At the 123rd AES Convention this year, DTS, Inc. (NASDAQ:DTSI) will demonstrate the newly released version of the DTS-HD Master Audio Suite (MAS), the DTS-HD MAS V. 1.5, which officially shipped for Mac-Intel worldwide this fall. Exhibiting at Booth #354 at the Jacob Javits Convention Center in New York City October 5-9, 2007, DTS representatives will provide ongoing training at the booth for show attendees on the new capabilities of the DTS-HD MAS V.1.5.

One of the key new features of DTS-HD MAS V.1.5 includes support for secondary audio DTS Express encoding for Blu-ray Disc, which allows users to dynamically change volume of primary audio for use in picture-in-picture, director commentaries and other interactive features. These added functions support the new generation Profile 1.1 Blu-ray Disc players, which support simultaneous mixing of two audio streams.

Introduced at the 121st AES convention last year, the DTS-HD MAS is a complete software solution designed for the preparation of audio streams for next generation optical disc formats, Blu-ray Disc and HD DVD. It encodes bit streams in the following formats: DTS-HD Master Audio, DTS-HD High Resolution, DTS 96/24, DTS-ES 6.1, DTS Digital Surround and DTS Express. The DTS-HD MAS is also applicable to DVD-V and Surround Music CDs.

"DTS is proud to support the creative community with such an advanced and flexible toolset for the next generation optical disc formats," said Brian Towne, Senior Vice President and General Manager, Consumer Division, at DTS. "Our goal for the DTS-HD Master Audio Suite is to continue to provide the best possible encoding capabilities to facilitate the highest quality content as equipment and technology evolves."

At AES, DTS will also showcase a 7.1-channel DTS-HD encoding and playback system as well as some of the latest next generation HD DVD and Blu-ray Disc consumer players from Toshiba and Samsung, connected to a DTS-HD Master Audio compatible A/V receiver.

In addition to the ongoing demonstrations and trainings at the DTS booth, DTS representatives will present the following tutorial: -0-
Tutorial T3 - "7.1 Mixes for Blu-ray and HD DVD: Workflow from Mix to Encode" Friday, October 5th 3:00 pm - 5:00 pm Presenters: Ronny Katz, DTS, Inc. / Jeff Levison, DTS, Inc. Consultant/Levison Audio


About DTS-HD Master Audio(TM)

DTS-HD Master Audio delivers sound that is bit-for-bit identical to the studio master. It can deliver audio at variable bit rates which are significantly higher than standard DVDs. DTS-HD Master Audio can provide up to 7.1 audio channels at a 96k sampling frequency / 24-bit depth or 5.1 audio channels at 192 kHz that are identical to the original master. The DTS-HD Master Audio bit stream also contains the DTS 1.5 Mbps core for backwards compatibility with existing DTS-enabled home theater systems, and delivery of 5.1 channels of sound at twice the resolution found on most standard DVDs. ...........

The thing that immediately springs to mind will be the ability to export the bitstream to a receiver and still retain advanced functionality like secondary audio. The downside is yet another generation of amplifiers to cope with this.

Good work DTS but your timing is ever so just a bit late. Although maybe Fox really did have their reasons for sticking with DTS.

Quote "DTS-HD Master Audio delivers sound that is bit-for-bit identical to the studio master. "

That sounds good.

you have -got- be be kidding me... Dts-Lossles+

Oy, I just spent an hour yesterday explaining to a friend the politics of TrueHD vs DTS-HD MD vs PCM, what's involved in playing them back from HD DVD and BD, and that the new Onkyo would play nice with bitstream, and could be a solution for his one cable-per-player needs.

God love HT...:)

Interesting to note that DTS Express is a Blu-ray exclusive feature. I wonder why the same feature wasn't provided for HD DVD?

That's ALL we need is more changing the standards while they are already on the market.

We're only just NOW starting to see AVR receivers that can EVEN decode DTS MA, and now we have DTS Express 1.15 for stream mixing???

So pretty much all the new AVRs on the market, that FINALLY got DTS MA, will not be DTS Express 1.15 capable, to mix these streams. Talk about fixing a problem that wasn't a problem... :rolleyes: Who's idea was THIS one? Bluray's? ...what a surprise. So BD owners now get to wait another year for the NEXT generation of AVRs...

PS. I love seeing this continuous improvement for Blu-ray.

Interesting to note that DTS Express is a Blu-ray exclusive feature. I wonder why the same feature wasn't provided for HD DVD?Actually, there is no reason why HD DVD players would not be able to implement this down the road either. I note that there are no players from either side that have it now.

If an HD DVD player chose to decode a TrueHD track and encode to DTS Express, with the menu noises, then it could easily be produced. The extra hardware would just raise the cost, of course, and force the requirement of even newer and more expensive AVRs. I realize this works in favour of what some manufacturers WANT, of course, but it causes more consumer confusion at EXACTLY the wrong time, for a feature that I'm very DUBIOUS is even needed...

[minor rant]
My complaint, is that we're changing the specs on the fly again, and will be forever upgrading the AVRs and players DURING the adoption phase - and these changes will SLOW the consumer adoption GREATLY.

Can't we just stop messing with the specs FOR A YEAR, at LEAST, until the mass market has gotten some confidence??

Your post is speculation, as all ways.

According to that statement, the mixing and volume would be controlled by the player so the receiver does not matter.

Wow, it says that it is part of the 1.1 Blu Ray profile, which supports mixing of simultaneous bitstreams.

Your post is speculation, as all ways.DTS Express is NOT part of the BD 1.1 specification.

Mixing multiple audio signals IS, *just* like all HD DVD players already do.

Please get your facts straight before attempting a take-down... ;)
According to that statement, the mixing and volume would be controlled by the player....what it *doesn't* say, and what you appear not to have thought ahead on, is that any player will require additional hardware beyond what is required for basic DTS MA decoding, to perform DTS Express mixing. The mixing levels are determined by the software in the players, the re-coding to Express-compliant DTS MA streams is not.

It will also require changes to existing AVR designs.

I am not attempting a "take-down" you seem to do that a lot yourself lately.:D

The article states that the 1.1 profile players enable bitstream audio mixing, which would be handled by the player. If the processor is going to decode the mixed bitstream, why would you need to change the processor spces???

Neither one of us know how it will be handled so this argument is pointless. You getting on here to "slam" Blu Ray every second is getting really old. For everyone, probably even hd dvd supporters.

This is nothing new.

However, just because a player does audio mixing, does NOT mean that it can produce a DTS Express bitstream to an AVR. That requires additional hardware and is *NOT* part of the BD 1.1 spec.

(enter our favourite semi-insider, stage left, to confuse this now...) :p

Hmm, looks almost identical to the PR issued last May! Guess it got delayed a bit.

Personally, I don't care if it is "exclusive" to Blu Ray or not. I NEVER stated that, though the article doesn't mention your beloved hd dvd at all. Personally I couldn't give two #$(!Q about this feature. Your "agenda" is just getting old. I don't go around blasting hd dvd every time I can think of something clever.

Rant:off back on topic.

Can you please provide some proof that DTS express has to be handled by the processor? Maybe all control is taken care of in the player??? Have you ever thought of that??

The article quoted does also mention the HD DVD format. I think what is interesting is that for in-player-decode the PiP commentary audio versus main feature audio levels can be controlled by the user. I've noticed main feature audio levels automatically reduced and later restored (HDi author up/down level control?) when watching PiP on things like the Matrix. Seems OK to me that if I'm watching PiP director commentary that the HDi authors lower the main feature sound levels as needed (in their opinion). ;) Interesting that BD with profile 1.1 might have user control over this. Could this be also allowed/enabled in HD DVD with some extra HDi code? Is it really needed?

Seems to have nothing to do with HDMI 1.3 transport of raw bitstream to an AVR.

Bobgpsr,

Sorry I didn't see the hd dvd comment.

But I agree with your assessment.

I personally wouldn't mind seeing more DTS support across both formats. If nothing else, it'll help keep Dolby on its toes.

Why not just out put as PCM? It's what all HDDVD players can currently do and works very well when mixing multiple tracks. It's also lossless, and is supported by a very wide range of hardware.

Evlover - thanks for those links - Sounds like DTS-Express is exactly what the Toshiba A35 is doing currently.

I think I'd prefer a format that used the best quality decoder to the format that you're saying uses the least capable.

Actually, those are codecs. I wouldn't be too surprised if the newer DTS-HD MA capable AVRs could already decode all the DTS codecs, I just wish we could get player support for more than DTS core so I can keep using my old non-HDMI AVR for a little while longer.

I'm not sure what you mean by that last sentence, but I'm also unclear about what gooki meant about the A35.

I think I'd prefer a format that used the best quality decoder to the format that you're saying uses the least capable.

I think you miss understand what the A35 does, and what the press release states.

The Toshiba A35 will give you unprocessed DTS-HD-MA tracks via bitstream to your receiver when playing a movie with a DTS-HD-MA track. Once you engage advanced features that require mixing channels the player mixes in the PCM domain (allowing internal player volume control - like the accouncement) then outputs full bitrate DTS (1.5mbit), all the while not requiring new receiver.

The press reless semms to state similar workings except the output is DTS-Express instead of full bitrate DTS (1.5mbit) that the HDDVD folk get to enjoy when using advanced features that require audio mixing and bitsteam output of a DTS-HD source. But in both cases, neither solutions seem to provide an advantage over outputting a PCM signal. Altough the HDDVD players will do the PCM route if it can internally decode the source audio DTS, DD+ DD-TrueHD, PCM.

DTS Express is NOT part of the BD 1.1 specification.

RDJAM - sorry man. Not attempting a "take down" but your "facts" are completely off.


1. DTS Express, a.k.a DTS-HD LBR, is mandatory as part of BD 1.1 profile players.

2. Post mixing of primary and secondary audio, regardless of Dolby, DTS or PCM, audio is transcoded to Dolby or DTS for spdif compatibility and also sent out via HDMI.

3. What the above means is DTS Express is decoded in the player - and that no additional AVR hardware is required.

4. Also, DTS express is not exclusive to Blu-ray disc. It also works in the stereo case within HD DVD players.
