GMSys 2023: First International ACM Green Multimedia Systems Workshop, 7 – 10 June 2023, Vancouver, Canada

The threat of climate change requires a drastic reduction of global greenhouse gas (GHG) emissions in several societal spheres. Thus, this also applies to reducing and rethinking the energy consumption of digital technologies. Video streaming technology is responsible for more than half of digital technology’s global impact [ref]. There is rapid growth, also now with […]
