6 Mark Schubin, HPA Tech Retreat, 2014 February 206 EBU at HPA 2013 - 56” Screen “4K”@60 fps = 8x uncompressed data rate of either 720p60 or 1080i30

7 Mark Schubin, HPA Tech Retreat, 2014 February 207 EBU at IBC 2013  approx. full-gradeincreaseperdoubling of frame rate for chosencontent: 2x data per grade  w/ “4k” = 16x rate

8 Mark Schubin, HPA Tech Retreat, 2014 February 208 Source Material Matters

9 Mark Schubin, HPA Tech Retreat, 2014 February 209 HDR “A ‘4k’ display delivers the best HD you’ve ever seen” “A ‘4k’ display delivers the best HD you’ve ever seen” report on “The Great Debate”

10 Mark Schubin, HPA Tech Retreat, 2014 February 2010 HDR “A ‘4k’ display delivers the best HD you’ve ever seen” ARRI side-by-side Alexa demo HDR HD and 4K displays; quoted person agreed that HDR HD looked better “A ‘4k’ display delivers the best HD you’ve ever seen” ARRI side-by-side Alexa demo HDR HD and 4K displays; quoted person agreed that HDR HD looked better HDR can increase picture detail (reduced clipping) HDR can increase picture detail (reduced clipping) consumer TVs already have more DR than reference monitors consumer TVs already have more DR than reference monitors Contrast contributes to “sharpness” Contrast contributes to “sharpness” higher resolution can result in reduced contrast higher resolution can result in reduced contrast

11 Mark Schubin, HPA Tech Retreat, 2014 February 2011 At Finer Detail Contrast Affects Sharpness More contrast resolution “sharpness”proportional to area or square of area under curve

12 Mark Schubin, HPA Tech Retreat, 2014 February 2012 True HDR Even More contrast resolution

14 Mark Schubin, HPA Tech Retreat, 2014 February 2014 HDR Data Rate Increase Theoretically: none Theoretically: none bit-depth simply determines SNR (~ 6 dB/bit) when at least ½-LSB is noise bit-depth simply determines SNR (~ 6 dB/bit) when at least ½-LSB is noise Practically: causes contouring Practically: causes contouring contouring halved per bit contouring halved per bit contouring eliminated when ½- LSB matches or less than noise contouring eliminated when ½- LSB matches or less than noise 12-bit over 10-bit = 0.2x rate 12-bit over 10-bit = 0.2x rate No EBU data released yet, but, if only 0.5-grade, 0.4x/grade No EBU data released yet, but, if only 0.5-grade, 0.4x/grade
