Low-delay streaming and rapid channel switching capabilities are key drivers for media consumers to spend time on a video platform. However, reliable, high-quality video streaming for live events still poses significant technical challenges, and long delays are still common. LIVE-G will overcome these challenges by designing and building an end-to-end pipeline, including video coding, transport and delivery, that can be used for optimal video contribution and distribution over 5G networks.
Video media consumers value low-delay streaming of live events such as sports matches and concerts, as well as the ability to switch between channels at the click of a button. But broadcasters are technologically hindered in meeting these demands, and it is expensive to acquire the live streams and deliver them to broadcasters’ control rooms. As a result, delays that are seconds – and even tens of seconds – long are common.
5G mobile connectivity technology offers important improvements over 3G and 4G, including higher reliability and data throughput as well as much lower latency. As a result, it is a strong enabler of high data rate and mission critical applications in IoT, AR and VR and enhanced mobile broadband – including low-latency, end-to-end contribution and distribution for live event broadcasting.
In creating an end-to-end, 5G-based pipeline for live-streamed video contribution and distribution, the LIVE-G consortium will tackle five innovation goals:
In the course of the project, the LIVE-G consortium will contribute to domain know-how by creating patents, reports, papers, new technologies, algorithms and software modules. Even more, the project will produce a demonstrator to illustrate how far delays in live video streaming can be reduced using 5G for contribution and distribution in both lab and real-life environments.
