We are happy to announce that our colleagues Christian Herglotz, Matthias Kränzler, Robert Schober and André Kaup published an article in the  Magazine of the IEEE Circuits and Systems Society. The paper is entitled “Sweet Streams are Made of This: The System Engineer’s View on Energy Efficiency in Video Communications” and deals with the holistic energy consumption of online video systems.

The paper shows how much energy is consumed on each part in each part of the pipeline, namely the provider-side server famrs, transmission, and end-user devices. Furthermore, recommendations are derived on how to configure an online video service such that the overall energy consumption of the system is minimized.
