3G蜂窝覆盖的扩展和更强大的移动的设备的出现增加了对大规模可扩展的移动的视频递送的需求。第三屏幕作为视频的主屏幕的快速采用突出了移动的交付生态系统中的低效率和移动的交付基础设施中的可扩展性问题。本文概述了当前的移动的内容交付生态系统，并讨论了基于HTTP的移动的视频交付的扩展作用。一类新的基于HTTP的移动的传输协议试图通过简化和标准化移动的视频传输来解决现有的质量和可扩展性问题。本文展示了基于段的交付如何实现基于HTTP的实时流媒体和动态比特率自适应，同时通过使用现有CDN基础设施提高可扩展性。
Expansion in 3G cellular coverage and the emergence of more powerful mobile devices has increased demand for massively scalable mobile video delivery. The rapid adoption of the third screen as a primary screen for video has highlighted inefficiencies in the mobile delivery ecosystem and scalability issues in the mobile delivery infrastructure. This article provides an overview of the current mobile content delivery ecosystem and discusses the expanding role of HTTP-based mobile video delivery. A new class of HTTP-based mobile delivery protocols seeks to address existing quality and scalability issues by simplifying and standardizing mobile video delivery. This article shows how segment-based delivery has enabled HTTP-based live streaming and dynamic bitrate adaptation while increasing scalability through the use of existing CDN infrastructure.
