Live streaming has become increasingly widespread. With the addition of 5G, this service can be dramatically improved at all levels, including image quality, download times, interruptions and lag. Faced with today’s generations’ enthusiasm for live feeds, researchers are now working to adapt live streaming TV so it can be done on the go. The Goal: Lag-Free Live Streams Getting closer to what’s happening live is one of the main challenges in the field of live streaming. Yet, streaming over the Internet using Wi-Fi or 4G still results in a lag of 30, 40 or even 50 seconds on tablets or smartphones. This lag will particularly hit home for any soccer fans who have ever heard their neighbor watching TV and cheering for a goal they haven’t seen yet. It also affects participants in time-limited interactive TV game shows and televised broadcasts by figures of authority in relation to announcements, alerts or disasters, for example. Ensuring service continuity, particularly when faced with high demand, is another challenge of live streaming. At Orange Innovation, researchers are therefore thinking about how they can make improvements in the field of TV streaming on the go, using a combination of 5G, video streaming technologies (multicast, low latency), network bandwidth allocation (network slicing) and edge computing. Their work has primarily focused on mutualizing streams; a key way of saving bandwidth. Dominique Thômé, Product Manager Innovation Data TV, explains that “Unlike unicast technology, which broadcasts streams as many times as there are simultaneous connections, multicast should allow a single stream to be broadcast to thousands of people connected to a large 5G zone. This mutualization prevents bandwidth loss and, consequently, service interruptions from network congestion. Another advantage, which is of great importance to Orange, is that it consumes less energy and therefore contributes to the transition to a low-carbon economy.” Recognizing the Know-How of Carriers Experiments carried out in the Orange laboratory have yielded interesting results. A real-time readjustment of video quality to prevent network saturation resulted in each customer being able to watch TV with only five seconds of lag, confirming the feasibility of 5G live streaming on the go. In fact, faced with ever-increasing volumes, some broadcasters are beginning to turn to carriers to broadcast their TV streams. They need players that are able to transmit this huge amount of data while ensuring optimal quality, in order to avoid any latency problems. Thibaut Mathieu, Director of Innovation for Interactive & Multiscreen Services at Orange says that “Our pioneering approach toward 5G live streaming highlights the valuable role that network carriers play, right at the heart of the system, compared to OTT players (“over the top,” such as the Tech Giants), both in terms of technology and business. We will be able to get involved in data transmission, with optimal mutualization technology that will save money and energy.” These technologies are consistent with Orange’s CSR commitment, both in terms of carbon footprint (lower energy consumption) and inclusion (broadcasting the right information at the right time). More than Just Entertainment The challenge goes far beyond the traditional TV broadcasting market itself. In the context of the health crisis, brands have been quick to understand the value of live streams to generate sales and are starting to venture into “Live Shopping.” Originating from China, this large-scale approach to teleshopping consists of an online event where presenters, influencers or personalities showcase products live to a digital audience who are able to order products or ask questions. Live Shopping is attracting more and more brands around the world. “With hundreds of thousands of people connected at the same time, its large scale will certainly create capacity issues” says Thômé. “This is another case where mutualization will ensure quality of service.” Networks and IT  /  Article

Semiconductors, a strategic issue for the economy and innovation

A semiconductor is a material whose electrical conductivity value falls between those of metals and those of insulators. Thanks to its properties and its natural abundance, silicon is the most used semiconductor material, but there are many others. Components based on semiconductors – in particular, the integrated circuit, which brings together several electronic functions within […]

The Growing Transmission Capacities of Multicore Fiber

With the explosion of digital traffic—driven by more people working remotely, increased use of e-commerce, photo and video sharing, streaming and so on—and the ever-increasing number of applications constantly consuming more bandwidth, optical transport networks are under intense pressure. This underlying trend, amplified by the pandemic, is forcing network carriers to explore new avenues to […]

Chatbots are redefining interactions between customers and advisors

Who hasn’t come across a “chatbot” when making with a complaint or help request? They have become an effective first port of call before an advisor intervenes. And companies have capitalized on this value. They are willing to invest generously in this conversational artificial intelligence (AI) to improve its performance. In doing so, customers get […]

LiDAR

LiDAR, which stands for “Light Detection and Ranging”, is a remote measurement technique that uses the light from a laser to determine the physical properties of an object. The vast majority of LiDAR sensor applications are for telemetry – distance measurement. To determine the distance of an object, the LiDAR sends a laser pulse to […]

Fibre-wireless performance

Introduction In 1889, Nikola Tesla created a high-frequency radio generator. A few years later, he tested the world’s first wireless communication. Then, in 1897, Guglielmo Marconi accomplished the first radio communication, using Morse code signals, over a distance of 14 km in Great Britain. This marked the beginning of the remarkable progression of radio communication through […]

Spintronics

Spintronics is an emerging discipline that harnesses a magnetic and quantum property of the electron called “spin”. As its name implies, “spin” describes the angular momentum of a particle, i.e. the vector quantity that describes the rotation state of a system. This is due to its rotation upon itself, in the same way as that […]
