    Copy Protection Technical Working GroupNext Meeting - SEPTEMBER 11, 2002

  2. The "broadcast flag" by Anonymous Coward · · Score: 0 · on More on the Effect of Digital TV
    The "broadcast flag" is just a packet in the MPEG stream saying "by the way, don't let anyone make a digital recording of this". The various laws being considered now are to outlaw any device that ignores this flag or can be hacked to ignore the flag. Obviously, without such a law, it would be easy to buy a receiver that ignores the flag. The flag's technical name is the "ATSC Redistribution Control" descriptor.

    See, for example, this draft (PDF), and this report (MSWord doc).

    Technical information is available from the ATSC website. The RC descriptor is in document A/65A, Amendment 3.

  3. Who they? by Observer · · Score: 1 · on MPAA to Senate: Plug the Analog Hole!

    Looking at the PDF presented to the Senate Judiciary commitee, I noticed that this "Copy Protection Technical Working Group" is represented on the first page as including representatives of consumer groups, but on page 7 these aren't mentioned. The CPTWG site itself isn't exactly overwhelmingly informative about its membership, either.

  4. Re:Hardware Geeks by gnuradio · · Score: 1 · on GNU Radio

    The content folks at the MPAA Copy Protection Technology Working Group are already sweating. I spoke to them in February about free software, software defined radio, GNU Radio and our ATSC receiver project. The audience was about 1/2 techical and 1/2 lawyers. The lawyerly side from the content producers are the folks bringing you the Hollings bill.

    Some of the technical folks from consumer electronics companies were sure that what we are doing was impossible, and even if we could do it, no self respecting engineer would *gasp* give the source away. A few of them were more sanguine and understood fully the implications of what we're building.

  5. Dig TV = "Digital Rights Management", EFF Alert by Seth+Finkelstein · · Score: 4, Informative · on FCC Pushes Digital TV and Digital Restrictions
    It's explained very well in this EFF alert
    After 2006, the FCC will require all over-the-air broadcasts to be digitally encoded. Under the pretext of preventing the "Napsterization" of their video signals, the MPAA has convened the Broadcast Protection Discussion Group (BPDG) of the Copy-Protection Technical Working Group (CPTWG). The BPDG's "standards," developed in concert with a group of arm-twisted representatives from major technology vendors, will specify flags controlling the public's ability to store, copy, and share digital TV signals.

  6. Same guys that brough you CSS... by hughk · · Score: 2 · on Anti-Copying TV Technology Creeps Forward
    Don't worry. This will be from the same guys that brought you the Content Scrambling System (CSS) for DVDs and we know how serious that was.

    Still that was serious enough for the developer to be persued through his home country's courts.

    Timeshifting is now a part of everyday life. Slowly, it is no longer an elite group that can set the timer on a vcr (devices like TiVo, help a lot) and a lot of people time-shift.

    It doesn't matter wherether it is a broadcast premiere of a movie or a sports event, both may be time-shifted, and quite legally too! This is going to upset a lot more people than the CSS business and will not do anything for industry credibility or compliance.

  7. Re:Still don't understand by ewhac · · Score: 2 · on SDMI Cracked Too Soon

    Am I missing something?

    Possibly. The latest version of WinAmp has copy protection (misleadingly referred to as "digital rights management") designed by InterTrust Technologies.

    It's quite possible your shiny new version of WinAmp will refuse to play your ripped MP3.

    More broadly, the RIAA and MPAA's strategy is to collude with electronics and software vendors such that copy protection-free systems never reach consumers. A quick look at the roster of attendees of the Copy Protection Technical Working Group should illustrate this.
