2004/09/14Wedelmusic 2004, Barcelona, 8 Some already Existing Technologies (2)  Matching and Data-mining usages profiling usages profiling “users who like this song also like these songs” “users who like this song also like these songs” user matching user matching  Less Restrictive DRM protected on the HiFi system protected on the HiFi system copying to potable device is allowed if the user signs the file copying to potable device is allowed if the user signs the file it prevents large scale copy law violation it prevents large scale copy law violation

2004/09/14Wedelmusic 2004, Barcelona, 9 The Sharing System  Protected P2P sharing network direct message, music and metadata transfer between two HiFi systems direct message, music and metadata transfer between two HiFi systems signed licenses prevent illegal sharing signed licenses prevent illegal sharing closed groups closed groups based upon JXTA 2 open source framework based upon JXTA 2 open source framework  Possible use-cases for sharing users rip CDs for the service users rip CDs for the service service provider has to reward the users for ripping and staying online service provider has to reward the users for ripping and staying online reward is the access to more content reward is the access to more content

2004/09/14Wedelmusic 2004, Barcelona, 12 Automatic Mode  Plays user’s favorite music automatically  HiFi system generates automatically content requests for the sharing system  Requests calculated from users profiles  User profile stores user’s feedbacks: pressing the seek button (dislike feedback) pressing the seek button (dislike feedback) not pressing the seek button (like feedback) not pressing the seek button (like feedback) time of feedback also stored in the profile time of feedback also stored in the profile user’s profile is shared for other HiFi systems user’s profile is shared for other HiFi systems  Requests paid with sharing credits

2004/09/14Wedelmusic 2004, Barcelona, 13 SemanticHiFi EU Project  Browsing, listing, interacting, performing and sharing on future HiFi systems  IRCAM (Paris) has the leadership  Fraunhofer provides the sharing technology  Data to be shared within the P2P system: performing data generated by authoring software performing data generated by authoring software indexing data (descriptions of data) indexing data (descriptions of data) music is not allowed to be shared music is not allowed to be shared

2004/09/14Wedelmusic 2004, Barcelona, 14 Future Work: Mobile  Mobile phone plays user’s favorite music  Mobile operator stream songs  Play lists calculated from users’ profiles local profile visible for other mobile phones local profile visible for other mobile phones  Bandwidth of a UMTS cell is limited: several users have to share the same stream several users have to share the same stream the seek button brings the user to a new stream the seek button brings the user to a new stream  With German research center for AI (DFKI)
