A number of HDR over 4K TV demos at IBC this year as High Dynamic Range as a way to cheaply and effectively enhance image quality and perception is receiving a larege amountb of attention. Ericsson took a different approach it showed HD with HDR, as an alternative to 4K.
Some first impressions. Not that one can judge differences easily, most demos are underbright light, involve engineering samples, and what one sees is a display.
Envivio was showing Dolby Vision (Oblivion, does that movie have anything but grey) in the middle of its booth under big lights.
Not sure what to expect though Thomson, also said something similar, so did ATEME. ATEME showed 45 Mbit/s HEVC encoded 4K HDR. Blu ray approved and more, content supplied to Sony for its booth demo. File based software transcoding, but no full workflow, just a display showing 4K HDR. Thomson, 'No here we are just showing the end result', after having announced a full contribution workflow, with a contribution encoder upgrade that should start shipping in Q2 2016. However Hispasat launched an HDR demochannel, using that prototype encoder, 25P Free to Air, require my notes for bitrates, reception is using a big pc with a DVBS2 demodulator card,4K graphicscard,i.e a proper demo.
Ericsson did show a live contribution over satellite. The project started a year ago, material was shot over this time. Video comes out of camera as HDR, the only tweak was to match brightness of the display, using a long discontinued Quantel box. 'Contribution', so not hindered by HDCP;-).
Of course Cineramax' friends at Civolution offers both watermarking during production through to screeners, as well as watermarking for set-top-boxes.
HDR content, HDR distribution, HDR display, should always well. Issues start to pop-up when you want to account for legacy infrastructure and legacy displays, most likely encountered in Broadcast, and IBC used to be called International Broadcasting Convention. When you want to supply content to both HDR capable and SDR displays. That is when the proprietary systems may offer great benefit. Of course these vendors claim their solutions are always superior even without the need for backward compatibility.
