Report on GMSys 2023: First International ACM Green Multimedia Systems Workshop

The first International ACM Green Multimedia Systems Workshop, hosted and organized as part of the 14th ACM Multimedia Systems Conference, took place on Saturday, 10 June 2023 in the beautiful city of Vancouver, Canada. This workshop served as a crucial forum for researchers in multimedia systems to present and share their latest research findings, with a specific focus on energy consumption and greenhouse gas emissions in multimedia systems.

The workshop featured eight high-quality technical presentations, with an impressive acceptance rate of 66.7%. These presentations included both full papers and short papers, showcasing a diverse range of innovative approaches and solutions related to green video streaming. It was a significant opportunity for multimedia researchers to come together and delve into this timely and important topic.

The workshop was the participation of  experts and researchers in the field of green video streaming. Researchers from universities including Fraunhofer FOKUS, Friedrich-Alexander-Universität Erlangen-Nürnberg, and university of Klagenfurt presented their research papers, shared their valuable insights and research findings, further enriching the discussions. Researchers from leading companies such as Synamedia, Amazon, and Ateme also presented their research papers and  actively participated in the workshop.
