Reduced energy consumption for the same video quality thanks to Nested

Reduced energy consumption for the same video quality thanks to Nested

With the exponential growth of streaming, an innovation like Nested allows you to significantly reduce its ecological footprint.

According to one study at the University of Zurichwith 4.6 billion broadcastsbroadcasts streaming worldwide at the time of the study (8 billion today), the song Despacito, by Luis Fonsi, consumed as much electricity in less than a year as Chad, Guinea-Bissau, Somalia, Sierra Leone and the Central African Republic combined “. In question the video streaming transmission, which” uses 80% of bandwidth globally “. As a result, a lot of innovations emergingemerging to reduce the impact of streaming, both at the data hosting level in databaseuser consumption and transmission asecosystemecosystem video streaming optimized for 5G5G from nested.

Low power consumption for the same video quality

nested (New video standards for advanced delivery) was developed by Ateme, in collaboration with Orange and its subsidiary Viaccess-Orca. The idea is to provide a energy consumptionenergy consumption reduction of terminals and network devices with the same video quality, optimized for 5G. If the solution is available now, after two years of development, on current equipment after a simple upgrade SoftwareSoftwarewill give its full power with the advent of 5G SA technology in the next three to five years.

Optimization of resolution and transmission format

The first innovation concerns the implementation of a new codec, VVC/H.266, which allows you to halve debtdebt video, and therefore its impact on carbon. The solution is also capable of automatically changing the format of the video stream, unicast where each stream is transmitted individually, or multicastwhere the same feed will be sent to multiple users, with none impactimpact visual for the user. It also allows you to optimize the resolution taking into account the screen used and offers a mode ecological which gives the user the possibility to get involved in the process by choosing the most suitable resolution for his equipment.

5G is expected to be 10 times more energy efficient

Even if most of your fingerprint is from constructionconstruction devices and not their use, as specified Ademe, a lot of decisive progress has been made in terms of mobile network power. Networks 4G4G they are about five times more efficient than networks 3G3G and 50 times more than 2G networks! And 5G technology is expected to be 10 to 20 times more energy efficient. powerpower compared to 4G by 2030. A significant contribution, considering that 4G and 5G networks together are expected to carry around 83% of mobile traffic in 2023.
