Hairspray DTS HD 7.1 playing DTS 5.1

[GreenMotion]

While popping in Hairspray, and going thru the sound setup, I noticed it said DTS HD Master 7.1. Yet, when hitting "display" on the PS3, it shows DTS 5.1

I know the PS3 is unable to bitstream this and instead converting it to Linear PCM; but I was at least expecting the "display" to report its a DTS HD 7.1 track. So I can only assume my receiver is receiving 5.1 Linear PCM.

I have all output options enabled in the Sound Setup (I have an Onkyo 805), but I also noticed the output options only list 2-channel and 5.1 DTS output. Not even DTS-ES?

The core of a DTS track will never be 7.1
It has to be either DTS 5.1 or DTS:ES 6.1

The dts-MA contains a core DTS track so it will be one that you've already seen on DVD-Video.

[WickyWoo]

Well, it's still better than the DVD version because that's likely half bitrate DTS.

[ryoohki]

The DTS HD and HD MA track include a DTS 1.5mbits 5.1 CORE as B/C

You can off course apply PLIIx to it with PCM (decoded by the PS3) if you receiver can do it... so you'll have 7.1 back..

If you want the 805 to decode the DTS ES, set up the PS3 to output bitstream via optical. Then your 805 will do the rest.

Works like that on the Onkyo 674 too. Watched Dr. Stange (always set to bitstream), and was able to get the DTS ES 7.1 core. Sounded great. Word of advice, better to have the HDMI set to bitstream than PCM. Things like this happen. If you choose a PCM track, the PS3 will output PCM. The only exceptions right now are: dolby TrueHD (must be set to PCM to decode) and DTS HD (cannot decode so send out the legacy core).

GreenMotion is correct about the Hairspray BD playing DTS 5.1 instead of 7.1.

I played the disc on my Pioneer Elite BDP-95FD through my Pioneer Elite VSX-94TXH 7.1 receiver (which decodes DTS-HD Master Audio 7.1) and my Pioneer Elite Pro-150FD plasma display. There's only one small part of the disc that outputs DTS-HD 7.1. That part is the "NEW LINE HOME ENTERTAINMENT" "HIGH DEFINITION" intro at the very beginning of the disc immediately after the "WARNING" message.

The Pioneer Elite receiver indicates DTS 7.1 during the short New Line intro, but it indicates DTS 5.1 through the entire movie.

[Leopold BUTTERS]

while were all here talking about sound, is it better to use the HDMI for audio out or should i use the Digital audio out and put it straight into my reciever?

[WickyWoo]

HDMI

Optical will only give you the core lossy track

[ClaytonMG]

I think there's lots of confussion here...

DTS-ES 6.1 is the most you can get over optical. It's also the most you can get from the core. You will NOT get a true 7.1 core ever. The New Line HD logo is in DTS-ES 6.1, not DTS-HD 7.1 (unless someone with the capabilities can prove that it's actually DTS-HDMA/HR 7.1). So here's the DTS formats (don't think anyone really needs these, but oh well):

DTS 5.1
DTS-ES 6.1 (also could be 5.1 matrixed)
DTS-HD High Resolution (not lossless)
DTS-HD Master Audio (Lossless)

I think people need to start using the HR abriviation after saying DTS-HD for the simple fact that DTS-HD has two seperate kinds of encoding.

[sonicbox]

Correct. There is no 7.1 channel support in normal DTS, HDMI or not. If your receiver says "7.1 channel DTS" is actually being received, it's lying if you if you are using core DTS.

Exactly, or the thing has the Pro-Logic IIx auto engaged (which happens normally on Dolby Surround EX tracks, though I have never heard of a reciever enabling it automatically for DTS tracks, especially ES ones).

[JetJock]

Actually, DTS-HD MA (Master Audio) does support 7.1 discrete audio. The DTS web site has quite a bit of information on DTS-HD MA 7.1.

http://www.dts.com/dts-hd/71-channel...the-action.php

But!!, There are very specific hardware requirements for DTS-HD MA 7.1.

First, the hardware must use HDMI v. 1.3 or 1.3a. This is very important because there are five versions of HDMI: 1.0, 1.1, 1.2, 1.3, and 1.3a. HDMI 1.3/1.3a hardware just started to become available this last summer, and HDMI 1.3/1.3a is required for both DTS-HD MA and Dolby TrueHD.

Second, the BD player must be capable of sending the full DTS-HD MA 7.1 bitstream via HDMI to the receiver, not just the "core" DTS bitstream. The Pioneer Elite BDP-95FD is HDMI 1.3a and capable of sending the full DTS-HD MA 7.1 bitstream via HDMI to the receiver.

Third, the HDMI cable used must have the bandwidth for the full DTS-HD MA 7.1 bitstream plus the 1080p video including the high bit "deep color" if used. I'm using Monster 1000 series HDMI cables.

Forth, the receiver must be able to decode the DTS-HD MA 7.1 bitstream. The Pioneer Elite VSX-94TXH receiver is HDMI 1.3 and is capable of decoding DTS-HD MA 7.1. Further, the Pioneer Elite VSX-94TXH receiver has a channel indicator for each discrete channel of audio signal it receives. It is capable of displaying 5.1, 6.1, and 7.1 signals for both DTS and Dolby bitstreams. The indicators are as follows:

L - Left Front channel
C - Center channel
R - Right Front channel
SL - Left Surround channel
S - Surround channel Mono
SR - Right Surround channel
SBL - Left Back Surround channel (illuminated for 7.1 audio signal)
SB - Back Surround channel (illuminated for 6.1 audio signal)
SBR - Right Back Surround channel (illuminated for 7.1 audio signal)
LFE - Low Frequency Effects channel (illuminated for 5.1, 6.1, and 7.1 audio signals)

Additionally, 3 curved bars on each side of the (((LFE))) indicator will flash when in use.

This brings me back to my original assertion. Using the above equipment, the Hairspray BD claims to be DTS-HD MA 7.1, but only the "NEW LINE HOME ENTERTAINMENT" "HIGH DEFINITION" intro at the very beginning of the disc immediately after the "WARNING" message is actually DTS-HD MA 7.1 while the movie is DTS-HD MA 5.1.

[quetzalcoatl]

Sounds like you need to call New Line. I cannot test the 7.1 since I only have 5.1.

[sonicbox]

As mentioned elsewhere, the New Line intro is DTS ES 6.1 (not Lossless, and it seems some receivers lie and say 7.1), and not DTS-HD MA. So, it seems you are only having problems with the movie's DTS-HD MA audio track.

I did more digging through the owner's manual for the Pioneer Elite VSX-94THX and found out how to get the type of digital audio signal to be displayed in addition to the channel indications. Here's what the receiver says about the sound formats on different parts of the Hairspray BD:

New Line Home Entertainment - High Definition intro:
Receiver Displays "DTS-HD MSTR" with 7.1 channels illuminated.

Main Menu (Play Movie, Special Features, Set Up, Scenes):
Receiver Displays "DTS+Neo:6" with 5.1 channels illuminated.

New Line Cinema intro:
Receiver displays "DTS-HD MSTR" with 5.1 channels illuminated.

Movie:
Receiver displays "DTS-HD MSTR" with 5.1 channels illuminated.

I've tried every possible surround sound mode on the receiver, and the movie always illuminates 5.1 channels even though the disc claims the movie audio is 7.1 channels.

JetJock, Thank you for doing the leg work for me. I'm going to do some reading on this tonight in conjunction with my system.

Funky!!! I thought people were talking about the core track. That one needs some splainin! Do you have any other 7.1 movies you could try out? Not that it would make much of a difference since the New Line logo actually is in 7.1 sound... But yeah... Very odd!

Hairspray is the only BD I've found that claimed to be DTS-HD MA 7.1, so I don't have any other discs to compare it to. I know of two other BD's that will be released soon in DTS-HD MA 7.1. They are:

Pan's Labyrinth - relase date 12-26-07 (Spanish with English subtitles)
Shoot 'Em Up - release date 1-1-08.

Both of these movies are New Line Cinema releases like Hairspray, so they might have the same problem as Hairspray. If anybody finds other BD's or HD-DVD's released in DTS-HD MA 7.1 or Dolby TrueHD 7.1, please let me know. I'd like to try them out.

There seem to be a few more check here.
