Viewers are seeking a broadcast experience which more closely emulates the real world. Broadcast Manufactures have improved picture quality changing analogue to digital. We also have seen increased resolutions however there is still be a missing element. The missing element, realistic colour and contrast which better emulates the human eye. Broadcast technology and displays have limited colour and contrast ranges based on transmission technologies which have gone largely unchanged since the 1950’s.
Today however this has changed and there is opportunity to harness High Dynamic Range (HDR) and Wide Colour Gamut (WCG) on existing SDR transmission and HDR transmissions. Utilizing SL-HDR1 incorporating both static and dynamic metadata it is possible in both UHD and HD to deliver a single SDR signal and view on SDR as well as reconstruct full HDR for HDR devices. The single signal allows particularly Asian Broadcasters in HD to deliver the richest colours and highest contrast video to their viewers without increasing transmission costs. This efficient delivery enables broadcasters to deploy HDR today.

This article originally appeared in the IABM Journal, issue 100 which is available to view online here Ever since the introduction of ALEXA in 2010, ARRI cameras have been equipped to offer the best overall image quality and production value for HDR capture and display. HDR (High Dynamic Range) display technologies for cinemas and private homes are evolving rapidly, bringing vast improvements to image quality and richness. However, technical standards and workflows for creating and delivering HDR content have yet to be established. ARRI has been pushing the boundaries of high dynamic range digital imaging since the development of the ARRILASER and ARRISCAN, and is involved in the ongoing discussions that could see HDR become an important storytelling tool for filmmakers. With HDR still in its early days, there is much confusion and misinformation across the industry. Amidst this, an increasing number of productions that already create HDR deliverables – such as the Amazon streaming TV series Patriot, The Man in the High Castle, Mozart in the Jungle and The Grand Tour – are turning to ARRI cameras, which have offered unsurpassed dynamic range since the launch of ALEXA. What is the difference between HDR capture and HDR display? While...
