Adaptive Streaming's Primetime Challenge

Adaptive Streaming's Primetime Challenge | DRM video | Scoop.it

Video service providers have become enamored of adaptive bit rate streaming as a way to deliver video to tablets and smartphones, but not everyone believes the technology will become the primary way video is delivered to the home.

 

HTTP Adaptive Streaming (HAS) "is not ready for primetime TV," declared Pieter Liefooghe, chief solution architect and solution line manager at the video solutions and integration organization of Alcatel-Lucent, during a panel on the topic at last week's Managing & Monetizing OTT Video event in Boston. HAS is "okay for a single-stream, OTT-style of service, but as a basis of a primetime TV service, it's a challenging proposition," he added.

 

But this doesn't mean HAS will never be suitable for primetime TV, as the shortcomings identified by Liefooghe relate to "out-of-the-box" HAS technology. He said, for example, that AlcaLu has identified some technologies and techniques that can be done on the routing platform and the content delivery network (CDN) to boost HAS performance enough to address some of its technical shortcomings. And he insisted there are ways to pare delays down to six seconds while still guaranteeing continuous playback.

 

"There's a future for HAS as the new RTP," Liefooghe concluded.

HbbTV improved adaptive streaming

HbbTV improved adaptive streaming | DRM video | Scoop.it

The HbbTV (Hybrid Broadcast Broadband TV) consortium has announced the publication of version 1.5 of its hybrid TV specification. Building on existing standards and web technologies, the HbbTV specification provides the features and functionality required to deliver feature rich broadcast and internet TV services.

 

Version 1.5 of the HbbTV specification notably introduces support for HTTP adaptive streaming based on the recently published MPEG-DASH specification, improving the perceived quality of video presentation on busy or slow Internet connections. It also enables content providers to protect DASH delivered content with potentially multiple DRM technologies based on the MPEG CENC specification, improving efficiency in markets where more than one DRM technology will be used. Version 1.5 significantly enhances access to broadcast TV schedule information, enabling operators to produce full seven-day electronic programme guides as HbbTV applications that can be deployed across all HbbTV receivers to provide a consistent user experience. The latest advances are based on activity within the HD Forum in France as part of the development of the TNT 2.0 specification
