Audio watermarking to HD-DVDs

3 November 2005 1:35 by Jari Ketola | 70 comments

Audio watermarking to HD-DVDs A new technology for watermarking movies has been unveiled at a conference held by the DVD Forum in Paris. The new technology relies on unnoticeable watermarks on the audio track instead of more commonplace image based watermarks. Future movies will include the watermarking on the audio track, and HD-DVD players will look for these marks on discs played on the device.

The watermarking works by encoding a digital signal to the audio track by varying its waveform. Even though unnoticeable to the human ear, the player can easily Decode the signal and detect if the copy has been made in a movie theatre.

Similar watermarking will be implemented on consumer discs as well. When such a watermark is detected, the player will check if the disc played is genuine or not, and if it's not, the player will shut itself down.

In order for the player to determine the copy illegal the watermark signal must be present for an extended period of time. That should prevent the "false positives" that could be caused by, for example, taking a home video in an environment with a watermarked movie playing in the background.

Electronic Frontier Foundation's intellectual property attorney Fred von Lohmann is somewhat concerned about implementing a new watermarking technology. "For any watermarking scheme to be effective, technology companies have to be forced to re-engineer playback devices to detect the watermarks," von Lohmann told New Scientist. "The risk is that Hollywood starts dictating the redesign of existing DVD drives, CD drives, hard drives, and personal computers, all to buttress the watermark."

Watermarking can be very effective indeed in preventing pirated copies from being viewed on next generation players. With HDCP being mandatory on all "HD Ready" devices, the entertainment industry is pretty much making sure that no HD player with the watermark check bypassed will be able to enter the market.

    You will require a NEW DVD player (settop and/or PC) to use the new formats. At that time, as part of the licensing the manufactures will be compelled to follow certain standards just as they are required to do so now. This goes equally for hardware and software players as if they do not comply they will not be issued an encryption key (any search on css/de-css can give a 'simple' explanation of how the devices work and could be applied to future devices) enabling them to decrypt the info on the disc thereby allowing it to be played. No subversion of MB's will be required (though that would sure make the industry happy and is certainly where they eventually would like to end up!)

    Some very interesting posts have been made today. I learned a great deal. Thanks to all of you.
    I did want to make one last comment. Do you remember what
    happened to Circuit City and the hollywood legal firm that
    invested millions in the DivX dvd scheme. We were going to pony up th the bar and pay $4.50 for a DVD that we could
    watch for 24 to 48 hours and then it would sign off unless
    we used our telephone line to pay for re-activation.
    We were also going to have to buy a special DVD player.
    WELL IT WENT BELLYUP IN NO TIME. CIRCUIT CITY STOCK TO A BIG HIT ON THE MARKET, AND I LAUGHED MY BUT OFF.

    OK Back to th e watermarking thing: Wouldn't it be smarter of them to try and get all recorders to shutdown when they hear the watermark? I mean-doesn't it seem like when you move the movie from the recorder to the computer, that people will unlock whatever algorithms or whatever that the players use to recognize the watermark-and remove the watermark from the file? This doesnt seem like it'd be too hard. Putting it into the camcorder would, on the other hand, almost surely require a hardware fix. Just my two cents.

    good thinking persbian, make it harder for the people that film the movies instead of punishing everyone that buys dvd's, it makes alot more sence to do it your way.

    for those of you asking about whythe announcment combines movie THEFT via taping a new release from a theater screen, with consumer hd-dvd disks, I strongly suggest you consider this is not just about technology propaganda and p.r move.

    once again the entertainment industry is combining in the public mind outright theft with consuemer rights.

    this technology is interesting technically, but we get these same announcments every few months -- the message is alwasy the same, thieves and people seekign options for the films they actually pay for are the same.

    in two to three years when hd films on hd tv become widely avaialbe to the pubic, I am going to want to do what I have done with my audio and my normal density dvds -- put them on hd for ease of use/avaialblity. I have audio players that don't use physical media, and my video player in my car is a an xbox where I keep 40 films which I alternate.

    my beahvior, despite paying for the IP, is in argument of the RIAA and the mpaa, the same as a guy who films a theatrical relases and sells it. they intend to use the same technology against me -- and irony on top if irony, force me to pay the premium on the hardward i will have to buy with their protection mechanism as well!

    VIVA LA REVOLUCION!!!! I will gladly, happily (spelling?) and graciously invest money wether it be $1 or $1000, into developmental and successful programs that will rip these protection shananigans to shreds, or blow new A holes in their protection programs. I believe when you pay for a product you have the right to do whatever the hell pleases you to do with that product.You paid for that piece of the pie, you should be able to eat it how you see fit!! VIVA LA REVOLUCION!!!!

    A reminder

    AnyDVD tackles Sony DRM Rootkit Virus!
    If AnyDVD is installed and active on your PC, the new so-called "Sony DRM Rootkit Virus" has no access to your system and the affected audio CD appears unprotected regardless! Another good reason to get AnyDVD!

    Now we have to hope the government of Antigua is responsilble enough not to be bought by Hollywood.

    Anyone taking bets on whether or not there are new homes and children's college tuition in the works for the members of this government?

    HDTV2DVD build 0.4 has been released - back up that HD-TV content!
    Posted by Jan Willem on 04 November 2005 - 19:39 - Source: HDTV2DVD

    The creators of SVCD2VCD have released a new version of HDTV2DVD. This is a new freeware tool to simply convert your HDTV material to DVD. HDTV captures are MPEG-2 Transport Streams at either 1280 x 720p or 1920 x 1080i resolution yet DVD is typically MPEG-2 Program Streams at 720 x 480 (for NTSC). This means that to play HD material on a "normal" DVD player you have to convert the source. This is what HDTV2DVD does in an user friendly way.

    By loading up your HDTV file (.ts or .tp), start the processing and HDTV2DVD will produce a VIDEO_TS DVD folder which you can burn.

    Build 0.4 - 03 11 2005

    * Improved aspect ratio logic: now supports 4:3 as well as 16:9 source material.
    * Added clearer progress bar.

    Build 0.3 - 27 09 2005

    * Added high bitrate matrices to improve encoding quality

    Build 0.2 - 23 09 2005

    * Initial public release

    More information and a download link can be found here. Of course both our Video Edit Software and Satellite, HD-TV, Blu-ray and HD-DVD Forum are the right places to discuss this software.

    I found this article on PCWORLD.COM http://www.pcworld.com/news/article/0,aid,122928,pg,3,00.asp

    Apparently they want to offer what's called 'managed copy' or the fair backing up of copies of DVDs

    Sounds too good to be true.

    just like the 45 and 33 music records was replaced by the casset,the casset replaced by the cd,the vhs replaced by th dvd and so on,no doubt the standard dvd will eventually be replaced by the blue-ray and hd-dvd.it will probably take some years before they stop making the standard dvd primarily because there are so many standaed dvd players out there that the movie industry realize there is still a lot of money to be made if they continue to produce the standard dvd for some years to come after the start of marketing blue-ray and hd-dvd.if you notice the dvd has replaced the vhs for some years now but they comtinue to produce vhs movies.the bottom line is that there is a lot of vhs and dvd players out there and money to be made so don`t look for any drastic change as far as dvd and vhs in the near future.look at it this way,how many of us will be willing to shell out between 500 and 1000 dollars for a rlue-ray hd-dvd player,this is an estimate of what they will cost and it could be higher.

    Very interesting discussion. So will regular DVDs be replaced by HDDVD or BlueRay. I'm not an expert, but my opinion is probably not for a long time.

    1. DVD is now the defacto standard for Home Video Viewing other than off the air or Sat TV.
    2. If you don't have a DVD Player (shame on you), you still have a VHS unit. (my mom and dad). And you probably don't care.
    3. So when the biggies release Blue Ray and HDDVD and the general consumer market finds out that, "wait, you mean I can't play the new discs in my Standard DVD player which I just got?" Both Blue Ray and HDDVD will suffer. Just like SACD and DVD-A have.

    People are satisified with their DVD playback quality, remember, most of the people in the world who own a TV and DVD, think that DVDs are the greatest thing since sliced bread. And when you tell them that DVDs are being phased out,,,,well,

    I just don't think standard DVD Video will go a way in the near or for that matter forseable future.
