TV & Media: the IP imperative | WhitePaper & Infographic by Ericsson Time to Play

The impact of the internet on our daily lives is the biggest technological innovation of the last decade. It has re-shaped our planet, our lives and global industries – including TV and Media. Recent years have seen global broadband IP capacity enable the explosion in video- enabled connected devices. The IP era of TV is enabling richer and broader TV experiences that is transforming consumer behavior and enabling new industry players. 
The path to 2020 and beyond is clear – the need for more speed, more capacity and more immediacy will re-define delivery networks, spectrum allocation and business models. 
Consumers will embrace the experience of discovery, recommendation and consumption that only IP can provide across all their devices. The IP Imperative Game Changer highlights just how critical IP networks will become to the entire media value chain, but especially in the delivery and consumption of TV content by 2020.


Diving into ultra-low latency for live streaming using MPEG-DASH – GPAC Licensing

Low latency with HTTP-streaming (segment-based) technologies is a challenge. In particular MPEG-DASH is gaining adoption among international industry consortiums such as DVB with DVB DASH or ETSI with HbbTV 2.0 (not published yet), with a growing focus on live use-cases. For such applications, latency is a concern.

In this article, we will show you how the GPAC team studied the impact on the overhead of HD streaming with very low latency using MPEG-DASH and demonstrated that overhead on the transport side is negligible, in the order of 1%. At 1% overhead, we could demonstrate a 240ms latency. With such a low latency, interactive or bidirectional applications such as video conferencing or live streaming with voting become possible.

Of course such low latency can only be safely reproduced in local network conditions. Yet it shows that the latency is not due to the MPEG-DASH technology but rather to the network conditions. It also shows that a few technical choices can dramatically reduce the latency.
