Dolby TrueHD and DTS-HD Master on HTPC?

Cyberlink/Intervideo plays back TrueHD and DTS HD if you choose 6 channel analog under the software player settings and 6 channel anaolog out of your sound card...


its just like playing DVD AUDIO in HTPC.. so make sure u have a 6 channel analog connection from sound card to reciever...


i have played several of my HD DVD movies this way with Dolby TruHD and it sounds great....


WB HD DVD have HD DVD with 640kbps Dolby plus and TruHD titles have around 1.5mbps to 3mbps .... it is playback as LOSSLESS MLP


Universal HD DVD have Dolby Plus @ 1.5mbps ...

No.

Analog outputs and Linear PCM over HDMI are both available depending upon your hardware.


Some standalone players like the Toshiba HD-series also offer the option of re-encoding the new formats as 5.1 Dolby Digital or DTS over SPDIF for compatibility with older receivers. This compromise involves losing two channels if the source is 7.1 discrete, plus of course the degradation of re-encoding lossless formats in Dolby or DTS lossy format.

Not useless if you select analog inputs. However many 7.1 receivers derive the additional surround channels from a matrix decoder, and the analog inputs are 5.1 channels. Therefore the sound is compromised by two less surround channels if the soundtrack is 7.1 discrete.

I'm not familiar with that receiver but I have a Denon less than a year old. I'm not anxious to replace it. However the practice of decoding in the player allows new encoding schemes to be released in the future without any obsolescence of A/V receivers as long as the player outputs Linear PCM over HDMI.

No. Downconverted, perhaps, but in that case you're not really TrueHD/DTS-HS anymore.

If they can accept six-channel analog, they should not be "useless", but they won't be able to get digital lossless sound. A lossy downconversion will be available.

All of us (myself included) who don't have a receiver which accepts PCM over HDMI are in the same boat. My temporary solution is to use the analog inputs, but if I find it too noisy I'll go with the lossy SPDIF instead.



Edit: I see that Gary already answered, and with more detail.

I feel confident that only two likely scenarios will occur:

1. HD-DVD and BR flops major and ends up like SACD/DVD-A. Apple/iTunes dominate movie sales by IP


2. Some clever guy hack AACS. Or Windows xp/vista drivers. Or something else.


Systems that prohibit users from simple and high-quality experience are typically either DOA or hacked. No one believes otherwise except perhaps a few Hollywood execs lured by the DRM mafia.

I know I am bumping a thread that is over a year old, but I think it serves a good point here: to my knowledge, there is still no way to get DD True HD or DTS lossless on an HTPC. PowerDVD downsamples everything before sending it out, whether you use analog outs on your HTPC's soundcard, or send a digital signal to your receiver.


What an insult. I tend to think knutinh will be proven correct; this DRM crap is killing honest users, while every single movie is pirated months before it's even released on DVD or blu-ray! Other than amazon selling DRM-free mp3s (and apple doing the same but to a limited extent), the A/V industry is truly shooting itself in the foot.


Beyond that, does anyone have any updates on this issue? I know all of us in the HTPC section would love a solution here.

The reason there's been no update is because there are two dozen active threads on this issue and people keep starting new ones. If you take a quick glance you'll see the current state of this issue in many threads.


As of today:



1) Asus Xonar HDAV card is expected to be the first true bitstreaming solution for an HTPC, since it's due any time now, and will come with a special build of Arcsoft TMT. At $200-$300+ pricepoint it will be too expensive for many people that want a low cost HTPC, and many people will just deal with downsampled LPCM while hoping for a PAP solution for their motherboard vendor. Some may never get that, or at least until Windows 7.


2) Intel G45 board is right about to ship (this week or next) and it has PAP built-into chipset by Intel. It's expected that Intel will partner with one of the Bluray software player companies to complete the PAP solution to allow for bitstreaming without the need for separate sound card. Nothing official has been announced yet.


3) Auzen card is going to come out Q408 and will bitstream together with a special build of PowerDVD.


There ya go.

Thanks for clearing that up. But about the software side of things? Seeing as how blu-ray watchers have like two options for their HTPC's, many of us are stuck with powerdvd. I've read on this site that PowerDVD down samples the new HD soundstreams - are you saying that with the new Xonar chipset, powerdvd WON'T do this?


Also, I know that traditional COAX and Optical built for S/PDIF cannot handle the HD uncompressed soundstream, whereas HDMI can. So of course, conceivably PowerDVD could send the uncompressed soundtream out of HDMI, and so long as you have a receiver that accepts it, you've got yourself HD audio.


What about on the analog end of the spectrum? For instance, I have an HT Omega Claro+ that has pretty good OPAMPS and, in general solid analog output. I would be perefectly happy if PowerDVD were to use the soundcard to perform the DAC on the uncompressed digital soundstream - so long as I go from Uncompressed Digital->Analog (and not Uncompressed Digital->Compressed Digital->Analog), I am happy.


So what I am most concerned with is: is it possible that Power DVD will eventually support uncompressed audio such that an HT Omega Claro+ or similarly capable 24-bit/7.1 channel DAC-equipped sound card could then output analog directly from the PC by the Uncompressed Digital->Analog (and not Uncompressed Digital->Compressed Digital->Analog)?


Is there some DRM limitation on on sending Uncompressed Digital->Analog directly out of a PC sound card?


Thanks for your help.
