Sapporo JCT-VC and MPEG Meetings - Jun/Jul 2014

Sapporo JCT-VC and MPEG Meetings - Jun/Jul 2014 | Video Breakthroughs | Scoop.it

NGCodec was at the JCT-VC/MPEG Meeting in Sapporo to help the industry to continue with the development of the HEVC standard. This was a busy meeting where we did substantial work over 9 days. JCT-VC finished the work on the 2nd version of the HEVC text covering the enhancements related to scalability (SHVC), completed the work on HEVC Test Model (HM15) software and text, the version 1 conformance and accelerated the work in relation to the coding of screen content (SCC). They were a number of additional MPEG activities that were conducted outside JCT-VC, mostly in relation to High Dynamic Range video (HDR) and royalty free codecs.

SMPTE backs “dazzling” HDR spec

The Society of Motion Picture and Television Engineers (SMPTE) on September 10 is to release a technical standard covering High Dynamic Range (HDR) images that will – in essence – match the Dolby Vision proposals from Dolby Labs.


The concept could allow viewers to see what has been described as “dazzling” in its treatment of whiter whites and permitting much more variation in representing blacks/grays and items in shadow.

One commentator, The Hollywood Reporter’s Carolyn Giardina, says early demonstrations have shown that the difference is a “more noticeable upgrade compared to moving from HDTV to Ultra-HD”.


The September 10 meeting at IBC will see SMPTE publish its ‘transfer function’ document which outlines a roadmap for the technology, starting at the camera’s lens and on to colour grading and post-production and eventual delivery to broadcasters and the home.

University researchers make real-time HDR encoding & streaming a reality

University researchers make real-time HDR encoding & streaming a reality | Video Breakthroughs | Scoop.it

Researchers have pushed the boundaries of High Dynamic Range (HDR) video to match our own eyes’ ability to cope with the real world's ever rapidly changing light intensity, such as sun simply going behind clouds.

 

Now researchers at WMG at the University of Warwick (U.K.), have found a way to compress and stream HDR video directly to monitors and mobile devices, such as an iPad.

Nicolas Weil's insight:

Still a lot of controversy on HDR benefits floating around, nevertheless an interesting research topic...
