DVD-A

[Sol]

So DVD-A has 192K right ... well I just spotted my PS3 has an an optical out!

So ... if I had a 192K DVD-A disc (which I don't) and played it in the PS3, assuming the PS3 passes 192K through it's optical out (I've not confirmed this) took the optical (toslink) into the X-DAC V3 I should get better quaity that a redbook 44.1K CD playing from my Marantz into the X-DAC V3 which is then upsampled (IIRC) to 192K?

Am I missing anything .. can anyone confirm the PS3 192K capability?

DVD-A can do 192K, but more often 96K. Commercial DVD-As normally don't permit digital out.
Neither do SACDs at all. Home made DVD-A using programs such as DVD Solo can export to SPDIF, BUT Optical out is far too slow. I understand that many SPDIFs can't handle 192K either (?). BTW, does PS3 play DVD-A ? I would be surprised if it did, but could be wrong.
Software supplied could be a limiting factor ?

Guess I'll do some checking ... ahhh well! as you say if the DVD-A format doesn't aloow optical out I'm stuffed as the PS3 does not have coax. It does HDMI ... but I doubt there are options there either!

Ahhh well .. worth a muse!

My sons got a PS3 and I keep meaning to try it as a transport, the good thing is they have regular firmware updates, not sure if these are DVD audio compatible or not, must have a browse I think

The picture in 1080p is very impressive on these things!

I double PS3 will support DVD-A as they are into SACD, remember? Anyway, the high rez streaming should be available even if most of the time the disc does not direct output once the tray is closed. This is because once you get into the disc menu there will be choices and clicking into the high rez choice most of the time does output high rez at the optical. I have a Linda Ronstadt - Whats' New album outputing 192 Khz from my Pioneer and perfectly accepted by the optical link at my X-Dac V3. The sound is just glorious. So don't worry about the optical cannot support 192 Khz. Anyway, I had changed my optical to a 15 MB/s when my original 6 MB/s in the X-dac V3 went to heaven last time. The latest optical specs had up the ante to 100 MB/s, fyi.

Jaycar now has a 5V 15MB/S in their new catalogue for around AU$5. Not in stock yet, though. I will also be fitting one.
I have checked quite a few of my DVD-As , and only some of the earliest ones allowed digital out. In some cases, the digital out was downsampled.
My Creative X-FI soundcard , although it can play DVD-As, gives a message with ALL DVD-As that digital output is not permitted.

BTW, I have the same DVD-A, and it is one of the very few that permits digital output. However, I can not confirm that it isn't downsampling.

Ya, changed it since yours also kaput, right? For AUS 5, just get it when the stocks arrived.

The Linda Ronstadt album was outputing at 192 Khz as that's what the display showed for bit rates when I went into it on my Pioneer. My Pioneer has the option whether to downsample or not and I obviously chose the do not downsample option. My music freak friend loaned me the Beatles Love album and it was also outputing at hi rez at the optical though at only 48 Khz 24 bits. The Donald Fagen - Morph The Cat was outputing at 96 KHz whereas another Donald Fagen was outputing at 192 Khz as well. Sorry, I can't remember what's the album name for the last.

Even for Dolby or DTS versions, we can also go into the menu to get the hi rez outputs as the hirez files are already embedded in the Dolby or DTS format.

I am well aware of those settings as I have a Pioneer DV-667A
I think that the Music Industry may have changed the rules and demanded no digital output with DVD-A. See below.

Not all DVD-A Discs are Created Equal
We purchased and examined a fairly good sampling of DVD-A discs. We were quite dismayed to find that DVD-A discs can have built-in copy protection that forces a DVD-A player into a low-resolution down-sampling mode at the digital outputs. When the copy protection is activated, 16-bit, 48-kHz output is usually what results when playing 24-96, or 24-192 kHz material. This disc creation option was provided in response to the music industries demand to prohibit the unauthorized copying and sharing of a DVD-A disc - at its full resolution. Unfortunately, the producers of most DVD-A discs that we examined have chosen to exercise this option.

MORE :
The digital output of a DVD player lacks both high data speeds and copy-protection mechanisms to support DVD-A. Because of this combination of technical and legal concerns, if you connect a DVD-A player using only the digital output, you don’t hear the full quality of DVD-A music. You can only get that by running a six-channel set of analog cables between the DVD-A player and your receiver or preamp.

Ya, last night, I tried another 2 dvd-a from AIX and it outputted 96Khz 24 bits thru the toslink. Fyi.



One was the sampler 3 from AIX









and the other was Dorian Michael

How do you know it output 96/24 via Toslink?. Just because the on screen display says it is 24/96 doesn't mean that it isn't being downsampled for digital output, as the Music industry demands.
Did you export the Toslink output to your PC, and check what the actual resolution was ? Or perhaps you have another method to verify the bitrate and depth of digital out ?
Another explanation is a player that does not conform to the Music Industry's requirements. Whatever, it is not supposed to output full resolution digitally, except via HDMI. That is a licensing requirement.

Oh, I always have my Pioneer to do not downsample. There are usually 2 tracks in those AIX. One is the multichannel "Stage" and "Audience" on one side and there will be a DVD-V with high rez 96 24 bits in stereo on the other side. Even with the mutlichannel ones, the X-Dac V3 will combined them into 2 channel internally. I'm saying this is because there was one dvd-a, which I cannot remember what title, that have completely no output from the digital output and toslink and the X-Dac V3 just went dead silence. However, there was output from the analog rcas. I have not try it with any PC. Perhaps, some members can and will and report back.

Yes, so do I with my Pioneer DV-667A. However it does what the Music Industry has instructed the manufacturers to do with DVD-A as part of the licensing agreement,and to hell with what you and I tell it to do !
