographic Experts Group)This is a system used for compressing/decoding color still pictures. If youselect JPEG as the storage system on digital cameras etc., the data willbe compressed to 1/10–1/100 of its original size. The special quality of thisstandard is that there is little deterioration in picture quality in comparison tothe degree of compression.LPCM (Linear pulse code modulation)These are uncompressed digital signals. This unit outputs linear PCM soundin 2 channels from the DIGITAL AUDIO OUT terminal. LPCM sound isavailable when recording in XP mode.MP3 (MPEG Audio Layer 3)An audio compression method that compresses audio to approximately onetenth of its size without any considerable loss of audio quality. You can playMP3 you have recorded onto CD-R and CD-RW.Playback control (PBC)If a Video CD has playback control, you can select scenes and informationwith menus.Progressive/InterlaceNTSC, the video signal standard, has 480 interlaced (I) scan lines, whereasprogressive scanning uses twice the number of scan lines. This is called480P.Using progressive output, you can enjoy the high-resolution video recordedon media such as DVD-Video.Your television must be compatible to enjoy progressive video.ProtectionYou can prevent accidental erasure by setting writing protection or erasureprotection.Sampling frequencySampling is the process of converting the heights of sound wave (analogsignal) samples taken at set periods into digits (digital encoding). Samplingfrequency is the number of samples taken per second, so larger numbersmean more faithful reproduction of the original sound.SubtitlesWhen dialogue which appears at the bottom of the screen.TIFF (Tag Image File Format)A still picture data standard A common format for storing high quality imageson digital camera’s and other devices.VBR (Variable bitrate)This is a method of video recording that adjusts the bit rate according tovideo signal.Glossary= +Frame Field Field
