Redirect from Digital Theater System[edit]

Would it be appropriate to place a redirect to here from the title "Digital Theater System"? --Reverend Loki 20:53, 9 May 2006 (UTC)

That would be a good idea. Qutezuce 03:51, 10 May 2006 (UTC)

Non-NPOV or source needed[edit]

The following sentance in the DTS Variants section under "DTS-HD Master Audio" does not have a neutral point of view or is lacking a verifiable source:

"Although technically superior over its Dolby counterpart, DTS-HD Master Audio is selected only as an optional surround sound format for Blu-ray and HD-DVD."

I suggest it be changed to say:

"DTS-HD Master Audio is selected as an optional surround sound format for Blu-ray and HD-DVD."


Kirkmeyers 22:42, 27 July 2006 (UTC)

Here here. It may save some from experiencing the taste of their sole at a later date. Anyway, Sony Atrac is better than everything, isn't it?

It should be noted that a vast majority of the "History" section is a word for word snip from http://firstdtsstudio.hit.bg/faq_dts_eng.html —Preceding unsigned comment added by 76.30.70.228 (talk) 04:29, 7 October 2007 (UTC)

DTS CD[edit]

I have a couple of music CDs that have DTS audio, perhaps this could be elaborated on by someone who knows more about this format, and the releases, etc. Whitesanjuro 16:08, 6 September 2006 (UTC)

I sold these for a while in a high-end a/v store when they first came out. 5.1 channel and great sound. DTS cd's dont seem to have fared well in the format wars since superior audio-only formats have come out since. Consequently there are fewer releases available than audiophiles had once hoped and which a/v salespeople like me promised would materialize.Thinkenstein 09:44, 25 February 2007 (UTC)

AC-3 or AC3?[edit]

Since AC-3 and AC3 is absolutely the same thing, I can't see a reason why not to go with "AC3" in this article since it's IMO used much more frequently. Is there any reason why not to do so? Is AC-3 any more correct or something?

The Dolby Digital article always refers to it as AC-3 so I think that's the correct way to refer to it. Thunderhawk89 15:01, 7 March 2007 (UTC)

Why refer to any non-DTS technology at all, much less debate acronyms of non-DTS technology...

Selling Cinema and Digital Images[edit]

DTS has announced that it's selling it's cinema and digital images divisions. (Digital Images was formerly known as Lowry Digital). 201.141.65.186Anonymouse.

Separate variant articles[edit]

Wouldn't it be more interesting to have separate articles for each codec? And just a basic comparison here in this article perhaps? Or a codec listing... Thunderhawk89 15:01, 7 March 2007 (UTC)

DTS-HD Variants[edit]

I believe DTS-HD and DTS-HDMA aren't the same. DTS-HD Master Audio is capable of delivering audio that is a bit-for-bit identical to the studio master. DTS-HD Master Audio delivers audio at super high variable bit rates -24.5 mega-bits per second (Mbps) on Blu-ray discs and 18.0 Mbps on HD-DVD - that are significantly higher than standard DVDs . This bit stream is so "fast" and the transfer rate is so "high" that it can deliver the Holy Grail of audio: 7.1 audio channels at 96k sampling frequency/24 bit depths that are identical to the original. With DTS-HD Master Audio, you will be able to experience movies and music, exactly as the artist intended: clear, pure, and uncompromised.

DTS-HD High Resolution Audio can deliver up to 7.1 channels of sound that is virtually indistinguishable from the original. DTS-HD High Resolution Audio delivers audio at high constant bit rates superior to standard DVDs---6.0 Mbps on Blu-ray discs and 3.0 Mbps on HD-DVD to produce outstanding sound quality. It is capable of delivering up to 7.1 channels at 96k sampling frequency/24 bit depth resolution. It allows content creators to deliver rich, high definition audio on movies where disc space may not allow for DTS-HD Master Audio. From the original DTS website.

DTS in DVD's[edit]

Of late I have noticed that DVD's released in INDIA do not have DTS encoding. Only Dolby Digital(AC-3) is provided!!

Any idea?!!

Company name[edit]

The wiki page says DTS is aka "Digital Theater Systems". Does anyone have a reference for that? Their company page only indicates DTS. Mmernex 15:43, 17 August 2007 (UTC)

Sure. Try [1] DTS-6D INSTALLATION AND OPERATION MANUAL 35MM October 16, 1998. Digital Theater Systems. 5171 Clareton Drive. Agoura Hills, CA 91301, USA.
Or, you could look at this text from the 10-K for 2006:
The Company commenced operations in 1990 as Digital Theater Systems Corporation ("DTS Corp"). In 1993, DTS Corp became the general partner of Digital Theater Systems, L.P., a Delaware limited partnership ("the Partnership"). In 1994, the Partnership formed DTS Technology, LLC ("DTS Technology") to develop audio technologies for the consumer electronics and other markets. On October 24, 1997 the Company completed a reorganization and tax-free exchange with the predecessor entities and was incorporated in Delaware. The reorganization and formation of the Company was accounted for as a transaction by entities under common control and was effected by each of the former stockholders and owners of DTS Corp, the Partnership and DTS Technology receiving an ownership interest in the Company, represented by shares of common stock and warrants to acquire shares of common stock, substantially equivalent to their previous interests in DTS Corp, the Partnership and DTS Technology. On July 9, 2003, the Company completed its initial public offering for the sale of 4,091 shares of common stock at a price to the public of $17.00 per share. All of the shares of common stock sold in the offering were registered under the Securities Act of 1933, as amended (the "Securities Act") on a Registration Statement on Form S-1 (Reg. No. 333-104761) that was declared effective by the Securities and Exchange Commission (the "SEC") on July 9, 2003 and a Registration Statement filed pursuant to Rule 426(b) under the Securities Act that was filed on July 9, 2003 (Reg. No. 333-106920). In May 2005, the Company changed its name from Digital Theater Systems, Inc. to DTS, Inc.
In January 2007, the Company combined its Cinema and Digital Images businesses into a single business known as "DTS Digital Cinema." In February 2007, the Company's Board of Directors approved a plan to sell its DTS Digital Cinema business to enable the Company to focus exclusively on licensing branded entertainment technology to the large and evolving audio, game console, personal computer, portable, broadcast, and other markets. The sales process has begun and is expected to conclude later in 2007. For additional information, refer to Footnote 24 of the consolidated financial statements, "Subsequent Events."

Inconsistencies[edit]

According to the History of apt-X webpage of APT, Dr Stephen Smyth begun working on the fundamentals for the DTS format in the 1980s with a DSP hardware solution called APTX100ED at the end of the 1980s. According to the DTS history whitepaper the compression algorithm was demonstrated in early 1992 for Steven Spielberg using a hard drive. Universal decided to test DTS on two "minor" movies before Jurrasic Park to ensure that the technology worked (which two these were would of course be very interesting to know).

Again from the DTS history whitepaper, for the integration of the apt-X codec into practical movie use Terry Beard started working on the solution in 1972, joined by Jim Ketcham in the mid 1980s. Digital Theater Systems was founded at February 1, 1993 and was co-owned by Universal, Steven Spielberg, Terry, Jim "and others".

So the start year in the history section is if not wrong so at least misleading. It also sounds like it was Steven Speilberg who started the technology research, when it was really in a working state when he was brought in.

The section "DTS as a codec" is in its current state very questionable. To start out with a patent dispute in France is trivia and to label it as "enhanced copy" is clearly taking a side.

To label apt-X as "traditional ADPCM" is perhaps to oversimplify it, as apt-X takes four 16-bit samples and divides them into four subbands through a QMF, calculates the difference against a backward linear prediction loop and quantize the error signal with a backaward adaptive Laplacian quantizer. The bit rate of the four sub-bands, though fixed, are different due to psychoacoustic masking. (The information is from apt-X technical overview) —Preceding unsigned comment added by 213.112.15.70 (talk) 16:56, 22 September 2007 (UTC)

I need help with understanding DTS HD Master Audio[edit]

I am thinking of buying a HD TV and a Blu-ray player. I've looked on the back covers of some Blu-ray titles that list DTS HD Master Audio as the only main audio track, will DTS HD Master Audio tracks be heard on the speakers on a HD TV or do I need a surround sound system? Kieranthompson —Preceding unsigned comment added by Kieranthompson (talkcontribs) 20:23, 29 September 2007 (UTC)

Split Article?[edit]

This article should probably be about the company, with talk of the codec (and, pertinent to this article, the various extensions) left to DTS Coherent Acoustics. Thoughts? —Locke Coletc 21:10, 13 October 2007 (UTC)

I'd rather like to see an article DTS (Company), because I think most people looking up DTS are interested in the codec, so the main article should be about that. But splitting would be a good idea imo. 86.33.110.66 (talk) 12:00, 19 September 2009 (UTC)

The term 'core'[edit]

From the current revision: 'The PlayStation 3 can decode the "core" of DTS-HD internally at a bitrate of 1.5 Mbit/s while the Xbox 360 can output the bitstream itself via Toslink.' What does this mean? The 360 outputs the encoded stream, while the PS3 outputs, what, a partially decoded version? What's the practical effect? --DocumentN (talk) 02:31, 21 February 2008 (UTC)

Licence violation ?[edit]

A great part of the text is only a copy of the 1st reference (http://firstdtsstudio.hit.bg/faq_dts_eng.html) and I don't see any reuse licence on this page, so it seems to me that this is a licence violation ... —Preceding unsigned comment added by 82.236.137.143 (talk) 17:06, 15 April 2008 (UTC)

DTS Connect[edit]

I branched out DTS connect to its own section, as I was able to add the DTS Neo:PC information, and thus fully explain the DTS Connect variant. I was able to find a reference, as well as use my own knowledge of the subject. Floodo1 (talk) 00:53, 15 July 2008 (UTC)

Removed mention of stand-alone devices such as HD-DVD & Blu-ray players as using DTS Interactive, as I don't know of any devices that use this technology. It doesnt make sense that they would use this as DTS interactive is a technology that encodes multi-channel surround into DTS format, and most (if not all) HD-DVD's and Blu-ray discs would already have DTS material. Essentially the only use for this technology on such devices would be to transcode Dolby Digital formats to DTS. —Preceding unsigned comment added by Floodo1 (talkcontribs) 00:46, 15 July 2008 (UTC)

AC-3 data rate when used in 35mm film[edit]

The article, in the History section, discusses an AC-3 data rate of 448kbps and goes on to say, referring to AC-3, that "theatrical (35 mm movie) installations, which are limited to even lower bitrates." There is one data rate for theatrical print films using Dolby Digital (aka AC-3). That data rate is 320 kbps. I'm not changing it because the entire paragraph has many problems that need to be addressed. MRJayMach (talk) 20:46, 17 August 2008 (UTC)

Merger[edit]

There has been a suggestion to merge the page DTS Coherent Acoustics with DTS (sound system). Please leave a Support or Oppose at the bottom of the list and state why you did so.


  • I Support this merger. What's the point of having the DTS Coherent Acoustics page? It's simply pointless, since the information is already on DTS (sound system). I have merged the two pages together. Limetolime Talk to me look what I did! 03:16, 26 November 2008 (UTC)
  • Huh? the page was merged without even waiting a single day? That doesn't seem right. It might've been nice to've seen some discussion before the rename, too. jhawkinson (talk) 15:13, 27 November 2008 (UTC)

DTS vs Dolby Digital volume[edit]

It should be noted that a DTS soundtrack will often sound louder than the DD soundtrack on the same disc, which will make DTS seem better. DD is subject to dialnorm, where DTS is not which could be the reason for the volume difference. This can lead to an unfair comparison between the two formats. 75.71.201.190 (talk) 13:07, 8 December 2008 (UTC)


DTS and its variants now support Dialnorm, with many DTS encoded Blu-ray discs showing various Dialnorm values such as -4, which makes their levels comparable to Dolby's - all things being equal, of course. Ty Chamberlain (talk) 23:29, 12 October 2012 (UTC)

move[edit]

DTS (sound system)DTS (Company)

This article is about the company, not the sound system. Should be DTS (Company) or similar. Int21h (talk) 07:45, 15 April 2010 (UTC)

DTS Express is missing[edit]

Blu-Ray[edit]

The lack of mention of Blu-Ray really dates this article. Additionally there are many phrases that require the article to be contemporary "Nearly all standalone receivers and many integrated DVD player/receivers manufactured today can decode DTS." In an article full of references to Laser Disks. —Preceding unsigned comment added by 78.105.212.184 (talk) 15:25, 12 June 2010 (UTC)

DVD, primary audio tracks[edit]

There is something wrong in this paragraph: MPEG-1 Layer 2 is a video standard, not an audio standard. Maybe MPEG-1 Layer 3?--Stemby (talk) 17:00, 10 February 2013 (UTC)

Sorry, actually it's correct. I got confused with MPEG-1 Part 2.--Stemby (talk) 18:42, 11 February 2013 (UTC)
