The development of the use of OTT (over-the-top) video services is illustrated by the exploitation of an impressive figure of 70% of the internet backbone bandwidth. Although there is room for eco-friendly improvement, as often users are provided with a unicast mode, a challenge remains on how to avoid congestion on distribution networks, thus requiring anticipating new investments and potentially new solutions.

Along with the rapid growth of OTT, the environmental impacts of digital services, and by extension video services, have become a major concern in our society. Searching for new ideas for more sustainable video distribution solutions is necessary to best accommodate the needs for more services taking the environmental impact into considerations.

Deloitte, with the supervision of Thales Alenia Space (TAS), worked on a dedicated study with the support of the National Centre for Space Studies (CNES) under the Telecom phase A program to identify the benefits of a terrestrial/satellite (geostationary) convergence on these use cases.

The objective of the study is to assess the environmental impacts of 100% terrestrial, 100% satellite then an eco-friendly hybrid (combined terrestrial and satellite) video distribution solution, in a given European and African area by 2030. The study uses LCA as a methodology and assesses the environmental impacts focusing on content distribution, where the main complexity regarding the management of different types of networks (terrestrial and satellite, Backbone Transport and Access networks) and functionalities (broadcast, multicast, unicast) are located, and where many different actors may interact in cooperation and/or in competition. At the end, the environmental benefits of optimising video distribution in a hybrid terrestrial and satellite configuration are presented.

As an opening conclusion, the future challenges in integrating upcoming societal trends, need for sobriety, rebound effects and regulations will also be addressed.
