85RQT9414ReferenceGlossaryBitstreamThis 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.Deep ColourThis unit incorporates HDMI TM (V.1.3a with Deep Colour) technologythat can reproduce greater colour gradation (4096 steps) whenconnected to a compatible TV. You can enjoy exceptionally rich,natural-looking colours, with smooth, detailed gradation and minimalcolour banding. [A lower colour gradation (256 steps), without DeepColour, will be reproduced if connected to a TV which does notsupport Deep Colour. The unit will automatically set appropriateoutput to suit the connected TV.]DivXDivX is a popular media technology created by DivX, Inc. DivXmedia files contain highly compressed video with high visual qualitythat maintains a relatively small file size.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 informationcan be 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.DriveIn the instance of this unit, this refers to the hard disk (HDD), disc(DVD) and SD card (SD) ([EX89]). These perform the reading andwriting 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 dialogue clearly.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.FinaliseA process that makes play of a recorded CD-R, CD-RW, DVD-R,etc. possible on equipment that can play such media. You canfinalise DVD-R, DVD-R DL, DVD-RW (DVD-Video format), +R, +RDL on this unit.After finalising, the disc becomes play-only and you can no longerrecord or edit. However, finalised DVD-RW can be formatted forrecording again.FolderThis is a place on the hard disk, disc or SD card ([EX89]) wheregroups of data are stored together. In the case of this unit, it refers tothe place where still pictures (JPEG) and MPEG2 are stored.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),+RW, SD cards ([EX89]) and the HDD or unused +R and +R DL onthis unit.Formatting permanently deletes 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.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), 1080p (1125p)]from HDMI AV OUT terminals. To enjoy high-definition video a highdefinition 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 consideringthe degree 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.SD Video files shot with a Panasonic SD video camera, etc. can becopied to the HDD or a DVD-RAM disc.MP3 (MPEG Audio Layer 3)An audio compression method that compresses audio toapproximately one tenth of its size without any considerable loss ofaudio quality.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.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 576 (or 625) interlaced (i) scanlines, whereas progressive scanning, called 576p (or 625p), usestwice the number of scan lines. For the NTSC standard, these arecalled 480i (or 525i) and 480p (or 525p) 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 576 (625)/50i · 50p, 480 (525)/60i · 60pinput terminals are progressive compatible.Film: Recorded at 25 frames per second (PAL discs) or 24frames per second (NTSC discs). (NTSC discsrecorded at 30 frames per second as well.)Generally appropriate for motion picture films.Video: Recorded at 25 frames/50 fields per second. (PALdiscs) or 30 frames/60 fields per second (NTSC discs).Generally appropriate for TV drama programmes oranimation.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.u rFrame Field Field
