Following IBC 2016, 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”
Note that this meeting was over half full on 1 September - Priority is being given to SMPTE members -
and became full on 6 September.
please use wait list .... But this is a very popular topic ..... And will be covered in different ways across the UK.
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.
Chaired by Andy Quested who chairs the ITU HDR Group
We will hear compelling explanations from
Prinyar Boon from Dolby on Dolby Vision, which is PQ/Display Reference based
and Tim Borer/Andy Cotton from BBC on HLG/Scene Referenced systems
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 network with others across our industries and beyond- formal meeting starts 19h00
SMPTE UK Thanks itv for the venue and to SMPTE UK supports for the ample refreshments.
