Energy Efficient Video Processing

With the proliferation of social media, the volume of videos uploaded and shared on the Web has been continuously growing – and along with it the amount of energy needed to process, store and distribute them globally. Video coding standards have offered significant improvements in video quality, or equivalently, big reduction in bitrates while maintaining the same visual quality. Traditionally, such improvements in video coding carried equally significant, and as of late even more disproportionate so, increases in compute/energy requirements to deliver these savings. We will look into the problem of energy efficient video processing holistically and propose a few ways to address the growing demand in video processing through system-level optimization and by elevating energy efficiency to become a first-class citizen in future video coding standards.
