摘要

A variety of over-the-top (OTT) adaptive mediastreaming formats exist (e.g. MPEG DASH, HLS etc.), whichincreases complexity when distributing media to as manydevices as possible. Support for content protection increasescomplexity for content providers even more, because deviceplatforms support different DRM systems.We present an overview of current streaming technologiesand propose a workflow to deliver live and on-demand OTTvideo content (including UHD) in an interoperable andefficient manner. Standards such as CENC (CommonEncryption) improve interoperability with regard to DRM.With the introduction of HTML5 Video a cross-platformalternative to third-party plugins (e.g. Flash or Silverlight)emerged. It allows video players and applications to becomeinteroperable. Content providers have to consider themultitude of devices available today, ranging from smartphones to smart TVs – all of these devices are used for videostreaming. We will evaluate streaming and contentprotection capabilities for various device form factors andrecommend a commercial OTT media delivery strategy.
