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.

"5G new radio (NR) sidelink (SL) is envisioned as a key enabler of high speed, low latency applications like automated driving. To meet the high data rate requirements for such applications, SL support at mmWave and sub-THz frequencies with large bandwidths will be essential. Several enhancements and optimizations will be...

"The increased mobile connectivity, the range and number of services available in various computing environments in the network, demand mobile applications to be highly dynamic to be able to efficiently incorporate those services into applications, along with other local capabilities on mobile devices. However, the monolithic structure and mostly static...
