A large scale trial of Low Latency DASH media streaming to viewers in the UK

What is it about?

As many content providers look to reduce delays in live streaming, and with new technologies emerging such as Low Latency DASH (LL-DASH), Low Latency Low Delay (L3D) DASH and Low Latency HLS, we present the results of a large scale trial of LL-DASH streaming to viewers in the UK using a wide variety of TVs and streaming devices. We outline the simulations, development and deployment that enabled us to deliver content with end to end delays matching broadcast, and present an analysis of around 20,000 low latency sessions from about 5,000 different IP addresses, comparing their performance with that of conventional streaming. Using the comprehensive monitoring and metric reporting put in place for the trial, we present new insights into the real world performance of low latency streaming. We show that our low latency trial was able to achieve similar Quality of Experience (QoE) for low latency streaming as for conventional live streamed services.
