  • IBC: SES, LG, and Hisense/Dolby show 4K HDR Broadcasts

    The LG demo featured the company's OLED display with peakwhites around 800 nits. And material supplied by LG, that confirmed to the SMPTE 2084 HDR curve, that is compulsory in the upcoming 4K Blu-ray standard where proprietary systems by Dolby, Philips and technolicolor is optional.

    The Dolby Vision demo used a Hisense LCD set,and featured material produced/commisioned by SES, of a baletdancer and stickfighter, we saw in other Dolby Vision and 4K TV demo's at other booths. Unfortunately all the curved HDR Dolby Vision panels with the purple and yellow demoreel sported a great amount of noise. At SES they used 19 Mbit/s for the base layer and 6 Mbit/s for the HDR enhancement layer, as Dolby Vision uses two MPEG HEVC streams to recreate the HDR signal. There was also the same material running at a lower bit rate 3 Mbit/s for the enhancement layer, but I would need to retrace my notes to identify the company and demo.

    Broadcast via SES?s prime orbital slot of 19.2 degrees East, the content will showcase two features that will further enhance Ultra HD: High Dynamic Range (HDR) and Wide Colour Gamut (WCG). These two features will bring more contrast and a larger palette of colours, respectively.

    Together with LG Electronics, SES is broadcasting a live demo of UHD HDR using the SMPTE 2084 (HDR) and BT.2020 (WCG) standards, and will display the content on an LG UHD OLED display at the IBC. The same demo was also shown at IFA 2015.

    LG initially worked with BBC's Hybrid Gamma, the EOTF/OETF (Electronic Optical/Opto-electrical Transfer Function), but later suppplied material using the SMPTE standard 2084. The BBC has come together with NHK that worked on a similar HDR curve system to offer a joint system. Hardware vendors struggle with licensing costs for proprietary HDR offers, as long as it is all in flux and there is no resolution to wich (proprietary, licensable) HDR encoding is the norm, they cannot afford to include multiple systems, so SMPTE 2084 becomes more attractive for the time being.

    SES is also partnering with Dolby Laboratories to broadcast Ultra HD content using Dolby Vision HDR, which is backwards compatible with existing UHD 1 Phase 1 TVs i.e 4K TV's probably with 8 Bit/s panels and inputs that lack HDMi2.0a full bandwidth inpouts, and unable to display the pek white levels and deeper balck levels required for HDR, and hat are already in consumers' homes. I.e. Legacy infratructure and displays.

    SES and Samsung demonstrated the world?s first satellite broadcast of Ultra HD HDR at the annual SES Industry Days in May 2015, using the BBC Research & Development's backwards compatible hybrid gamma system. And the booth features two 88" Samsung 4K TVs.

    SES continues to be at the forefront of Ultra HD developments, together with industry partners, bringing Ultra HD to a higher level of viewing experience via satellite.
