Cinavia DRM Embedded into Blu-ray and PS3s

Cinavia DRM Embedded into Blu-ray and PS3s

Even if you’ve never heard of Cinavia, you probably will soon, especially if you are used to downloading pirated movies and playing them back through a PS3 or on a Blu-ray player. Cinavia is a new DRM technology using audio watermarking which is embedded into the audio stream of a movie. It works by comparing the audio source to the format of the movie release (either commercial or theatrical disc), and in case of the watermarked source detecting a difference, the movie will not play at all or play mute. There have already been two hit movies on peer-to-peer network containing Cinavia DRM: they are CAM or TS versions of Shutter Island and The Wolfman.

How does it work? Let’s see an example. If the movie was “camcorded” using a ‘line’ audio source (that from a headphone jack, not like recording the ‘crowd’), then the watermark in the ‘line’ will look for its match – which is, in this case, a theatrical source. As you can guess, a CAM or TS ‘line’ audio won’t match the original format, and so Cinavia will restrict playback of the movie or block it at all.

In simple words, movies that are protected by this technology have some inaudible codes being embedded by the copyright holder in audio tracks indicating how and where they’re allowed to be played. So if the movies are released to theaters and they have a Cinavia code, it indicates that they may be played back only on the professional projection equipment.

So far, the Cinavia DRM technology is only introduced into Blu-ray players, including PS3s, thus it doesn’t affect any players not having Cinavia detectors (including DVD players, PC, HD Media Centers and older model BD players). It means that if you download a movie containing the audio watermark, it will need a compliant hardware to recognize the watermark and block playback.

So it looks like Cinavia technology won’t have any considerable impact on piracy. Those users who earlier streamed to a PS3 or burned to BD-R media can simply choose any alternative way to view movies; so this will be just more about inconvenience than a deterrence. Not much will change unless Cinavia embeds it into DivX-compatible DVD players or finds any other way to get it onto PCs. But even if they will, there for sure will be reverse engineers trying to crack the technology – this watermark wouldn’t be a very difficult target.

jezuitx avatarKarakurachow let's not pretend that people that pirate are doing something noble. Most entertainment is created to make money. People don't get into the entertainment field just to put out free ideas for everyone to take (they have to make money to live too you know). While you might think the profits these people make on DVDs and movies to be obscene please realize that these profits are used to employee millions of people.

menahunie avatarAs the writer states all this will do is cause problems even for a person who buys a Blu-Ray Disk; remember when people went out and bought a blu-ray drive for their PC?
I did and the first thing I got was a pop-up telling me my monitor and other equip wasn't compliant - WTF it was a brand NEW SYSTEM...
Took a FULL day of coding and got it to work fine; the result when I compared it to DVD and HD DVD NOT MUCH. You my own opinion is blu-ray doesn't do squat unless your running a huge screen THEN you will see a difference..
As for this new stupidity ; nothing, it will only stop the AOL'ers....
It will not take long before the "watermark" keys are found in the audio and filters setup in "backup" software to take it out.
The thing is and most of us know like the Sony SecrROM; is it is a ROOTKIT installer.
These DRM copyright software used installs rootkits into a pc; it is used allot on games and other type of software.

No avatarStep 1
To use this guide you’ll need to install two software applications. Both of them
are free and among the most popular movie and audio editing programs for
the Windows platform.
Part A
The first application you’ll need is Audacity - An excellent and easy audio
editing software. It’s compatible with Windows XP, Vista and Windows 7.
Download Audacity 1.3 (Currently in version 1.3.13)
Note: Download the 1.3 version! Not the 1.2 version!
Part B
The second application you need is a video converter. It’s called VirtualDub
and the program is very easy to use and is shared for free - You’ll find it here.
Step 2
Part A
When you have downloaded the Audacity
EXE file, simply double click on the file and
install the application by following the
instructions on your screen.
When the application is installed, open the program by double clicking on the
Audacity icon. You’ll want to close the welcome window which pops up when
you have started the program for the first time.
Now you want to go to “File > Open” and open the movie file you are having
problems with. We are going to work with a regular .avi (xvid/divx format)
movie file. If you want to open other types of formats, see our FAQ for more
information. Depending on how fast computer you have and the length of the
movie it’s going to take a moment to open the file.
Note: If you are getting an error while trying to open your movie file in
Audacity you will need to install this add-on (FFmpeg for Audacity). This will
add support for several movie audio files. See our FAQ for more information.
Part B
Now let’s begin! First off you need to do is select the complete track, do so by
clicking “Edit > Select > All”.
Then select “Effect > GVerb...” and a window will pop-up with a few settings.
In the screenshot above you’ll notice the settings we use. We’re going to add
a slight audio effect to manipulate the original source audio, it is what makes
the movie play back perfectly on your Playstation 3 or standalone Blu-Ray
player.
The settings are as follows:
Roomsize: 1, Reverb time: 3.0601, Damping: 0.018, Input bandwith: 0.511,
Dry signal level: 0.0, Early reflection: 0, Tail level: -42,91. When you are done,
click “OK”.
For BluRay Rips use: Roomsize: 1, Reverb time: 2.0601, Damping: 0.018,
Input bandwith: 0.511, Dry signal level: 0.0, Early reflection: 0, Tail level: -30,91.
Tested on 30 Minutes or Less 2011
Not sure about DVDRip Settings yet
Note: You are welcome to try and adjust the level to suit your needs, the
settings above are made to be universal and will work on all movies.
Depending on your movie source, you will get a slight reverb effect on the
audio. This will hardly be noticable on retail movies, but if your movie source
has audio which was recorded with a microphone and already has echo -
Lessen the reverb time and tail level!
When you are done it’s time to save the audio file. Choose “File > Export...”.
Make sure you save it as an “MP3 files” similar to the screenshot above.
Note: Dending on your computer set-up you might need to install
something called an MP3 codec (titled “LAME”). The application will promt
you for a DLL file, if it’s missing. Simply download it here, install and go into
Audacity and save your audio file again.
Step 3
Now we’re going to add our new audio back onto the movie! We’ll use the
application Virtualdub, an excellent piece of software. Download it here.
Step A
Install the software by extracting the ZIP file. Inside
you’ll find a file called VirtualDub.exe. Once it’s
started, select “File > Open...” and choose the
original video file you had problems with.
Note: If your movie file can’t be imported to
VirtulDub, use AviDemux instead. Read more in our FAQ section.
Step B
Go into “Audio > Audio from other file...” and
choose the audio file we saved in Audacity. You’ll
be asked to choose “Bit rate”, but leave it on
default which is “Autodetect”.
Before saving the new movie with our new audio, we’re going to make sure of
two things - Click on “Audio” and make sure that “Direct stream copy” is
selected, similar to the screenshot above.
Next, make sure that under “Video” the “Direct stream copy” also is selected.
Now it’s time to save your movie.
Choose “File > Save as AVI” and save your file.
And !re we go! You are all done!
For Playstation 3 users we highly recommend using the PS3 Media server.
For Blu Ray users we recommend burning your movie file onto a CD-R or
DVD-R.
While it might have taken a while, next time you’ll have all the applications
installed and it’s going to be smooth to simply open the movie in Audacity,
then open the movie and audio file in Virtualdub and save.
Problems? Questions? View the FAQ section below.
Still can’t find an answer? Don’t hesitate to contact our e-mail support!
Don’t forget to include the movie title you are having problems with.
FAQ
I get an error while opening the movie file using Audacity.
Install this add-on (FFmpeg for Audacity), it will add support for the most
common movie and audio formats.
The audio sounds distorted and/or too loud.
The gVerb effect layers a slight volume increase, if it’s too loud - When you
are done adding gVerb. Select the audio and click on “Effect > Normalize” in
Audacity. Leave the settings at default and click on “Ok”. If it’s too loud and
still makes distortions, use the “Effect > Amplify” and select “Amplification
(dB): -5”.
I can’t open my video file in Virtualdub
Use AviDemux instead, you can download it here. Use Audio -> Main Track...
to replace or add audio track to the video file. AviDemux supports most video
formats like DVD, VOB, AVI, DivX, XviD, WMV, MPG, MP4, AVI, MOV, MKV,
DV, FLV.
I still can’t open h264 MP4 and MKV files
You can open h264 MP4 and MKV files directly in VirtualDub 1.8
Download this package: http://www.virtualdub.org/beta/
DShowInputDriver-0.5.zip Place it in the plugins32 folder under VirtualDubs
program directory.
The audio has an echo effect
This is because of gVerb, since it adds a slight reverb effect. You can try and
lower the settings, especially if you have a movie which already has low
audio quality
