According to one study at the University of Zurich, « with 4.6 billion streaming broadcasts in the world at the time of the study (8 billion today), the song Despacito, by Luis Fonsi, consumed in less than a year as much electricity as Chad, Guinea-Bissau, Somalia, Sierra Leone and the Central African Republic combined “. In question the broadcasting in video stream, which ” uses 80% of the bandwidthbandwidth globally “. As a result, many innovations are emerging to reduce the impact of streaming, whether at the level of data hosting in data centersuser consumption and transmission like Nested’s 5G5G optimized video delivery ecosystem.
Reduced power consumption for equal video quality
Nested (New vidEo STandards for Enhanced Delivery) was developed by Ateme, in partnership with Orange and its subsidiary Viaccess-Orca. The idea is to provide a energy consumptionreduced energy consumption of terminals and network equipment for equal video quality, optimized for 5G. If the solution is now available, following two years of development, on current equipment following a simple software update, it will give all its power with the advent of 5G SA technology within three to five years.
Optimization of resolution and broadcast format
The first innovation concerns the implementation of a new codeccodec, VVC/H.266, which makes it possible to halve the bitrate of the video, and therefore its carbon impact. The solution is also able to automatically change video streaming format, unicast where each stream is transmitted individually, or multicast, where the same stream will be sent to multiple users without any visual impact for the user. It also makes it possible to optimize the resolution taking into account the screen used and offers a mode eco-friendly which gives the user the opportunity to get involved in the process by choosing a resolution best suited to his equipment.
5G should be 10 times more energy efficient
Even though the majority of your digital footprint comes from constructionconstruction of the devices and not of their use, as specified Ademe, many decisive advances have been made in terms of mobile network energy. 4G4G networks are regarding five times more efficient than 3G networks and 50 times more efficient than 2G networks! And 5G technology should be 10 to 20 times more energy efficient than 4G by 2030. A significant contribution, when we know that 4G and 5G networks should together carry around 83% of mobile traffic in 2023.
