Television has used the same color primaries and gamma for decades. The world of HDR and WCG has brought confusion due to multiple color spaces and gamma functions. In this webinar, IABM’s CTO, Stan Moote, grills SRI Sarnoff’s Norm Hurst on what you need to know on both the production and the technical side.
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.

HDR has moved from technology innovation to mainstream deployment. This session reviews the basics of HDR and current market status.
This article is from The IABM Business Intelligence Digest from April 2018. The full report can be viewed here We examine specific trends driving broadcast and media technology spending in North America. The trends we discuss are: - Transition to Digital and HD Broadcasting - New Viewing Experiences (UHD and VR) - OTT and Multi-Platform Delivery - ATSC 3.0 The transitions to digital and HD broadcasting are mature trends in this region and do not represent significant spending drivers for vendors. The transitions to new viewing experiences, multi-platform delivery and ATSC 3.0 are instead now the principal spurs. Transition to Digital and HD Broadcasting In North America, the transition to digital broadcasting has almost reached maturity and therefore does not represent a significant driver of broadcast and media technology spending.

The requirement was set for full-power TV stations to shut down their analog transmissions by June 2009. Low-power TV stations were given an extended deadline of September 2015 and continued to broadcast in analog. However, the FCC suspended this deadline due to the Incentive Auction, which required the repacking...
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...
This article is from The IABM Business Intelligence Digest from September 2018. The full report can be viewed here State of Adoption – UHD & VR According to IABM data, UHD adoption has grown slowly in recent years, from the 14% reported at NAB Show 2018 to the 20% reported at IBC2018. Deployments have risen although there is still a high percentage of companies unlikely to launch any UHD offerings. Most UHD offerings have focused on sports content. Broadcasters now prefer IP or hybrid SDI-IP deployments for launching UHD services. With regards to compression standards, HEVC has become the most preferred for UHD delivery. IABM data shows that broadcasters prefer launching 4K (or HD) with enhancements rather than launching 4K offerings only. With regards to enhancements, HDR is by far the most preferred format. VR adoption has not significantly increased in recent years. As mentioned earlier, low consumer take-up coupled with high complexity and cost have all contributed to stifling adoption by broadcasters and other end-users. As we will show in the next section, the main VR deployments have been in sports. One of the reasons behind the low adoption of VR is the lack of certainty around the business...

Reflecting on the last year, it has been one of amazing change and contrast for broadcast and media end-users across the APAC region. South Korea became the first country in the world to transmit UHD over the air using ATSC 3.0 – ahead of even the USA. The march towards UHD in Japan, South Korea and, to a certain extent, China is real and now.
APAC region update: From the icy Winter Games, to the white heat of the Indian cricket summer, UHD is taking off!
