Talk:Dolby TrueHD

Blu-Ray

Can someone who knows enough about Blu-Ray post the Blu-Ray movies which have Dolby TrueHD. ~Michael

Out of date

This article reads like a throwback to the raging debates of the Blu-ray vs HD DVD war. It's HD DVD centric and seems to even lean toward downplaying Blu-ray. Blu-ray won that war some time ago, and HD DVD is a dead format. The article needs to be reorganized to center on the Blu-ray context since that's what readers will generally be here to read about. HD DVD information should still be included in a historical context. I'm thinking of making that edit if no one objects. 24.23.207.45 (talk) 22:44, 19 September 2008 (UTC)

Alright. I did go ahead and make the changes. I haven't made such extensive changes to a wikipedia article before. I hope folks will be pleased enough with the results. I do think it's a strong improvement for an article that was previously both biased and out of date. 24.23.207.45 (talk) 18:48, 23 September 2008 (UTC)

BD vs. HD DVD

Surely it should read mandatory for HD DVD and optional for Blu-ray Disc hardware? (Right now it says media). From what I've just read about Warner's first HD DVD titles, only one of them will have Dolby TrueHD (The Phantom of the Opera, the others will use Dolby Digital Plus). —Locke Cole • t • c 08:08, 29 March 2006 (UTC)

Decoding

If you have or know of a AV Receiver or Surround Sound Processor that can actually decode Dolby TrueHD please post it. Keep in mind that the device must support HDMI 1.3. As of May 2007, the Onkyo TX-SR605/705/805 supported True-HD (raw) over HDMI 1.3. There are others, too.

Long list

Is the long list of titles with this specific audio coding really necessary? Can't we simply delete it? /SvNH 22:26, 6 May 2007 (UTC)

It would be better to create two list articles ie 'List of HD DVD titles with TrueHD' and 'List of Blu-ray titles with TrueHD' John a s 07:10, 13 September 2007 (UTC)

Maximum Number of Channels?

On Panasonic's BD Glossary, they say that TrueHD can "technically" support 32 channels? So is it 14, or 32? Nick 8 04:48, 23 August 2007 (UTC)

It definitely does not support 32, unless you change the spec of course. But if its in relation to BD, thats only speced to 7.1, their just trying to make it sound good, but they exaggerated way too much. --Ray andrew 12:44, 23 August 2007 (UTC)

hdmi 1.1 required for unpacked dolbyhd?

the article says: "HDMI 1.1 (and higher) can transport multichannel PCM-audio, and therefore can transport an unpacked TrueHD audiotrack" but if u read the hdmi 1.0 spec it also can do that. —Preceding unsigned comment added by 82.96.59.131 (talk) 13:54, 10 September 2007 (UTC)

that's not right then, because Spec1.0 is just DVI-D without audio support. Markthemac (talk) 15:22, 5 March 2008 (UTC)

Nope see HDMI --Ray andrew (talk) 21:44, 1 June 2009 (UTC)

TruHD versus TrueHD

I see a lot of new hdtv torrents listed as TruHD720p. Is this Dolby TrueHD? And if so, what media player can play TrueHD? Family Guy Guy (talk) 12:26, 18 March 2009 (UTC)

Transport

"S/PDIF cannot carry Dolby TrueHD due to bandwidth limitations, as S/PDIF is limited to 5.1 channels of compressed discrete audio. When using S/PDIF, a device such as a Blu-ray Disc player will automatically send the Dolby Digital audio." is a misleading statement. It should be mentioned that S/PDIF is capable of 6.1 discrete channels under the DTS-ES Discrete 6.1 (notice only under Discrete format). —Preceding unsigned comment added by 72.68.93.240 (talk) 23:00, 27 May 2009 (UTC)

Mandatory AC3 track for Blu-ray Disc

"Since TrueHD is an optional codec, a separate (primary) AC-3 audiotrack must be present on Blu-ray discs that contain a TrueHD track."

It is unclear what kind of AC-3 track this must be. Is it the same as the TrueHD track? 7.1? 5.1? If someone would add this, it would be clearer. —Preceding unsigned comment added by 77.249.234.22 (talk) 03:19, 30 May 2009 (UTC)

It need not be the same channel format. --Ray andrew (talk) 21:45, 1 June 2009 (UTC)
