ADIMUS – Adaptive Internet Multimedia Streaming

The ADIMUS project looks at streaming of multimedia on the Internet. We implement methods that adapt to service quality changes, in order to maximise the end-user's subjective experience. Adaptation mechanisms include QoS reservations, encoding schemes and parameters, and routing. The modeling of end-to-end service quality will be used in simulations and evaluations. Issues like inter-dependencies between media streams, special requirements for non-entertainment media streams (e.g., medical applications), and transmission technologies (e.g., wireless, peer-to-peer) will also be included in the research. The project involves four research institutions, NR, VTT, SICS, and Ifi/UiO. The project supports two PhD students, one located at NR and one located at VTT; expertise from researchers of NR, VTT, and SICS, and assistant professors at the Institute for Informatics at the University of Oslo.

NR’s contribution

ADIMUS is an academic research project with NR being the project coordinator. One of the PhD students is supervised at NR.

Benefit for customers

New knowledge about multimedia streaming in the future Internet using overlays and multi-access networks will have an impact on service providers in the Internet.

Benefit for society

Multimedia content can be accessed through multiple access networks, each of which is based on different technologies. The (mobile) user is connected to the network in an optimal manner with regard to financial cost and quality.

Project results

We developed an algorithm to allow the (mobile) user to switch between access networks in order to optimize the connection. The multimedia data are delivered over an overlay network, containing multiple senders and multiple recipients. The overlay network's nodes perform routing, transcoding, hand-over technologies, and other necessary operations, while the technology for low-level transmission may change from time to time. The final project report is available.
