Project Description
TRILOGY is a multidisciplinary basic research project that was designed to address three specific subject areas: optical networks, audiovisual P2P services, and sensor networks. These three areas were to be studied in a complementary fashion from the physical layers to future or new-generation Internet service layers. Seven research groups from three different universities collaborated on the TRILOGY project:
  • Optical Communications Group (GCO) of the UPC
  • Optical Networks Group of BAMPLA (GXO - BAMPLA)
  • Network Technologies and Strategies Group (NeTS) of the UPF
  • Audiovisual and Multimedia Technologies Group (TAM) of the URL
  • The Computing Laboratory of the Barcelona School of Informatics (LCFIB) and the Laboratory of Information Modelling and Analysis (LIAM) research group
  • BAMPLA Media Group (MEDIAENTEL – BAMPLA) of the UPC
  • Wireless Networking Group (XSF) of the UPC
Benefits for the Client
CoolRuc Platform that facilitates research and integration of new modules to improve live streaming systems. Specifically:
  • Lower broadcast cost for a channel: anyone can broadcast a channel
  • Scalability: the system is self-scaling and self-organising; data availability increases with the number of users
  • Bandwidth requirements: the upload bandwidth of the nodes is shared
  • Adaptation of quality: the video encoding module enables video quality to be adapted to the resources of the device
The intention of the TRILOGY research project was to open new research lines that would enable the transformation of live streaming systems into more standard, efficient systems with more features and to prepare them for 3D systems and HD transmission in line with cutting-edge audiovisual research.
