This isbecause of the large library of matrix surround motion picturesavailable on disc and on VHS tape; and analog televisionbroadcasts.The typical matrix decoder of today derives a center channeland a mono surround channel from two-channel matrixstereo material. It is better than a simple matrix in that itincludes steering logic to improve separation, but because ofits mono, band-limited surround it can be disappointing tousers accustomed to discrete multichannel.Neo:6 offers several important improvements as follow, Neo:6 provides up to six full-band channels of matrixdecoding from stereo matrix material. Users with 6.1 and5.1 systems will derive six and five separate channels,respectively, corresponding to the standard home-theaterspeaker layouts.Neo:6 technology allows various sound elements within achannel or channels to be steered separately, and in a waywhich follows naturally from the original presentation.Neo:6 offers a music mode to expand stereo nonmatrixrecordings into the five- or six-channel layout, in a way whichdoes not diminish the subtlety and integrity of the originalstereo recording.DTS-ES Extended Surround is a new multichannel digitalsignal format developed by Digital Theater Systems Inc.While offering high compatibility with the conventional DTSDigital Surround format, DTS-ES Extended Surround greatlyimproves the 360-degree surround impression and spaceexpression thanks to further expanded surround signals.This format has been used professionally in movie theaterssince 1999.In addition to the 5.1 surround channels (FL, FR, C, SL, SRand LFE), DTS-ES Extended Surround also offers the SB(Surround Back) channel for surround playback with a totalof 6.1 channels. DTS-ES Extended Surround includes twosignal formats with different surround signal recordingmethods, as DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1.“DTS”, “DTS-ES” and “Neo:6” are trademarks of DigitalTheater Systems, Inc.The stereo CD is a 16-bit medium with sampling at 44.1 kHz.Professional audio has been 20- or 24-bit for some time, andthere is increasing interest in higher sampling rates both forrecording and for delivery into the home. Greater bit depthsprovide extended dynamic range. Higher sampling ratesallow wider frequency response and the use of anti-alias andreconstruction filters with more favorable auralcharacteristics.DTS 96/24 allows for 5.1channel sound tracks to beencoded at a rate of 96kHz/24bits on DVD-Video titles.When DVD-video appeared, it became possible to deliver24-bit, 96 kHz audio into the home, but only in two channels,and with serious limitations on picture. This capability hashad little use.DVD-audio allows 96/24 in six channels, but a new player isneeded, and only analog outputs are provided, necessitatingthe use of the D/A converters and analog electronicsprovided in the player.DTS 96/24 offers the following:1.Sound quality transparent to the original 96/24 master.2.Full backward compatibility with all existing decoders.(Existing decoders will output a 48 kHz signal)3.No new player required: DTS 96/24 can be carried onDVD-video, or in the video zone of DVD-audio, accessibleto all DVD players.4.96/24 5.1-channel sound with full-quality full-motion video,for music programs and motion picture soundtracks onDVD-video.“DTS” and “DTS 96/24” are trademarks of Digital TheaterSystems, Inc.2. TECHNICAL DESCRIPTION4Dolby Digital identifies the use of Dolby Digital audio codingfor such consumer formats as DVD and DTV. As with filmsound, Dolby Digital can provide up to five full-rangechannels for left, center, and right screen channels,independent left and right surround channels, and a sixth(“.1”) channel for low-frequency effects.Dolby Surround Pro Logic II is an improved matrix decodingtechnology that provides better spatiality and directionalityon Dolby Surround program material; provides a convincingthree-dimensional soundfield on conventional stereo musicrecordings; and is ideally suited to bring the surroundexperience to automo
