35、 signal format developed by Digital TheaterSystems Inc. While offering high compatibility withthe conventional DTS Digital Surround format,DTS-ES Extended Surround greatly improves the360-degree surround impression and spaceexpression thanks to further expanded surroundsignals. This format has been

36、used professionallyin movie theaters since 1999.In addition to the 5.1 surround channels (FL, FR,C, SL, SR and LFE), DTS-ES Extended Surroundalso offers the SB (Surround Back) channel forsurround playback with a total of 6.1 channels.DTS-ES Extended Surround includes two signalformats with different

37、 surround signal recordingmethods, as DTS-ES Discrete 6.1 and DTS-ESMatrix 6.1.“DTS”, “DTS-ES” and “Neo:6” are trademarks ofDigital Theater Systems, Inc.The stereo CD is a 16-bit medium with sampling at44.1 kHz. Professional audio has been 20- or 24-bit for some time, and there is increasing interes

38、t inhigher sampling rates both for recording and fordelivery into the home. Greater bit depths provideextended dynamic range. Higher sampling ratesallow wider frequency response and the use ofanti-alias and reconstruction filters with morefavorable aural characteristics.DTS 96/24 allows for 5.1chann

39、el sound tracks tobe encoded at a rate of 96kHz/24bits on DVD-Video titles.When DVD-video appeared, it became possible todeliver 24-bit, 96 kHz audio into the home, but onlyin two channels, and with serious limitations onpicture. This capability has had little use.DVD-audio allows 96/24 in six chann

40、els, but a newplayer is needed, and only analog outputs areprovided, necessitating the use of the D/A convertersand analog electronics provided in the player.DTS 96/24 offers the following:1. Sound quality transparent to the original 96/24master.2.Full backward compatibility with all existingdecoder

No new player required: DTS 96/24 can becarried on DVD-video, or in the video zone ofDVD-audio, accessible to all DVD players.4. 96/24 5.1-channel sound with full-quality full-motion video, for music programs and motionpicture soundtracks on DVD-vi

43、 designed tocreate full range digital sound reproduction.The no compromise DTS digital process sets thestandard of quality for cinema sound by deliveringan exact copy of the studio master recordings toneighborhood and home theaters.Now, every moviegoer can hear the sound exactlyas the moviemaker int

45、nnel,there remains a need for high-quality matrix decoding.This is because of the large library of matrix surroundmotion pictures available on disc and on VHS tape;and analog television broadcasts.The typical matrix decoder of today derives acenter channel and a mono surround channel fromtwo-channel

46、 matrix stereo material. It is better thana simple matrix in that it includes steering logic toimprove separation, but because of its mono,band-limited surround it can be disappointing tousers accustomed to discrete multichannel.Neo:6 offers several important improvements asfollow, Neo:6 provides up

47、 to six full-band channels ofmatrix decoding from stereo matrix material.Users with 6.1 and 5.1 systems will derive sixand five separate channels, respectively,corresponding to the standard home-theaterspeaker layouts.Neo:6 technology allows various sound elementswithin a channel or channels to be s

48、teeredseparately, and in a way which follows naturallyfrom the original presentation.Neo:6 offers a music mode to expand stereononmatrix recordings into the five- or six-channellayout, in a way which does not diminish the subtletyand integrity of the original stereo recording.2. TECHNICAL DESCRIPTIO

49、N4Circle Surround II (CS-II) is a powerful and versatilemultichannel technology. CS-II is designed toenable up to 6.1 multichannel surround soundplayback from mono, stereo, CS encoded sourcesand other matrix encoded sources. In all cases thedecoder extends it into 6 channels of surroundaudio and a L

The CS-IIdecoder creates a listening environment thatplaces the listener “inside” music performancesand dramatically improves both hi-fi audioconventional surround-encoded video material.CS-II provides composite stereo rear channels togreatly improve separation and image positio
