Part 1 of this series described how network-side QoE (Quality of Experience) measurement is fundamental to proactively assuring the quality of OTT services. At its core, the network-side can be an early warning system for QoS, which in turn correlates to actual QoE performance. This article considers the two types of network monitoring available to us, relative priorities for the points of measurement, and how the video platforms contributing to OTT services are evolving to support OTT quality at scale.
The features we love about OTT services – such as combined linear and on-demand content, multi-device viewing mobility, tailored viewing experiences, and in some cases better resolutions – are driving the general rapid uptake of OTT services.
A core promise of OTT is greater customer satisfaction through a more personalised viewing experience. Instead of linear channels with scheduled content that we may or may not be interested in, OTT enables us to combine tailored VOD and Live content into a single viewing window. This specific personalised viewing dynamic tunes the experience more precisely for a consumer which in turn increases commercial value for advertisers and OTT operators. We should expect a win-win-win for consumer, advertiser and content provider.
Telco fixed access networks are “the last mile” to homes and commercial buildings. They play a key role in the delivery of OTT Video, and are undergoing big changes to support its growth. Telco fixed access networks were originally built in the 19th century to deliver telegraph services, evolving during the 20th century into telephone services. Today they provide vital telecommunications services supporting all aspects of a nation’s life including government, business, education and entertainment. Companies in this sector include the likes of British Telecom, Telecom Italia and AT&T. Over the last 30 years, the voice-first PSTN network has evolved to support data services over broadband, and today telco’s are deploying new data-first access networks.
In this article, George Kroon, research broadcast engineer, takes a look at how Negative ARQ protocols similar to those used for internet streaming and contribution can be improved specifically for broadcast television.
OTT has dramatically expanded the range of delivery outlets for content and continues to do so. This has had a direct effect on content production, enabling almost any organization or person to create and distribute live content, which has increased the volume of content being created. Whether this content is for entertainment, news, education or communications, video is our preferred communication medium and people generally turn to this whenever possible.
Demand for bandwidth is growing at a remarkable rate. The demand is so high that Equinix’s Global Interconnection Index (GXI) Volume 4 forecasts a 45% CAGR specifically for interconnection bandwidth from 2019-2023. This will bring global interconnection bandwidth, used specifically by businesses that need to guarantee throughput capacity, from 5,000 Tbps in 2020 to 16,000 Tbps in 2023.
OTT offers an amazing promise – to significantly increase the return on advertising spend by targeting consumers more effectively.
