article published on 3 March, 2010
FileShareFreak has a very interesting report out today about Cinavia DRM, which is a new audio watermarking technology that takes aim at pirates, and those trying to playback movie downloads via their PlayStation 3s.
The site says the watermarking works by "comparing the source of the audio to the format in which a movie was released (ie theatrical or commercial disc), and if the watermarked ... [ read the full article ]

To be honest, simply encoding the audio should remove such a watermark... if I'm not mistaken the mp3 codec for example removes inaudible sound ranges as part of its compression.

How so? If its ripped to a digital format (MP4, AVI, ect...) and put on the HDD it should still work.

Couldn't you just make sure you disconnect from the internet on your ps3 before you try to play whatever file you want to watch?

I have no real desire to download The Wolfman, but I was reading on Cinavia's website and what really concerns me is that they want to put this new audio watermark on future DVDs and Blu Ray discs. Right now I have an upconversion DVD player, but I would like to buy a Blu Ray player in the near future, and apparently ALL of the new models will have this crap built in. Guess I'll have to look for an older model on ebay. I looked at the Cinavia list of "integrated product manufacturers", but how on earth do you know if a certain Blu Ray model has this DRM or not? Damn, I hope somebody finds an easy fix for this, but if it's already embedded into the audio, I don't see how AnyDVD is going to be able to do anything about it.

Whatever contrived method they use to prevent you from making a back up it will be defeated untill everyone has a barcode on their forehead....

If you make a "back-up" of something, it means it you have the original, which in turn means you can play it;if you can play it, you can crack it/record it/convert it.

So here's what I'm wondering with regard to Blu Ray players. Say you buy a slightly older model Blu Ray player - for instance, a refurbished Samsung BD-P1500. Assuming that it doesn't automatically come with this new little Cinavia detector programmed into it, would it be safe to download the player's firmware updates? Would the Cinavia detector be part of a firmware update, or is that something that would have to already be installed into the player's hardware? Any guesses on this?

no dude.. theres a sound pattern embedded into the audio.. that triggers the whole player to mute itself.. everyone on this site said stay away from blu ray and no one listened.

Yeah, lxfactor, because had HD-DVD won the format war this kind of technology would NEVER have been implemented. And EVERYONE on this site said 'stay away from blu ray'? What colour-tinted glasses have you been reading through?

AnyDVD HD will probably find a way around this. I hope.

as sony is the fore runner of DRM and the RIAA, MPAA its not a surprise that their PS3 & Blu-Ray players will block anything not fitting Sony's lockdown of all media, its probably best to avoid all sony products as purchasing anything from them gives them more funds to be anti consumer with.
sony made billions from the VCR market after changing the law now they have made their fortune and have a vested interest in the movie industry they now back track & try to lock down content.
i wonder if home movies will in the future need authoring or a purchased license from sony for us to be able to watch content we create?

Here is what I read somewhere. Haven't confirmed, but would be funny if it works.
Quote:
Fast Forward (1.5 speed) a couple of seconds past the Cinavia message (before you get the message). PS3 cant pick up the protection code in the audio at anything other than normal speed.
*CONFIRMED by myself. This works. Nice try Cinavia.

Does that mean that playback at any speed other than normal would make the encryption be undetectable?with VLC for example you can increase/decrease playback speeds in increments of 10%, which can be barely noticeable.
Does that mean it would work if re-encoding the audio/video to a different frame rate?

No Dude this has nothing to do with BD but will be added to BD & DVD your comment doesn't hold water. If HD-DVD was still a float it would be implemented there as well.
Hopefully AnyDVD will get their paws on the water mark encryption.
How about HDCP anyone busted that one yet?

So does anyone here with a PS3 know when this Cinavia crap was put into the PS3? I'm assuming it was bundled with a recent firmware update. Just a guess.
As for AnyDVD, don't get me wrong, I love Slysoft and I sure hope to hell that they find a fairly easy fix for this, but if it's already embedded into the audio stream, I just don't see how they'd be able to remove that.
So, in the inevitable event that they eventually start putting this new watermark into DVDs and Blu Ray discs (which you know they will), it seems there are only two options - A, figure out a way to bypass the encryption on the disc itself (ala AnyDVD HD), or B, try the extremely difficult task of trying to hack the Blu Ray player (depending on the model). Or, if you have an older Blu Ray player, don't download any firmware updates and hope to hell that it keeps on working properly. I'm going to be extremely curious to see what Slysoft's view on this is.

Actually you only have to do it for a few seconds then switch back to normal. I tried it on my ps3. First I played it normally and it gave me the Cinavia Error, then I plyed the beginning 20 seconds or so in 1.5 speed then switched back to normal and the entire movie played fine.

I spoke too soon. It worked once, but it seems to be getting me now. As long as I keep it at 1.5 it works fine, but now it seems to be popping pu the error after about 30 seconds of play now.
Not sure why. So maybe they did get it. But it will be circumvented soon enough. Will have to try it out on my xbox.

Try re-encoding a portion of the video file, 10 minutes or so,maybe to a different frame rate, and see if it makes a difference.

Pretty soon there's gonna be more DRM then CONTENT on these disks!
A BD will be 10gigs of low quality, poorly made movie and the rest of the disk is filled with various protection schemes! LOL
I predict a very strong market in BD firmware hacks!

The 360 doesn't have a Blu-Ray player,I think that's where the DRm is embedded, in the player's firmware.
