GAIA

Intelligent Climate-Friendly Video Platform

GAIA (Greek goddess of Earth, mother of all life, personification of the Earth) is a project:

Project Description

A growing number of digital technologies require power to run. Video streaming technology is responsible for more than half of digital technology’s global impact. In this context there is rapid growth, also now with remote and digital work becoming more mainstream, in the amount of video data volume, processing of video content, and streaming which affects the rise of energy consumption and its associated global greenhouse gas (GHG) emissions.

The GAIA project researches and develops a climate-friendly adaptive video streaming platform that provides:

  • Complete energy awareness and accountability, including energy consumption and GHG emissions along the entire delivery chain, from content creation and server-side encoding to video transmission and client-side rendering;
  • Reduced energy consumption and GHG emissions through advanced analytics and optimizations on all phases of the video delivery chain.
