28、ped by Digital Theater Systems Inc. While offering high compatibility with the conventional DTS Digital Surround format, DTS-ES Extended Surround greatly improves the 360-degree surround impression and space expression thanks to further expanded surround signals. This format has been used profession

29、ally 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 surround playback with a total of 6.1 channels. DTS-ES Extended Surround includes two signal formats with different surroun

30、d signal recording methods, as DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1. “DTS”, “DTS-ES” and “Neo:6” are trademarks of Digital Theater 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, and there is increasing interest

31、 in higher sampling rates both for recording and for delivery into the home. Greater bit depths provide extended dynamic range. Higher sampling rates allow wider frequency response and the use of anti-alias and reconstruction filters with more favorable aural characteristics. DTS 96/24 allows for 5.

32、1channel sound tracks to be encoded at a rate of 96kHz/24bits on DVD- Video titles. When DVD-video appeared, it became possible to deliver 24-bit, 96 kHz audio into the home, but only in two channels, and with serious limitations on picture. This capability has had little use. DVD-audio allows 96/24

33、 in six channels, but a new player is needed, and only analog outputs are provided, necessitating the use of the D/A converters and analog electronics provided in the player. DTS 96/24 offers the following: 1. Sound quality transparent to the original 96/24 master. 2.Full backward compatibility with

34、 all existing decoders. (Existing decoders will output a 48 kHz signal) 3. No new player required: DTS 96/24 can be carried on DVD-video, or in the video zone of DVD-audio, accessible to all DVD players. 4. 96/24 5.1-channel sound with full-quality full- motion video, for music programs and motion p

35、icture soundtracks on DVD-video. “DTS” and “DTS 96/24” are trademarks of Digital Theater Systems, Inc. 2 DTS was introduced in 1994 to provide 5.1 channels of discrete digital audio into home theater systems. DTS brings you premium quality discrete multichannel digital sound to both movies and music

36、. DTS is a multichannel 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 h

37、ear the sound exactly as the moviemaker 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 Digital Theater Systems, Inc. The advantages of discrete multichannel systems over matrix are well known

38、. But even 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 ce

39、nter channel 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 multichannel. Neo:6 off

40、ers several 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 five separate channels, respectively, corresponding to the standard home-theater speaker layouts. Neo:6 technol

41、ogy allows 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 five- or six-channel layout, in a way which does not diminish the sub

42、tlety and integrity of the original stereo recording. 2. TECHNICAL DESCRIPTION 4 Circle Surround II (CS-II) is a powerful and versatile multichannel technology. CS-II is designed to enable up to 6.1 multichannel surround sound playback from mono, stereo, CS encoded sources and other matrix encoded s

43、ources. In all cases the decoder extends it into 6 channels of surround audio and a LFE/subwoofer signal. The CS-II decoder creates a listening environment that places the listener “inside” music performances and dramatically improves both hi-fi audio conventional surround-encoded video material. CS

44、-II provides composite stereo rear channels to greatly improve separation and image positioning adding a heightened sense of realism to both audio and A/V productions. CS-II is packed with other useful feature like dialog clarity (SRS Dialog) for movies and cinema-like bass enrichment (TruBass). CS-II can enable the dialog to become clearer and more discernable in movies and it enables the bass frequencies contained in the original programming to more closely achieve low frequencies overcoming the low frequency limitations of the speakers by full octave.
