Call For Submissions

As last year, GMSys focuses on energy reduction in multimedia systems, with a specific emphasis on video streaming. Video streaming accounts for over half of the digital data traffic and plays a significant role in the global impact of digital technologies on climate change. The demand for video streaming continues to rise, driven by  advancements in camera and display technologies, enhanced Quality of Service (QoS) provided by service providers, and the emergence of deep machine learning techniques. Consequently, the urgency to address the environmental footprint of video streaming has become more pressing. Video streaming involves several stages, including content production, provisioning, delivery, and consumption. Within these stages, the primary challenge lies in finding ways to make video streaming more environmentally friendly without compromising quality. Factors such as resolution, bitrate, device type, and network speed all play a crucial role in determining the resources required for video streaming, ultimately influencing energy consumption and emissions.

The International Workshop on Green Multimedia Systems 2024 aims to bring together experts and researchers to present and discuss recent developments and tackle the challenges associated with energy reduction in multimedia systems. This workshop focuses on innovations, concepts, and energy-efficient solutions from video production to processing, delivery, and further consumption. Please see the Call for Paper.
