Sustainable OTT Video Distribution Powered by 5G Multicast/Unicast Delivery and Versatile Video Coding

Video services traffic over the internet has drastically grown these past years, currently representing more than 80% of the internet bandwidth [1]. The massive usage of unicast delivery leads to network congestion that can result in poor quality of experience for the viewer, high delivery cost for operators and increased energy consumption. In addition, the current methods for adaptive video streaming rely more on maximizing the video quality for a given bandwidth rather than minimizing the end to end (from video server to end user display) energy consumption for a given level of quality. This paper aims at leveraging recently standardized delivery technologies and video coding technologies to maintain the video quality while monitoring and possibly reducing video energy footprint and delivery costs.
