Watermarks can survive multiple re-encodings and could be applied at the source 
without anyone further down the chain being aware of them.

  Richard;

  In general, this is "possible."  However, the information you provided was 
either prospective, or relating to the IPTV market.  This was, simply, a 
broadcast situation.  NBC's content is encoded from 45 mb feeds at broadcast 
stations, and this is not a feature of broadcast encoders.  Yet.

    Video programs are being "watermarked" at several steps in the
    distribution chain so that when a video shows up as an
    unauthorized BitTorrent release, the owner of the cable box can
    be traced....also if it's an inside job at headend.  For example:

      Gefen does offer a box that converts to SDI with the HDCP turned off.  
However, you have to sign a release that says all the content you intend to run 
through the box you OWN yourself.  Not sure how they would police that!!!
