Adaptive Bitrate Streaming Gets Serious in 2012

Adaptive Bitrate Streaming Gets Serious in 2012 | Video Breakthroughs | Scoop.it

In a decade or so down the line, experts looking back likely will say that 2012 was the year cable operators and the rest of the telecommunications industry pivoted from basic “get it out there” multiscreen platforms to those that work with a far higher level of precision and efficiency.


That’s the plan, at least. What happens remains to be seen. What is clear is that the industry is poised to take several important steps beyond the “one off” catch-as-catch-can approach that has dominated to date. “The year 2011 saw most — if not all — the major service providers world-wide investigating adaptive streaming, ranging from lab investigations to highly publicized deployments,” wrote Yuval Fisher, chief technology officer of RGB Networks in response to emailed questions. “The market has matured quickly, with operators’ expectations quickly rising from the initial ‘help me just see how this works’ to ‘I need high video quality, high-availability equipment.’”

OVC 2011 Developer session : Standards for HTTP Adaptive Streaming

OVC 2011 Developer session : Standards for HTTP Adaptive Streaming | Video Breakthroughs | Scoop.it

One of the most popular features of modern Flash players is the ability to adapt the bitrate of the streamed video to the available bandwidth, also called HTTP adaptive streaming. HTML5 browsers (with the notable exception of Safari, which supports Live Streaming) do not yet suport this feature because it has not been standardised yet in a codec-independent manner.

 

ISO/MPEG have developed the DASH specification, which may be applied in a codec-independent manner and therefore be a good option for HTML5.

 

While there are several solutions for HTTP adaptive streaming of MPEG video, none has been released for WebM, nor a standard set that works across media formats.

 

Experiments have been run in several frameworks for WebM to see how it can work in comparison to MPEG. This session gives the developers an opportunity to report on their experiences and to discuss how to move forward for standardisation across browsers and codecs.
