Digital Rights And Digital Television

Purposes of DRM Curb misuse of content Enable new content business models Track content usage Lock consumers into technology platforms or content formats © 2007 GiantSteps 2 Media Technology Strategies

Perspectives on DRM “DRM technologies … keep honest people honest” -- Fritz Attaway, MPAA “Trying to make digital files uncopyable is like trying to make water not wet” -- Bruce Schneier, BT Counterpane (noted cryptography expert) © 2007 GiantSteps 3 Media Technology Strategies

The DRM Conundrum  Content owners – …require technical protection as condition of licensing – …try to fight the piracy battle on all fronts (law, technology, education) – …will not subsidize DRM  Technology vendors – …want to sell new technologies that implement new content models – …see the Digital Home as the next huge opportunity – …see DRM as a necessary evil to get content licenses  Consumers – …want to consume content in convenient ways – …may enjoy new business models (e.g. subscription services) – …generally dislike DRM © 2007 GiantSteps 4 Media Technology Strategies

Head End to Gateway Device Successor technology to Conditional Access Encrypt the link – Cable, satellite, IPTV Pass along rights information – From offers in subscriber management system – To gateway device, e.g. STB Minimize cost of incremental hardware in gateway device – Encourage adoption by gateway device makers © 2007 GiantSteps 7 Media Technology Strategies

Gateway Device to Personal Network Allow reasonable use throughout personal networks – Play on any monitor – Store for playback later – Transfer to portable device Content owners becoming comfortable with this Consumer electronics makers see next big market Consumers generally scratching their heads (so far) © 2007 GiantSteps 8 Media Technology Strategies

DRM Schemes for Personal Networks: The Axes of Power  Goal: become the control center & gatekeeper  Set-top box axis: NDS, Thomson, Humax, Pace Micro,… – Secure Video Processor (SVP) Alliance  Media player axis: Sony, Philips, Samsung, Matsushita – Marlin  Mobile handset axis: Nokia, Motorola, Sony Ericsson,… – Open Mobile Alliance DRM 2.0  Microsoft (axis unto itself): – Windows Media DRM, Microsoft Media Transfer Protocol  Apple – Maybe, someday… © 2007 GiantSteps 9 Media Technology Strategies

Interoperability Among existing DRMs – Coral Consortium (standards group): everybody but service providers De facto standards – See “axes” Escape to analog – Domain of copyright law and Fair Use Hack – Anticircumvention law © 2007 GiantSteps 10 Media Technology Strategies

Video Fingerprinting  Examining content in order to identify it – “Take its fingerprint” – Filter: block identified content from upload – Or do something else – serve a related ad, charge a fee, etc.  Reasonably proven technology for music – Less proven for video  Bone of contention in Viacom v. Google litigation – Attempt to extend Grokster and secondary liability law to include a duty to filter  Focus of “UCG Principles” document – CBS, DailyMotion, Disney, News Corp, NBCU, Veoh, Viacom, Microsoft – Encompasses fingerprinting or watermarking © 2007 GiantSteps 12 Media Technology Strategies
