"Cinavia"/Verance BluRay audio watermark protection [Archive] - Page 41

I'm betting somebody knows something. I find it rather interesting, that $ony is the only company massively supporting Cinavia. I suspect other companies may be aware of a possible circumvention. Hopeful thinking? Conspiracy theory? Perhaps. But then, perhaps the other companies are being asked to pay a ridiculous sum of money to employ it? One thing's for sure. If ALL the companies were suddenly using it, there would exist an even larger need, to circumvent it. Myself, I don't even give it much thought. None of my devices support detection. Though I do find this "irreversible" protection scheme intriguing.

I don't believe in the no win scenario... :p

From my reading on the matter, the licencing fees that Verance charges are truly extraordinary! Like 10K to 300K, and then per film and per disc charges on top of that. None other than a large studio could afford what they charge! Perhaps I should have taken out shares...

-- RANT BEGIN --

Am I the only one that finds it interesting / disturbing that $ony is the ONLY company that not only makes content (movies/music) but also makes technology (players/recorders). It comes as absolutely no surprise that they are one of the main perpertrators in the DRM scene. Just think back slightly to the '$ony rootkit fiasco'.

I personally will NEVER buy a $ony product. They continually push their own proprietry formats (beta, mini-disc, memorystick, DAT, and the list goes on) and don't allow other manufacturers (with incredibly few exceptions) to make equipment that uses their technology.

I know people who (sadly) only buy $ony because of their reputation in quality. I also have a damn good laugh when they pay top dollar for a system that bugs out with some DRM issue that my cheapie no-name brand cobbled together system works just fine with!

That $ony are right on board with Verance and Cinavia comes as absolutely no surprise.

-- RANT OVER --

What does interest me is rather than removing cinavia from a stream, is actually reading cinavia from a stream. And then being able to add my own 'cinavia' like data to the stream.

Sure, one method of defeating this horrible DRM scheme is to remove it, but another is adding 'scrambling' data to the cinavia stream so the BD (etc) reader can't figure out what it is getting.

There would be other uses as well, like embedding useful information into an audio stream rather than just the DRM crap that studios force upon us mere 'mortals'.

Well, the situation is a bit different, yet you hit the nail in the head.
The consortium has agreed that cinavia will be mandatory. Also the fees are generally "solved" internally.

That means that not only Verance has to gain from this, but also the studios, because this way they prevent a newcomer from entering the club.
Because, in the DVD world, one could optionally implement eg CSS, let alone other protections, ie he was not forced to pay CSS royalties.

Now that is something that I didn't even consider...!

It really does turn the whole bunch of them into one big club. The RIAA & MPAA were bad enough by themselves, now they are making DVD manufacturers join the club!

What we need is an insider to release the tech details so we can have our way with it... remove it, or turn it into something that is actually useful!

Hmmm, my apologies. I didn't realise that. Has anyone done anything with those tech details... apart from DVDranger?

Also, additional apologies for my assertion earlier, Verance charges BD-player makers between 10K and 300K per licence (according to wikipedia), not studios. My suspicion is that the studios have to cough a LOT more than that, I don't think that Verance would settle for only charging for an occasional 'track' encoding, even with the per-disc charges added on top. Certainly not when the studios are rolling in it.

After all, if Verance spent 10 years developing it (wikipedia again), that amount of R&D would not come cheap.

MM
The official sources are the patents Verance filed since 2003 or so. Cinavia cannot be reverse engineered, at least not like it was tried by amateurs. I doubt DVD Ranger would get something out of it in due time, let alone the legal complications that may follow.

The research power (man-hours) was not that problematic, as the algorithms were already known, all of them, Verance took the the unfinished work of SDMI and tested it against a few common methods the "damn pirates" usually employ (like conversion to MP3).

The whole issue is to let the audio unchanged while removing the "noise". And since this is quite impossible now, the only weapon against this is the boycott. The problem with boycott is that no alternative exists - this is the power of monopole.

DVDRanger has released a version of their software that works reasonably well. Not HD level audio, but far better than anything else. There's been a lot of discussion on what it does exactly.

http://club.myce.com/f62/dvd-ranger-releases-cinex-hd-promises-unsurpassed-sound-quality-335484/

His database files do contain full length versions of the movie soundtrack. Mangled, but easily recognized as part of those movies. I just don't see how they are going to survive any legal challenge to distributing copyright protected material.

Ghitulescu

7th March 2014, 09:54

They will survive as AnyDVD does :)

Nevertheless I see a problem in having an online database. First of all, anyone can monitor who's accessing it (and combined with BD-live to identify the legal owners and the pirates - even if the detection is false one can still have problems). Secondly, the provider of the database may be legally forced to close it or the IP might be blocked. A third aspect is that a computer has to have access to internet (I won't repeat why).

7th March 2014, 22:54

DVDRanger system

The "so called database" is purely a collection of scrambled (so they don't look like audio files) AC3 audio files that are NOT Cinavia infected.

These files only contain the middle frequencies (cut off at 4K) and therefore are relatively small.

The process works by replacing the middle frequencies of your original sound track and uses your original track for the upper and lower frequencies.

The result is a very average quality AC3 audio track, (and of course it is AC3 no matter what your original format was).

This is NOT a cure nor is Cinavia cracked in any way.

I'm not defending them with this next statement, BUT, we can't know for CERTAIN how they obtain the mid-range Cinavia free audio. It's entirely possible that they're using their removal process to generate it. I grant you this isn't overly LIKELY, but, since NONE of us know for SURE, we have to at least entertain the possibility that they're generating it instead of ripping it from Cinavia free sources.

That all being said, it's AC3 and not HD audio and therefore not a solution I personally accept.

Hi Samuri

It is possible that they are generating the Watermark Free audio themselves, but if that is the case, I would have thought we would NOT need the "Database", all this could be done on our own PC's running their s/w.

i.e., their s/w running on our PC could strip the middle frequencies from our audio, process it, then mix back.

Obviously, a "pre processed" version does offer a speed advantage, but as Neuron says, very very dodgy legal issues. If I remember correctly, reading the posts, there was an option on their s/w for this, im not sure, but I don't think anybody got it to work.

Also, I totally agree, AC3, plus the distortions in the processed middle frequencies, is NOT acceptable.

They've said they may offer it as a cuda driven process in the future. If they do then you'll be able to process your own titles. Right now they're saying it takes 3 hours per 30 minutes of audio to process. So they created the database with what they call a "first pass". Given that it supports under 20 titles so far and there are 127 titles with Cinavia and growing, well, the math doesn't work out well at present.

lol, Don't be so gullible. DVD ranger hasn't broken anything. They are likely using the old fashion technique, "audio replacement" which was used when Cinavia became a nuisance. mark my words: you will never see manual Cinavia removal with clear quality coming from them.

Who said I was gullible? I never said I believed it one way or the other. I simply repeated what they claim. I have zero intention of purchasing their "solution" regardless of how it works as the end result is not hd audio. Cinavia removal with lost quality is pointless IMO. Avoidance with no loss in quality is far simpler. For the record I'm highly skeptical we'll see them release support for a movie that doesn't already contain a non-cinavia ac3 track. I'll leave it at that.

This is in case you wanna stick to a Cinavia infected machine:
currently a solution to remove cinavia that has become viable for most users is: using Audacity, just extract the audio from the video, run Audacity and load the audio file from the video source then, go to 'effect' go to change pitch you will see percent change enter: negative 13 and simply press 'OK' export to desired audio output and mux to video. :cool: It's totally free.

That's an improvement since the last "efficient" way of removing cinavia required a change in pitch of -14 :)

Rant
First let me start by saying "If Sony wants to Install Cinavia into their Movies so I can't Back them up! Then they should provide a Lifetime Warranty to evryone who purchases their BD's for what ever reason including physical damage. Unit then I will continue to work to find A hack or a fix for Cinavia.
End of Rant

I have been focusiing my efforts on the the firmware of the the standalone Blu-ray players and still am.
Before I was working on something similar to Possible DVD rangers Cinex. I was comparing the DVD audio to the Bluray audio. Then creating a patch. Then running the patch against the Blu-ray audio. Unfortunatley this did not work as it to damaged the audio.
I just got the DVDRanger Database of their Exe's. I found I could you the trial version if I had installed the Exe's. So I tried to do a back up of my disc of Zero Dark 30. First if not mention elsewhere. DVDRanger will only allow for Movie only and will under size the video. Could have been me too but don't think so. It will convert DTS MA to AC3 or DD 5.1 at 640kb/sec.
On the trial version it Places the DVDRanger Logo and Trial version onto the Vidio in the centre for the entire movie. Geat trial you get nothing for your work. However I demux the Audio and Remuxed both My Stream with their Audio. So in short I now have a remuxed Zer0 Dark 30 that is Cinavia free.
Then I started to look at DVDRangers Database. I only own 8 of the 100 that they have released. In the 8, I own the DVD is exactly the same size as the the blu-ray. Minute by minute and no changes between them. They are exactly the same movies. So this got me wondering are the just offerring the DVD audio and remuxing it back into the Blu-ray?
I am waiting for their release of some movies like Total Recall with Colin Farrell which are not exactly the same, scenes have been added and shortened so audio will not sync.
This just my thoughts but may bay some one else can comment on the other 92 releases.

@1bullet: testing of their solution seems to indicate that are just replacing part of the audio with that of a cinavia free source. So they are in a away distributing copyrighted content themselves and not defeated anything. You also lose dts, last time I checked that still couldn't output to surround sound and if they could only Dolby digital not DTS.

My question to them (DVDRanger) is how do you attach to the watermark, when no one but Verance and Sony can even find or see it ,in the in the Audio as they have the expensive tools to see it.
I Challenge DVD ranger Give me your command line tool you are offering future so I can test. If you are not just replacing the Blu-ray Audio with the Clean DVD audio I should be able to tell. I will even buy your Cinex-HD CMD line tool when it becomes available if you are not spoofing people.

Why?

Do you have such a warranty on your car? On other media, like CDs or DVDs? Or even on analogue media, like vinyls? On software, in particular with games, which are the pendants to BD in terms of copyright rights and exceptions?

I don't like your example but I will argue it. All manufatures of cars offer at least a one year of warranty. And it it is bumper to bumper. You are also given the opportunity to purchase a extended warranty. Even in the USA they also have the Lemon Law on cars. So if manufacture sell you somethine with a problem that reoccurs 3 times to can return vehicle. So this is my case on vehicles.

I didn't thinlk my Rant would be the topic now. LOL

But I feel Cinavia is more like going to your local coffee shop.
You want a coffee, you drink it black, but at the Sony coffee shop you get your coffee there way. 3 sugar 3 cream but you don't want it this way . Too bad they bought up most of their commpetion you get it their way or nothing.
So you are now trying to figure out how to get the sugar and cream out and have your black coffee.

I will use this as an example I own the BD + DVD combo movieThe Fighter with Mark Wallburg. The pointers on the orginal disc have issue and on my player the Audio goes blank after 55 minutes. So I now have to choise take BD to end and rewind it. to 10 seconds after and watch it. Or back up a remux of it and it plays perfect. Which my remux does!

Try taking it back to Best Buy. You opened it you own it.
Now I did try contact Paramount, since the Movie did this from the first time I watched it. At least "a piss off "from them would have been nice- no responce. Now this movie has nothing to do wih Sony, but at least I could get a working copy.
With Sony they do not have to play by the lemon laws so take your car and park it forever its not your car anyway.

I think I have more rights with my car at least when I buy it. I own it and other than dealing with the police, I have the rights to change color , wreck it , modify it, my choice. I own this the car and have some rights. Sony and all the other studio's you lease the movie and have to follow their rules or you are a criminal. And its not yours. I am just glad Sony doesn't make cars yet.

I am not saying I support piracy by any means and I know Sony has this as their arguement. They say its their right to stop pirated copies.
However Sony missleads everyone into believing for every pirate copy that watched a dowloaded version of their film they lost a sale. This argument has about as much validity as me blaming a car manufaturers for using cheap steal and is why my invisible paint wont stay on my car.

@Ghitulescu -Using my coffee agumentment so you are now longer a coffee drinker, and thats ok, cause the Son'y coffee shop has to protected there shops.

Now Enough of this.

Has anyone used DVD Ranger with the Internet Blocked?
I will do another rip and convert is no answer in the next few days, or anyhing else to do with Cinavia.

Although this is applicable to audio DVDs (DVD-A), if it works, it might provide some insight regarding the workings of the "Verance"/"Cinavia" watermarking methodology, as well as possibly eliminate the need to perform some testing that has already been done.This, in addition to the 2001 white paper at:

But why he do not compare a DVD audio track with an BD audio track. Doing a reduction on them he will see what Cinavia is. This is more than simple. With some experience in audio processing he will also see the details in Cinavia. And finaly if he select the right movies, he will also find the big bug in Cinavia.

Look at post #333

Read it, do you think it would work.

Well prob not, the marked audio is slowly moving +/- in phase, only slightly but enough to give an output and making "cancellation technique" used to see differences useless.

Also, always remember, the Cinavia watermark is NOT a signal added to the audio, its an alteration of the existing audio, in other words, the signal IS the audio.

People already have the original source WAV files of some movies before and after Cinavia has been applied, so they can see exactly what is different between them...

Sorry, if you have the original files where Cinavia was added to, then you can identify Cinavia with an ease. It is much more complicated if you compare a DVD track with an BD track but with some tools you can cut the tracks so they will fit and you can also compare. Sure it is much work and you have to go through different technological changes of the audio but finaly it is possible. So only why some experts are not able to do this, or do not want to invest this time, it is still possible.

If there's a way to hack it from that, it'll be done (although that was last year that I heard that info, and nothing has come of it that I know of... :cool: )

Won't you be good enough to share "the big bug in Cinavia" with those of us who have unsuccessfully put a great deal of time and effort into attempting to thoroughly and completely resolve it? (Try reading this entire thread, the first post of which was made by me more than four years ago)

Tell me a good reason. We invested more than 12 months in working on this. The first generation of CinEx created bad 2 channel audio. The second generation (again 6 months+) creates high quality ac3.
The first generation was published on source forge as open source. This was removed in case of all this offense against us. So why we should publish the 2 generation?
Fact is, our solution works and the quality is the best you have ever heard on an Cinavia free audio track.

Fact is, even your allegedly 'magic' removal trick will require a re-encoding of the original bit-stream. With DTS-MA/TrueHD that's a big compromize.

Does Cinavia protection only show up when you use an HTIB to play the video file watermarked with it? Consider two situations:

1-I connect an HTPC (using video card HDMI output) to the HTIB HDMI input in bitstream format, so its only function is to decode and play the audio, but not to play the video file itself. The video file (or a BD backup) will be played by a media player software like MPC-HC.

2-I Play this video file in a USB stick on a modern TV/monitor which can send HD audio stream to an HTIB or a receiver.

In either cases, will be Cinavia protection still present? Or only playing a watermarked file with the bultin player from HTIB with Cinavia support will trigger it?

That's how I always figured it will be cracked. In fact, on firmware-level it's actually rather 'trivial.' If I remember correctly reading the specs properly (when it first came out), there's really only one or two bytes (!) that determine the carrier type (to check whether your content is being played on the appropriate device). A simple hook into that check will disable triggering the Cinavia alarm entirely. That's Cinavia's Achilles Heel.

Getting the firmware flashed will be harder, of course. :)

But for all those people who own Blu-ray players that had Cinavia added to them via a firmware update 'after' their players were originally manufactured, there might be a way of removing or disabling it...

Not yet. :) When they do, we're all hopelessly screwed, of course. Or like when Intel decides to add Cinavia to their (motherboard) chipsets.

I'm very curious how people think this is going to work. Since the beginning of Cinavia people have come out of the wood work to claim that it's going to be added to everything from receivers to tv's and hell probably the new moto 360 watch I'm sure. So the receiver detects Cinavia. Then what? Let me guess, mutes the audio right? Except how does the receiver, or any other piece of equipment that isn't the player, determine if it's a copy or an original? The player decrypts the streams sent to the receiver so the aacs encryption that the Cinavia algorithm looks for is long gone at that point. When this fact is pointed out to people they then create wild schemes of how the receiver will then communicate back to the player to ask it nicely if it's an original or not. Which is nice and all but not likely to happen on bluray at this point. The new 4k discs will likely have an all new drm scheme which will likely be an evolution of the current bluray drm. But even then it's likely simply going to require whatever upgraded drm be part of the player spec. There's already receivers and tv's out there that don't include any new drm scheme but do support 4k content.

Less wild than you may think. Or, I should say, as wild as HDCP is a "wild scheme." And Intel really has been toying with the idea of built-in DRM into their chips for quite a while. Not Cinavia, to be clear, but similarly convoluted "wild" handshake schemes that everyone thinks will never occur, but then tend to happen regardless.

So far it hasn't taken place yet. But requiring (hardware) media players out there, like PS3, to do Cinavia checks is no more far-streched than forcing motherboard manufacturers to do the same. And if you have a big bag of money, and buying laws is somehow legal (only in America, LOL), the improbable is always just around the corner.

As you correctly noticed, cinavia can only work at player basis. But the laptops and other things are used as players, not as bypass devices (like the AVRs). It would make sense to insert such detection routines there.

Yes, the Chicken Little claims have been around for quite a while.
It costs money to license Cinavia and doing so would make a product less attractive to consumers so it only makes sense to claim Cinavia might be included in devices such as laptops if you can explain who'd pay for it, why they'd want to pay for it, and how it would be included. Without that, it's nothing but speculation at best.
When it comes to Cinavia in other devices it's the same "all or nothing" principle as it is for Bluray players otherwise what would be the point?

Assuming this is accurate (http://blog.dvdfab.cn/cinavia-protection.html), the number of Bluray releases including Cinavia to date is 175. For DVD it's 15. That's a grand total of 190. A total of 190 in four years. And that doesn't include the titles in the list to which this disclaimer applies. I didn't count them, but a page search found 94 matches for "*".

* for those, in territories where the movie is not released by Warner Bros., Sony Pictures, 20th Century Fox, Universal Studios or Disney, the Blu-ray does not have Cinavia

Cinavia seems like it's pretty much a non-event to date. Nothing more than a bit of an inconvenience for owners of recently purchased Bluray players.

Anyone know.....
These days when you buy a movie on Bluray it often comes in multiple forms. You get a Bluray copy, an Ultraviolet copy, a digital copy, a DVD copy..... how would a system such as Ultaviolet work with Cinavia protected content if all devices could detect Cinavia? I guess you'd need a different watermark for different formats and devices would need to recognise a particular format and allow it to be played, but not others, maybe working in tandem with the copy protection methods already in use (http://en.wikipedia.org/wiki/UltraViolet_%28system%29#Selected_DRM_technologies). I've not really thought about it myself.... it's just something which popped into my head while I was typing.
