Following NAB 2017, we take a look at HDR with key proponents of both PQ and HLG technologies
To see which best fits the needs of the Television and Cinema industries-
what is each systems trying to achieve and is there a place for both?

With the rapid take-up of high dynamic range and wide colour gamut in production,
and the increasing availability of TV Sets and Cinema Projectors capable of displaying
these superb images faithfully, we need to standardise and deploy systems that satisfy:

  • Compatibility with existing TV Systems, where necessary
  • Best use of the bit-depth available without suffering artifacts (Barten Ramp)
  • Viable conversion between formats, as part of the “HDR Ecosystem”

There was a similar meeting after IBC at itv on 22 September 2016

With two leading standards: Perceptual Quantisation and Hybrid Log Gamma,
both excellent in their own rights at delivering perfect pictures to the screen,
we have to delve into the delivery of those pictures and the simple practicality
in both Cinematic and Domestic display.

After a brief introduction from Andy Quested  who chairs the ITU HDR Group

We will hear compelling explanations and updates  from
Prinyar Boon from Dolby on Dolby Vision, which is PQ/Display Reference based 
and Tim Borer/  from the BBC on HLG/Scene Referenced systems

and then ample time to question and discuss under the careful chairmanship
of Chris Johns Chief Engineer Broadcast Strategy SKY

A description  of both PQ and HLR is given in
ITU-R BT.2390 “High dynamic range television for production and international programme exchange”
and in ITU_R BT 2100 : Image parameter values for high dynamic range television for use
in production and international programme exchange (previously known as ITU-R BT[HDR])

Come and meet others from across our industries and beyond - Formal meeting starts 19h00
SMPTE UK Thanks s-a-m for providing the venue and ample refreshments
