Panasonic SC-HT892 Operating Instructions Manual

RQT880438 GlossaryGlossaryCPPM (Content Protection for Prerecorded Media)A copy protection system used for DVD-Audio files. This unit supportsCPPM.DecoderA decoder restores the coded audio signals on DVDs to normal. This iscalled decoding.DivXDivX is a popular media technology created by DivX, Inc. DivX media filescontain highly compressed video with high visual quality that maintains arelatively small file size.Dolby DigitalThis is a method of coding digital signals developed by DolbyLaboratories. Apart from stereo (2-channel) audio, these signals can alsobe multi-channel audio. A large amount of audio information can berecorded on one disc using this method.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 thatcan be heard above the noise of the equipment and the highest level ofsound before distortion occurs.Film and videoDVD-Videos are recorded using either film or video. This unit candetermine which type has been used, then uses the most suitable methodof progressive output.Film: Recorded at 25 frames per second (PAL discs) or 24 frames persecond (NTSC discs). (NTSC discs recorded at 30 frames persecond as well).Generally appropriate for motion picture films.Video: Recorded at 25 frames/50 fields per second (PAL discs) or30 frames/60 fields per second (NTSC discs). Generallyappropriate for TV drama programs or animation.Frame still and field stillFrames are the still pictures that go together to make a moving picture.There are about 30 frames shown each second.One frame is made up of two fields. A regular television shows thesefields one after the other to create frames.A still is shown when you pause a moving picture. A frame still is made upof two alternating fields, so the picture may appear blurred, but overallquality is high.A field still is not blurred, but it has only half the information of a frame stillso picture quality is lower.HDMI (High-Definition Multimedia Interface)HDMI is a next-generation digital interface for consumer electronicproducts. Unlike conventional connections, it transmits uncompresseddigital video and audio signals on a single cable. This unit supports high-definition video output (720p,1080i) from the HDMI AV OUT terminal. Toenjoy high-definition video, a high-definition compatible television isrequired.I/P/BMPEG 2, the video compression standard adopted for use withDVD-Video, codes frames using these 3 picture types.I: Intra coded pictureThis picture has the best quality and is the best to use when adjustingthe picture.P: Predictive coded pictureThis picture is calculated based on past I- or P-pictures.B: Bidirectionally-predictive coded pictureThis picture is calculated by comparing past and future I- andP-pictures so it has the lowest volume of information.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 benefit of JPEG isless deterioration in picture quality considering the degree ofcompression.Linear PCM (pulse code modulation)These are uncompressed digital signals, similar to those found on CDs.MP3 (MPEG Audio Layer 3)An audio compression method that compresses audio to approximatelyone tenth of its size without any considerable loss of audio quality.MPEG4A compression system for use on mobile devices or a network, that allowshighly efficient recording at a low bit rate.Playback control (PBC)If a Video CD has playback control, you can select scenes andinformation with menus.Progressive/InterlacedThe PAL video signal standard has 576 interlaced (i) scan lines, whereasprogressive scanning, called 576p, uses twice the number of scan lines.For the NTSC standard, these are called 480i and 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.Sampling frequencySampling is the process of converting the heights of sound wave (analogsignal) samples taken at set periods into digits (digital encoding).Sampling frequency is the number of samples taken per second, so largernumbers mean more faithful reproduction of the original sound.WMA (Windows Media TM Audio)WMA is a compression format developed by Microsoft Corporation. Itachieves the same sound quality as MP3 with a file size that is smallerthan that of MP3.
