POD HD SPDIF Out Copy-Protected ?
by Amon on 2013-01-06 16:09:18

Hi

It is possible that the Pod HD Destop applies a copy-protected SCMS setting to SPDIF ?

Cause my Channel Status of my RME Fireface800 SPDIF Input is showing a copy-protect. If yes Why ????

here is a screenshot of DIGICheck

Cheers

If i check the Roland UA-55 Quad-Capture S/PDIF Out with DIGIcheck it does no show any copy-protection and all my other hardware with S/PDIF Out are not copy-protected.

Why the POD HD ??

Anyone can delete their own posts. I have done it often when I have posted information that I discovered shortly after to be incorrect or irrelevant due to my misunderstanding of the question. That's what likely happened here - the user deleted their own post shortly after making it, for whatever reason.

Sorry - I don't know anything about that. I was just letting you know that there is nothing 'going on in this forum' re: posts being removed.

I believe that the digital audio formatting is compatible with SPDIF inputs but still proprietary....

I don't think this will keep you from copying your digital audio, but just from unlocking the proprietary signal....

i believe that this is because of the way they use it....

for example Line6Link also carries proprietary midi information to the DT amps...

which is likely embedded in the digital signal....

speculation on my part.... but i really don't see how this minor detail that you went to great lengths to demonstrate will stop you from working with your files or in any way deprives you of your absolute rights to the file contents.

i have same strange Problems with the SPDIF coming out from the HD, my Fireface 800 dont really like this Singnal with his TMS on, but i must do same test more to explain it with evidence.

So first i must know why and where for this Copy Protection is ???  it makes no sense in a Hardware like POD, perhaps in a cheap DVD/CD Player, so i tested it with my DVD Players SPDIF Out and no Copy Protection, perhaps its not cheap enough, its a Panasonic,  and all my Hardware with SPDIF Out (TC4000,E4 Ultra,MotifES, UA-55, VS2480,CD/DVDPlayers ...... in the Studio have no Copy Protection in SPDIF Out or somthing like that,  i couldn't find one only the HD.

Whilst it make sense to provide evidence for your problems, what exactly are the problems you are having (you say strange, but Im not sure what you really mean).

Certainly it's something you need to get to the botom of, but I am not sure you need to know"why" the copy protection exists (in any case, "therealzap provided a response that seems pluasible in this connection"), but knowing the why wouldnt help you out.

If you make a loop in the HD and record it 2 times over the the SPDIF Out in your DAW, it wont null, the two Singnals are different. Can somebody proof this or is it only my HD ?

Audio interface is a Fireface800, and if you check the TMS on or off it will be a different, too. I like the Sound without TMS more, it has a bit more Bottom, but this makes no sense.

No other Hardware makes this, only the POD.

But still my question is not answered, Why and where for this Copy Protection is  ?????????????

you still haven't answered the community reply... why does it matter?

is it preventing you from doing something? or is the simple fact that your software is reporting it just eating at you?

because somethings matter in life... and others.... not so much.

SCSM Copy protection is an old leftover from the days of DAT...Once you record wavs, you don't have to worry as those bits are ignored...nothing worry about unless you are recording from the spdif of the POD to a DAT machine...

You dont understand every loop take you record is a diiferent over SPDIF,  there is a Sound different . Is this matter enough and i want to know if it have something to do with this Copy Protection .

What must i do to get a simple answer on my  simple question ?  did you want to see my Pass or driving licence ?

But i understand there is no answer .

cheers

Ok thanks, but why is the same loop you record in the DAW allways a bit different ? it wont to Null in the DAW,  i can  to null with all my other hardware over SPDIF .

first off... this is a user forum... and noone here will know the answer... all you will get here is our best guesses...

if you want an official answer from an official source: http://line6.com/company/contact/

you">http://line6.com/company/contact/">http://line6.com/company/contact/

youare right about one thing... i don't understand.

but hopefully they can ease your mind.

Ok for ones who understand, make a loop with your HD, than record it 2 times in 2 Tracks with your DAW (cubase,Logic...) over SPDIF,  than proof it if this files are the same, so make a to null, one Track phase invert. If you hear nothing everything is Ok, if not the files are not the same and that means every record you make is bit diffrent over SPDIF.



Re: POD HD SPDIF Out Copy-Protected ?
by TheRealZap on 2013-01-09 17:40:11

so basically you are OOPSing a loop and expecting it to be silent?

not sure what practical application this has other than easing your mind... really i just don't get it... but whatever... like i said call line6 if you want some sort of real answer.

the looper is mono...so, while you live recording is stereo when you record it, once you start looping the loop buffer is mono you get a summed version of your tone...

You still dont seem to have reported an actual 'problem' that I can see. If your goal is to acheive a track of silence, just dont plug anything in . ... or perhaps use one of your other interfaces, as you seem to be able to acheive your inverted track home made silence using those.

Seriously though, I really dont understand. Are you really saying that you can route the HD loop out through analog to another interface, then SPDIF to your DAW and produce a track that will invert and sum to null. I'd be somewhat suprised given the need for the analog stage. Alternatively, if you are using a differrent source, then thats not apples and apples.

Furthermore, despite the possible theory that the sound emmited by the looper will be identical each time, I would personally suggest that this would be very very unlikely. Perhaps if you were using no effects and no sims it 'may' be possible? I mean what type of variation are you experiencing.

If you have any genuine concern here (and I am having to be a little artistic here in your favour) then it could be you are saying that the POD does not maintain a consistent tone through SPDIF. If this is at all representative of your concern I would suggest that you post an example of two tonally different takes so we can actually hear and comment upon the difference.

If however you are merely curious regarding the tech involved (which I also suffer from, from time to time) then I would make this clearer and voice your questions accordingly. The reality is, however, if this is your angle, then few here would be able to give you what you seek.

I am a little relieved, however, that you have dropped your SCSM enquiries.

What if you were using gear that did respect the no-copy bit? If you put a stripper inbetween your POD and your recording gear to turn the bit off it'd then technically be a DMCA violation.

It's actually a bit unclear whether recording software that ignores the no-copy bit might technically be an illegal circumvention device too.

So, the question is - why on earth is this bit set in the first place?
