    Hi All,

    I wonder if anyone can shed some light on a sampling rate query?

    The DVD disc of Neil Young's Greatest Hits 2 disc set shows up on my FLR as 96KHz but only 48 KHz on both my DPA32 and AV32 displays.

    According to the Reprise records website it seems as if it should be 96KHz.

    Am I missing something - like a brain? Or is there something else going on here?

    Thanks in advance

    Martin

    Is it DVD-Video? Spec says it is 48kHz...... DTS 24/96? Any DVD-Audio disk would be analogue if 96kHz, I assume you feed the AV via SPDIF?
    I'll wager the flag is set wrong on the disk at authoring stage?

    Hi Graham,

    Reprise are calling it "Super Saturated DVD Stereo" :) . On their website they strongly IMPLY that it's 24/96. If it wasn't for that I would have assumed that it was a flagging error. As you said that is the most likely explanation.

    The disc is variously described as Picture format: NTSC All Region, DVD V, Hi-Def. Disc format: DVD-9. Linear PCM and DD (on videos?).

    No big deal either way I guess, I just wondered if anyone had come across it or knew why it shows up as 96kHz on player but 48 kHz on decoder. It comes with the standard CD version too. I'll have to compare.

    Thanks for input.

    You do get PCM on DVD-Video disks (fleetwood Mac, the Dance for instance and Dave Gilmour), it is only two channel though......
    So........ I don't suppose your AV is set to make two channel multichannel and therefore limit it to 48kHz??????? try Direct + sub mode I suppose?

    I'd also take issue with "hi-def", it isn't unless someone calls 720x480 hi def, I wouldn't.......

    I agree that's not my idea of hi def either :laugh:

    Tried the AV32 on direct but as I expected it stays as 48 kHz. And the FLR stays on 96 kHz. Where's my missing 48kHz??? :rotfl:

    It's all marketing I guess. But implying 96 kHz when it's not is a bit naughty. I may e mail them. For all the good it'll do.

    Thanks

    Thing is I would have thought that the DVD32FLR is just reporting what is going down the bitstream just like the AV32R just reports what is coming in.....

    is it not possible that the disk has 24/96 or whatever coming off it but the DVD32 is downmixing to 48KHz due some kind of copy protection system restriction? I know some other DVD players, like a Toshiba I had, do this when they output 48KHz from 96KHz streams.

    My DVD32R outputs DTS 24/96 via SPDIF no problem. Copy protection is another idea I suppose though. 24/96 PCM stereo dos sound as if what is coming off the disk but if any DVD player must downsample it due to copy rules what is the point?
    Come on Steve/John, whats happening here?

    Hi Chaps,

    If the linear PCM track on the DVD is marked as copy protected then unfortunately a DVD player (if it sticks to the DVD forum rules) has to downsample the audio to 48kHz on the S/PDIF digital out. It can however (if the chipset/architecture supports it) drive its internal DAC's at 96K, but as the DVD32 is a transport that posibility is not an option.

    imho a silly rule as anyone who wants to copy a DVD will stick it in their PC and copy the whole thing, rather than try and record the audio only from the digitial out of their player.

    So, no point then, just marketing......... :thumbsdow What is the point in having a 24/96 PCM track if they turn on the CP flag so no-one can hear it.... As Steve says, bung the dammed thing in your PC use DVD decrypter, strip out all the bits you don't want (DVDshrink etc.) including the dreaded copy protecion and burn the resulting file to a DVD-R, hey presto 24/96 PCM! Of course leavinng it all on a file server and using an HTPC with a neat menu system does save getting off the armchair to change disks...... :cool:

    Thanks Guys,

    Very interesting. From a purely acedemic perspective of course. :thumbsup:

    And very frustrating that the people it inconveniences the most are those who are most likely to value the potential better quality sound ie those with higher end transport/DAC setups!

    Thanks again.

    Hi,

    Great. It worked just fine. :clap: I will now destroy the back-up that I made so as not to become a pirate. At least I know that my TAG equipment is working OK.

    It is a pity about the need to downsample to 48kHz. Now that TAG no longer exists as such, it's a wonder that someone clever hasn't re-written the software. Probably not enough demand. Maybe not possible. Maybe not do-able easily.

    Before I scrap my back-up I will have a listen and compare the CD version vs DVD (at 48kHz) vs back-up DVD. Again purely for academic interest. Mind you, with the cold I have at the moment I'm not sure that I could hear any differences anyway

    Hi Graham,

    It doesnt take alot to confuse me on techie issues and yes, I am again confused :confused:

    SPDIF?? Is that Optical??? The reason I ask is that I link via Coaxil fro DVD to 32r. Via this connection is then not possible to hear dts 24/96??

    Sorry for the simple questions.............as my signature states "you lives and learns!!)

    Many Thanks

    very unlikely (custom bloodhounds sniff well for pirated disks) but we can give it a try :D

    Good morning Mr. Yakimoto,

    if I remember well SPDIF stands for Sony Panasonic Digital Interface. It identifies the digital COAXIAL interface which is present on all the drivers and CD readers.

    It seems that in order to protect the intellectual property (e.g. avoid all high frequency reconding from digital media to digital media), all the formats encoded at a frequency higher than 48kHz must be downsampled at 48kHz on the SPDIF and TOSLINK (Toshiba link alias optical connection) interfaces.

    Remember : there is no stupid questions, only stupid answers...

    Regards,
    Lenny

    Hiya.
    Right, SPDIF stands for SonyPhilipsDigitalInterFace, this has a number of ways it can be transferred but in your case it goes via Optical TosLink or RCA (Co-ax) phono.

    The DTS 24/96 bitstream goes via this link, I would always use the RCA co-ax version of connection as opinion varies on if the optical TosLink is bandwidth lmited...... This DTS 24/96 will get to your AV32R DP or AV192R.
    What we were talking about here was PCM (Pulse Code Modulated) 24/96 which apparently cannot be transferred digitally only via an analogue stage for copy protection reasons which you have probably guessed by now are so easy to navigate round it makes the whole issue rather pointless and just a hinderence to those that obey the rules......
