68RQT7394ReferenceGlossaryBitstreamThis 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.DHCP (Dynamic Host Configuration Protocol)Provides a mechanism for automatically assigning networkinformation such as the IP address or Subnet mask sent by therouter and so on to this unit.DNS ServerA server which acts like a telephone directory and translates Internetdomain names into IP addresses.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 DVD-Audio prevent down-mixing of all or part oftheir contents. When playing such discs, or such parts of the disc,unless the number of connected speakers is the same as the disc’schannel specification, audio will not be output properly.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), SD card (SD) and PC card (PC). These perform the readingand writing of data.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 dialog clearly.Film and videoDVD-Video are recorded using either film or video. This 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 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 on this unit.After finalizing, the disc becomes play-only and you can no longerrecord or edit.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) or MPEG4 are stored.FormattingFormatting is the process of making media such as DVD-RAMrecordable on recording equipment.You can format the HDD, DVD-RAM and memory cards on this unit.Formatting erases irrevocably 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.GatewayIP address of the electronic device providing Internet access.Usually called a router IP address. (e.g., 192.168.0.1)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.HubUsed for connecting more than one device to the network.IP addressA set of numbers which distinguish each computer on the networkwhen, for example, connected to the Internet. When using acomputer in a LAN (➡ below) to access a computer or device notpart of the LAN, the IP address is called the local IP address. (e.g.,192.168.0.10)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. Thefeature of JPEG is less deterioration in picture quality consideringthe degree of compression.LAN (Local Area Network)A group of linked devices in a company, school or home. Indicatesthe boundaries of a particular network.LPCM (Linear PCM)These are uncompressed digital signals, similar to those found onCDs. LPCM sound is available when recording in XP mode.MAC (Media Access Control) addressAddress assigned to each device connected to the network to allowit to be recognized.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.MPEG2/MPEG4 (Moving Picture Experts Group)A standard for efficiently compressing and expanding color video.MPEG2 is a compression standard used for DVD and satellite baseddigital broadcasting. This unit records programs using MPEG2.MPEG4 is a compression standard created for use with mobileequipment and use over networks, providing highly efficient record-ings even with low bit rates.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.Frame Field Fieldu r
