Hadopi
DRM regulator in France➢ ARMT➢ Has no idea what they speak about
Different kind of saisines➢ Contentieux one specific DRM➢ Generic question about DRM law and application
French law➢ You can circumvent DRM, in order to achieve interoperability,
without limiting the authors rights
Hadopi Questions
Request of a generic Hadopi saisine :● What are the conditions to share the keys ?● What are the conditions that can be imposed on us by
copyright holders (HDCP) ?● Can we distribute :
– Source code of DRM library?
– Static build of DRM library in a player?
– Shared object of DRM library ?
– Keys ?
Hadopi Answer
● 17 months to get an answer– Legal 3 months
– Pressure with public question in Assemblée Nationale and press
– Vague meetings and repeated lies about delays
● The answers are :– For the keys, you should ask Sony, and create a contentieux
– Keys are not part of the source code
– …
– No answer on any of the important questions asked
● Back meetings with AACS-LA, Sony– Lies and document not shared
Codecs
Codecs– Heavily patented
● Including base math● Very expensive to licence● Numerous patents → Cartel of exchange
– Very aggressive● Dolby, DTS● MPEG-LA
– Not valid in France (EU)!
Dolby Lobby
● Used everywhere– Dolby Digital
● DVD, Blu-ray, TNT
– Dolby-E
● Dolby Digital (AC-3)
– DVB and ATSC spec– ETSI
– is MANDATED by the CSA
● Heavily Lobbied– E-AC3 in France, thanks to Canal+ (reduced fees from Dolby)
– All profesional products have Dolby-E
Dolby Scam
The Dolby Scam● One licence only
– IP : codec implementation, patents, certification, logo
● No way to license only the patents– 20 years !
– Refusal to share patents list
– No respect of DVB or ETSI obligations
● Use of DMCA and LCEN– Because IP !
● Everyone is scared– Except the CSA :)
