  1. Jürgen Nützel Matthias Kaufmann Sharing Systems for Future HiFi Systems Wedelmusic 2004 Barcelona, 13th – 14th September 2004 Jürgen Nützel, TU Ilmenau Matthias Kaufmann, Fraunhofer IDMT

  2. At a Glance ... • Music will be a Service Again • The System we Dream of • Some Existing Technologies • The Sharing System • Automatic Mode • Relations to SemanticHiFi EU Project • Future Work: Mobile • Virtual Goods Workshop 2005 Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 2

  3. Music will be Service Again • 125 years ago • Next 120 Years • Today Artists performed live music The artists provided a service for the audience The music industry produced recorded music. They sold it like physical good. Some sell music like a physical good. Some provide an online service. • What’s next? • What’s next? • What’s next? MP3 ? Internet Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 3

  4. The System we Dream Of PC-based HiFi system with Internet connection CD/DVD Speaker + camera Color Display Volume Combination of remote control and portable player with flash memory or hard disk. Communication with HiFi System via Bluetooth. Reprogrammable Radio Buttons UMTS Mobile Phone? Multifunctional, reprogrammable controls Browse Select Volume Modify Sound Headphones Reprogrammable Dials Microphone Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 4

  5. What are the Main Usage Scenarios? • CD/DVD mode • user plays (and rips) audio CD or DVD • browsing mode • browses through genres, artists and songs • community mode • chats with users who like the same music • portable mode • transfers music from HiFi system’s hard disc to portable device or mobile phone • automatic mode • plays user’s favorite music automatically Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 5

  6. Business Models • Subscription • buy the HiFi system and subscribe the service • 1 Euro for HiFi system and 20 Euros per month • 200 Euro for HiFi system and 5 Euro per month • 400 Euro for HiFi system and free service • similar to mobile business !! Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 6

  7. Some already Existing Technologies (1) • Browsing and Searching Functions • „Query by Humming“ • AudioID (Fingerprinting) Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 7

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

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

  10. Architecture JXTA Content/Profile Transfer HiFi system (peer) JXTA Rendezvous peer(s) (routing mechanisms, etc.) HiFi system (peer) JXTA Advertisements SOAP/XML SOAP XML IPR-Management Server Trust Center, CA Sharing Component User & Group Management White List Metadata User DB AudioID DB Cert. DB Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 10

  11. HiFi System HiFi system user Sharing credits User’s interactions and feedback Local Content Content manager User certificate and profile Sharing Component using JXTA Web Service interface to central servers Internet Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 11

  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) • not pressing the seek button (like feedback) • time of feedback also stored in the profile • user’s profile is shared for other HiFi systems • Requests paid with sharing credits Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 12

  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 • indexing data (descriptions of data) • music is not allowed to be shared Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 13

  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 • Bandwidth of a UMTS cell is limited: • several users have to share the same stream • the seek button brings the user to a new stream • With German research center for AI (DFKI) Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 14

  15. Announcement Call for Papers: VirtualGoods.TU-ILMENAU.de 3rd International Workshop with Tutorials June 2 - 4 2005 in Ilmenau, Germany Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 15

  16. Jürgen Nützel Matthias Kaufmann Thank you Wedelmusic 2004, Barcelona, Juergen.Nuetzel@tu-ilmenau.de 16
