En 76APPENDIXAudio informationAudio and video synchronization (lip sync)Lip sync, an abbreviation for lip synchronization, is a technical term thatinvolves both a problem, and the capability of maintaining audio and videosignals synchronized during post-production and transmission.Whereas the audio and video latency requires complex end-useradjustment, HDMI version 1.3 incorporates an automatic audio and videosyncing capability that allows devices to perform this synchronizationautomatically and accurately without user interaction.Bi-amplification connectionA bi-amplification connection uses two amplifiers for a speaker. Oneamplifier is connected to the woofer section of a loudspeaker while theother is connected to the combined mid and tweeter section. With thisarrangement each amplifier operates over a restricted frequency range. Thisrestricted range presents each amplifier with a much simpler job and eachamplifier is less likely to influence the sound in some way.Dolby DigitalDolby Digital is a digital surround sound system that gives you completelyindependent multi-channel audio. With 3 front channels (front L/R andcenter), and 2 surround stereo channels, Dolby Digital provides 5 full-rangeaudio channels. With an additional channel especially for bass effects,referred to as LFE (Low-Frequency Effect), the system has a total of 5.1-channels (LFE is counted as 0.1 channel). By using 2-channel stereo for thesurround speakers, more accurate moving sound effects and surround soundenvironments are possible than with Dolby Surround. The wide dynamicrange from maximum to minimum volumes that are reproduced by the 5full-range channels, and the precise sound orientation generated usingdigital sound processing provides listeners with unprecedented excitementand realism. With this unit, any sound environment from monaural up to a5.1-channel configuration can be freely selected for your enjoyment.Dolby Pro Logic IIDolby Pro Logic II is an improved technique used to decode vast numbersof existing Dolby Surround sources. This new technology enables a discrete5-channel playback with 2 front left and right channels, 1 center channel,and 2 surround left and right channels, instead of only 1 surround channelfor conventional Pro Logic technology. There are three modes available:“Music mode” for music sources, “Movie mode” for movie sources, and“Game mode” for game sources.Dolby Pro Logic IIxDolby Pro Logic IIx is a new technology enabling discrete multichannelplayback from 2-channel or multi-channel sources. There are three modesavailable: “Music mode” for music sources, “Movie mode” for moviesources (for 2-channel sources only) and “Game mode” for game sources.Dolby SurroundDolby Surround uses a 4-channel analog recording system to reproducerealistic and dynamic sound effects: 2 front left and right channels (stereo),a center channel for dialog (monaural), and a surround channel for specialsound effects (monaural). The surround channel reproduces sound within anarrow frequency range. Dolby Surround is widely used with nearly allvideo tapes and laser discs, as well as in many TV and cable broadcasts.The Dolby Pro Logic decoder built into this unit employs a digital signalprocessing system that automatically stabilizes the volume on each channelto enhance moving sound effects and directionality.Dolby TrueHDDolby TrueHD is an advanced lossless audio technology developed forhigh-definition disc-based media including Blu-ray Disc. Selected as anoptional audio standard for Blu-ray Disc, this technology delivers soundthat is bit-for-bit identical to the studio master, offering a high-definitionhome theater experience. Supporting bitrates up to 18.0 Mbps, DolbyTrueHD can carry up to 8 discrete channels of 24-bit/96 kHz audiosimultaneously. Dolby TrueHD also remains fully compatible with theexisting multichannel audio systems and retains the metadata capability ofDolby Digital, allowing dialog normalization and dynamic range control.DTS 96/24DTS 96/24 offers an unprecedented level of audio quality for multichannelsound on DVD video, and is fully backward-compatible with all DTSdecoders. “96” refers to a 96 kHz sampling rate compared to the typical48 kHz sampling rate. “24” refers to 24-bit word length. DTS 96/24 offerssound quality transparent to the original 96/24 master, and 96/24 5.1-channel sound with full-quality full-motion video for music programs andmotion picture soundtracks on DVD video.DTS Digital SurroundDTS Digital Surround was developed to replace the analog soundtracks ofmovies with a 5.1-channel digital sound track, and is now rapidly gainingpopularity in movie theaters around the world. DTS, Inc. has developed ahome theater system so that you can enjoy the depth of sound and naturalspatial representation of DTS Digital Surround in your home. This systemproduces practically distortion-free 5.1-channel sound (technically, left,right and center channels, 2 surround channels, plus an LFE 0.1 channel asa subwoofer, for a total of 5.1-channels).DTS ExpressThis is an audio format for next-generation optical discs such as Blu-raydiscs. It uses optimized low bit rate signals for network streaming. In thecase of a Blu-ray disc, this format is used with secondary audio, enablingyou to enjoy the commentary of the movie producer via the Internet whileplaying the main program.DTS-HD High Resolution AudioDTS-HD High Resolution Audio is a high resolution audio technologydeveloped for high-definition disc-based media including Blu-ray Disc.Selected as an optional audio standard for Blu-ray Disc, this technologydelivers sound that is virtually indistinguishable from the original, offeringa high-definition home theater experience.Supporting bitrates up to 6.0 Mbps for Blu-ray Disc, DTS-HD HighResolution Audio can carry up to 7.1 discrete channels of 24-bit/96 kHzaudio simultaneously.DTS-HD High Resolution Audio also remains fully compatible with theexisting multichannel audio systems that incorporate DTS DigitalSurround.DTS-HD Master AudioDTS-HD Master Audio is an advanced lossless audio technology developedfor high-definition disc-based media including Blu-ray Disc. Selected as anoptional audio standard for Blu-ray Disc, this technology delivers soundthat is bit-for-bit identical to the studio master, offering a high-definitionhome theater experience.Supporting bitrates up to 24.5 Mbps for Blu-ray Disc, DTS-HD MasterAudio can carry up to 7.1 discrete channels of 24-bit/96 kHz audiosimultaneously. Supported by HDMI version 1.3 and designed for theoptical disc players and AV receivers/amplifiers of the future, DTS-HDMaster Audio also remains fully compatible with the existing multichannelaudio systems that incorporate DTS Digital Surround.Glossary
