Peer-to-Peer Live Streaming: Innovations and Legal Implications from StreamTorrent

In a meeting held on September 20, 2006, at the University of St. Gallen, members of ETH Zurich’s Distributed Computing Group presented StreamTorrent, a peer-to-peer live streaming infrastructure. This innovative platform allows users to publish their own streams—ranging from sports events to TV shows—making them searchable and downloadable by others. The system is designed to be scalable and resilient without the need for dedicated servers. Key discussions included technical solutions and vital legal considerations regarding content responsibility and potential collaborations with TV stations.

  1. Peer-to-Peer Live Streaming Philip Frey Thomas Locher Remo Meier Stefan Schmid Prof. Dr. Roger Wattenhofer Distributed Computing Group, ETH Zurich Meeting with University of St. Gallen, FIR-HSG September 20, 2006

  2. Goals of StreamTorrent • Users can publish own streams over our infrastructure • Sport events, DJs, VJs, etc. • Can be searched and downloaded by other users. • Offering own streams? TV-shows? Movies? • Collaboration possible? • Similar to Zattoo? • Features: • Scalable to thousands of users. • Resilient against malicious users, churn, ... • Peer-to-peer, no dedicated servers needed. • Streams available everywhere in the world (behind firewalls, NATs, etc.). • “Pause Button”, (Programmable) Recording (like VCR!), … Remo Meier and Stefan Schmid @ HSG Meeting, 2006

  3. Demo Remo Meier and Stefan Schmid @ HSG Meeting, 2006

  4. From Computer Science to Law… • Having solved the technical problems, we have to learn about the law! • Sample Questions: • Are we responsible for contents streamed on our StreamTorrent infrastructure / with our software? • Are uploading peers responsible for the contents? • What contracts are possible with TV stations? E.g., streaming SF2 to the U.S.? (License?) • Separating protocol, player, and web sites? • Switzerland vs. Europe vs. World? • Other legal threats? Is it realistic at all? Tendency in future? => Cooperation with HSG, e.g., a master thesis? Remo Meier and Stefan Schmid @ HSG Meeting, 2006

  5. Thank you. Thank you for your attention! Remo Meier and Stefan Schmid @ HSG Meeting, 2006
