- Abstract
- Recent events, such as the 2018 FIFA World Cup, demonstrated that live over-the-top (OTT) experiences have some serious limitations, including low quality on TV sets and a delay of more than 30 sec compared with broadcast services. If the industry does not solve those problems, they could halt the development of live OTT offerings. This article analyzes the current challenges involved with delivering live OTT services and will describe solutions that are available today, such as content-aware encoding, artificial intelligence, and low-latency common media application format (CMAF). In addition, this article will present new concepts that can be deployed as part of an end-to-end OTT solution to further optimize quality of experience for OTT services on existing infrastructure [i.e., headend, content delivery network (CDN), and devices].

Available: https://medium.com/netflix-techblog/per-title-encode-optimization-7e99442b62a2As one can see in the table, legacy OTT services are far from having all of the tools to match the QoE provided by Netflix, while the advanced OTT services can not only compete with Netflix but also provide an experience that can be close to the broadcast experience for live services. Conclusion This article has reviewed different network architectures that provide a better QoE for ABR delivery. Encoding, especially CAE, is key to providing the best QoE. CMAF is an essential technology to reduce the ABR delivery end-to-end latency to a level close to what broadcast offers. CDN caching is an important factor, and client acceleration should also be considered. Finally, to optimize the network resources and avoid unfair client behavior, we advise operators to deploy a network optimization technology. All of those elements make us confident that, in the very near future, an ABR delivery mechanism can be close to a broadcast delivery network on a managed network. On an unmanaged network, it would be more of a challenge, as several parameters are out of the control of the OTT service provider. EXTERNAL
