40、 is a multi-channel sound system designed to create full range digital sound reproduction.The no compromise DTS digital process sets the standard of quality for cinema sound by delivering an exact copy of the studio master recordings to neighborhood and home theaters.Now, every moviegoer can hear th

41、e sound exactly as the movie-maker intended.DTS can be enjoyed in the home for either movies or music on of DVDs, LDs, and CDs.“DTS” and “DTS Digital Surround” are registered trademarks of Digi-tal Theater Systems, Inc.The advantages of discrete multichannel systems over matrix are well known.But ev

42、en in homes equipped for discrete multichannel, there remains a need for high-quality matrix decoding. This is because of the large library of matrix surround motion pictures available on disc and on VHS tape; and analog television broadcasts.The typical matrix decoder of today derives a center chan

43、nel and a mono surround channel from two-channel matrix stereo material. It is better than a simple matrix in that it includes steering logic to improve separation, but because of its mono, band-limited surround it can be disappointing to users accustomed to discrete multichan-nel.Neo 6 offers sever

44、al important improvements as follow,. Neo 6 provides up to six full-band channels of matrix decoding from stereo matrix material. Users with 6.1 and 5.1 systems will derive six and fi ve separate channels, respectively, corresponding to the standard home-theater speaker layouts. Neo 6 technology all

45、ows various sound elements within a channel or channels to be steered separately, and in a way which follows naturally from the original presentation. Neo 6 offers a music mode to expand stereo nonmatrix recordings into the fi ve- or six-channel layout, in a way which does not diminish the subtlety

46、and integrity of the original stereo recording.DTS-ES Extended Surround is a new multi-channel digital signal format developed by Digital Theater Systems Inc. While offering high compatibility with the conventional DTS Digital Surround format, DTSES Extended Surround greatly improves the 360-degree

47、sur-round impression and space expression thanks to further expanded surround signals. This format has been used professionally in movie theaters since 1999.In addition to the 5.1 surround channels (FL, FR, C, SL, SR and LFE), DTS-ES Extended Surround also offers the SB (Surround Back) channel for s

48、urround playback with a total of 6.1 channels. DTS-ES Extended Surround includes two signal formats with differ-ent surround signal recording methods, as DTS-ES Discrete 6.1 and DTSES Matrix 6.1.“DTS”, “DTS-ES Extended Surround” and “Neo:6” are trademarks of Digital Theater Systems, Inc.2. TECHNICAL

49、 DESCRIPTIONDolby Digital identifi es the use of Dolby Digital (AC-3) audio coding for such consumer formats as DVD and DTV. As with fi lm sound, Dolby Digital can provide up to fi ve full-range channels for left, center, and right screen channels, independent left and right sur-round channels, and

50、a sixth ( “.1”) channel for low-frequency effects.Dolby Surround Pro Logic II is an improved matrix decoding tech-nology that provides better spatiality and directionality on Dolby Sur-round program material; provides a convincing three-dimensional soundfi eld on conventional stereo music recordings
