Audio watermarks let the MPAA know where a recording was taken, but not by whom
We've heard of some crazy audio watermark plans in the past, designed to prevent people from making copies of Hollywood blockbusters, and despite the audio industry finally moving away from its protective restrictions, the film industry seems to just keep working on more. The latest, created by Professor Noboru Babaguchi and his colleagues at Osaka University in Japan, is a means to apply spread-spectrum audio waveforms to a film's multi-channel soundtrack, enabling pirate seekers to determine exactly (well, to within 44 centimeters) where the bootlegger was sitting when he or she committed his or her felonious deeds. Interesting, sure, but unless all theaters worldwide start assigning seats by name it's useless. Beyond that, there's nothing stopping an intrepid recorder from stashing a mic a few feet to the left or the right, thus implicating an idle popcorn-muncher. Will these flaws keep this technology from being implemented? Don't count on it.[Via Slashdot]
Verance rolls out audio watermarking for HD DVD / Blu-ray
It's been so long since we've heard anything serious about audio watermarking that we were beginning to worry, but for the hackers up for yet another challenge in the realm of high-definition film, your brief wait is (nearly) over. Verance Corporation has just announced the immediate availability of its audio watermark technology for licensing by manufacturers of Blu-ray and HD DVD players and components, which means that users will likely face another layer of content protection when trying to free their movies from the bondage of DRM. No word just yet on a timeframe in which this stuff will actually make its debut, but it is noted that the AACS is "is expected to release final license agreements requiring the inclusion of VCMS/AV detector technology in HD DVD and Blu-ray players in the coming months."
