How SACD and Sony encrypt DSD files

The master DSD layer of an SACD is copy protected by some unique encryption methods by Sony.

[@thegrimyeaper]

I remember a CD so well protected that it made it so that my CD player never played a CD again. Brilliant.

[@victormuriel7266]

Always the best Paul.

[@glenncurry3041]

Is the data file disc provided in DoP or just a bit stream?

[@FlashbackArrest]

I hope i can be like you when I become your age. You're always so comfortable. You're awesome, dude.

[@digggerrjones7345]

Have you read any of the OR reviews on Audiogon, highresaudio, etc.?

[@kentonkirkpatrick5225]

Any good reason you don't have a link to your Octave Records catalog? Just wonderin'.

[@doctormidnight]

SACD protection hasn't been useful for 15 years, it's incredibly easy to defeat. Those albums always showed up on Usenet within a few hours of physical copies being available.

I Use old play station to extract mine. Then convert them into files

[@johnmarchington3146]

You mentioned that when you buy an Octave Records SACD you also get a data disc. That might have been true when this video was made but it's not true now - or at least the recent Octave Records' discs I've bought have been just that.

It was the drummer Lars Ulrich for Metallica started it all I though on copyright in front of congress or was that something else?

[@artyfhartie2269]

We all have lots of music files to listen to. Hope the computers can cope.

[@allansh828]

Why can’t we just playback DVD data disc with CD transport?

[@BB..........]

Because the formats and pits are very different. You need a DVD drive.

[@IncognitoChild]

To be fair to Sony, America has consistently had Sony in its crosshairs for a number of its innovations, starting with video tape and home recording in the 70s and then digital audio: DAT and Minidisc via lawsuits from the Recording Industry Association of America in the 80s and 90s. The compromise was to introduce copyright protection. So it's hardly surprising then that they were probably forced to do the same thing with SACD knowing that if they didn't they would be in court once again. What stops you from being prosecuted for the same reasons if you are supplying unprotected copyrighted material? (Genuinely interested to know) 🙂

[@MrHamit64]

o SH word. Yeah when you think of it that way I can see why even the singers hella freeked out. Cause well let's use Avril's Love Sucks as an example. If 1 thinks of it the way you say Paull yeah it's like vril handing us the Fans the raw stems. Hot dam!

[@RobCCTV]

Just wondering: are the drivers in that tower of bass speakers behind Paul connected in series or parallel? If the latter, is the impedance of each speaker much higher such that the overall impedance is 4-8 ohms? Does the same apply to the mid and high range speakers?

[@FOH3663]

Neither series or parallel... It's my understanding each driver is coupled to it's own dedicated amplifier, 1kw per driver. The original was all paralleled, with a wicked demanding load, and a purpose built robust amplifier. Paul's IRS bass towers aren't stock at all. New drivers and amps. New Dayton 12" drivers, and they designed their own multi-amp system.

[@RobCCTV]

@@FOH3663 oh ok. That makes sense. Fanx for your reply.

[@hom2fu]

each speaker have it own amplifier. jump to 3:30 kzbin.info/www/bejne/l52bnnycjNt9nrc

SACD can be ripped using a modified PS3

[@TheActualAltair]

Even with out it, it's quit easy now days

[@ThinkingBetter]

As streaming represents around 85% of all music consumption now and that percentage is getting closer to 100%, the studios are becoming less concerned about allowing master quality as few people will spend the extra time to mess around with illegal copies. The FLAC lossless streaming now available up to 192kHz PCM (e.g. Amazon Music HD) is raw unencrypted to the DAC and it wouldn't be complicated to record it but why bother?

[@TheDanEdwards]

"but why bother?" - because one is traveling, or living somewhere there is no reliable high speed internet?

[@ThinkingBetter]

@@TheDanEdwards Yes, partly true, I have some playlists downloaded on my iPhone for travel purpose but those are downloaded from the music streaming app itself easily for offline listening. But of course agree, those who are not able to get a good internet connection will need to have the music locally. At least in the developed part of the world, I believe near 100% of households can get a solid internet connection nowadays. The internet connection to homes has replaced phone and cable TV connections almost everywhere. Nowadays I get 1Gbps to my house with a fiber optic cable and music streaming in master quality (DSD or PCM equivalent) is not even 1% of the available bandwidth.

[@scottyo64]

Vinyl and CD sales have been climbing not going backwards at this point.

[@ThinkingBetter]

@@scottyo64 True, it's an interesting trend. Streaming is however also increasing. Combined these trends confirm what I said, people are more loyal than ever to pay for music. People made cassette copies until MP3 downloads became a thing starting with Napster; and nowadays people listen to either streaming (everywhere) or the real discs (at home). I used to know many people collecting music on their hard drives, but nowadays it seems to be mostly a thing of the past. Perhaps it's a bit like this, if you seek convenience, streaming wins, and if you seek collectibility, vinyl and CDs win.

[@InsideOfMyOwnMind]

@@ThinkingBetter You would be amazed at how many households in Erica still do not have access to good broadband internet. FYI I do not consider the current iteration of satellite to be true broadband.

[@InsideOfMyOwnMind]

This makes no sense to me. If you can publish a DVD Audio disc that's unencrypted then what good is the encrypted SACD to Sony?

[@pauldavies6037]

I agree DVD audio sounded good to me

[@robinr5787]

Think dvd audio isn't used anymore, or hardly, and was never that popular. Sacd still is. Dvd Audio is pcm?

[@paulstubbs7678]

It has to be Sony encrypted for a SACD player to recognise and play it. The DVD will be a data disk, nothing to do with DVD audio.

[@gmak8052]

sony only cares about encrypting their music to protect the copyrighted music and none of the sony library was and probably still is not released on dvd audio under the sony music publishing.When this started dvd audio was a competitor to sacd .

[@InsideOfMyOwnMind]

@@paulstubbs7678 So as I understand it then, the DSD data itself is not encrypted but the key has to be there to activate the DAC's DSD capability.

[@wilcalint]

Encrypting widely distributed content media is futile. Two examples. Both the Red Book CD back in the early 80's and DVD's in the 90's had password Encrypting. Within 2-weeks of releasing the first CD's the coding was cracked and widely available. Sony's Encrypting of DVD was so good that some of it's own DVD players couldn't play them. But within weeks the coding was cracked and the rest is history. I'll let Paul's comments on DSD alone. The one media that has not been cracked is the Digital Cinema ( early 2000's release ) distribution hard drives. Digital Cinema replaced the reels of 35mm film for the distribution of movies in theaters. It lives today and as far as I know has not been cracked. en.wikipedia.org/wiki/Digital_cinema "Digital cinema refers to adoption of digital technology within the film industry to distribute or project motion pictures as opposed to the historical use of reels of motion picture film, such as 35 mm film". Virtually all movie theaters today use a Digital Cinema media server. The distribution of the drives is the same way reels of 35mm film were distributed. UPS.

[@finscreenname]

I was always taught you cut one board and then use it to copy for the rest. If you just keep using the last board you cut, your measurements will be way off. You just have to copy the original.

[@Gmagee]

I really don't think Sony did it to protect artists, they did it to protect Sony profits.

[@loganxmen3114]

👹

[@duanecook4227]

To protect the musician and 'the master', good one, I got a laugh out of that. Why would an artist ever want anyone to have access to their art. Keep on gatekeeping.

[@NoEgg4u]

@4:40 "At Octave, when you buy one of our SACDs, you also get a DVD data disk that actually does have the unencrypted, unprotected file..." Paul, you left off the noun between "unprotected" and "file". Are you saying that that DVD data disk's file is an "unprotected DSD file"? That unprotected file is of what format? I think that you mean DSD. But I would rather not assume. Assuming is how things go wrong and misinformation spreads. Thank you.

[@BB..........]

It's a DVD data disc with DSD files on it. I thought he was very clear what he was saying.

[@NoEgg4u]

@@BB.......... He implied along those lines. He had a lot to say on the subject. But he never came right out and stated it plainly. If you feel that he did, then please provide the timestamp and / or his quote.

[@BB..........]

@@NoEgg4u 4:39

[@NoEgg4u]

@@BB.......... What Paul said @4:39 is ambiguous. He said that when you buy one of his SACDs, you "also get" a DVD data disk. He did not state that that additional disk contains DSD data. It is common for people to state things where the listener connects dots, and that is how the listener gets burned. Perhaps those dots are what is being suggested. But that is not the same as plainly stating that the DVD disk contains DSD data. Why, if when you buy one of his SACDs would he give you another disk -- a DVD disk? The SACD disk has DSD on it. So why the additional DVD disk? If the DVD disk also has DSD on it, then why the SACD disk? Why have two disks? Why have one with encryption and one without encryption, that both contain DSD data? Paul never said that the DVD disk has DSD data on it. He said only that the DVD disk does not have encryption. Until he states that the DVD disk also contains DSD data, I will not conclude that the DVD disk had DSD data.

[@BB..........]

@@NoEgg4u Work on your listening comprehension. Back up 30 seconds or a minute earlier, but this time actually pay attention to what he's saying. It's 100% clear he's talking about DSD files on a DVD data disc.

You might have a fighting chance against Sony, they are $2 trillion in debt.
