HDR more important than UHD resolution concludes poll
HDR beats out 8K
A recent poll conducted by TVBEurope.com determined that HDR was a more important factor than 4K or 8K resolutions for the broadcast industry, going forward.TVBEurope.com’s State of Play: 8K, UHD, HDR webinar included a poll asking the attendees to choose which technology they thought was more important to the industry right now.
The results came back and indicated that two thirds (66.7%) of the audience felt that HDR was currently a more significant technology.
The webinar discussion panel consisted of a range of industry experts and included; Thierry Fautier, President-Chair of the Ultra HD Forum, Andy Beale, Chief Engineer BT Sport and Gavin Ho, Technical Director Insight TV.
The wide-ranging topics up for discussion included the roadblocks to HDR, how the panel perceived 8K and how best to educate the consumer over all the different technologies that are involved in the simple act of watching a movie, football match or TV show.
In terms of the overall process of getting regular 4K sports broadcasts up and running, Andy Beale explained that it took some time to get all the required elements of HD, SDR, 4K and HDR all into one workflow. The aim was to deliver all requirements from a single Outside Broadcast station, thus streamlining the entire process and making it more cost effective. He further commented that the hardest part of the move from HD to 4K was the increased bandwidth and storage requirements which meant a whole new infrastructure was required to bring 4K sport to fans. However, the move to HDR creates a much smaller overhead now that the 10-bit, 12 Gigabit infrastructure is in place.
While the process of broadcasting HDR may have become easier more recently, one of the main issues facing the industry is the user’s own equipment used to receive and view the HDR signal. Thierry Fautier explained that his recent experience showed how different TV sets handled the HDR signal in a variety of unexpected ways and that using operator set-top boxes or an on-demand approach, such as the BBC iPlayer, might help improve the situation.
The panel also perceived the many HDR standards and specifications as a factor that confused the consumer. A recent survey in Germany showed only around 50% of consumers could explain what 4K resolution was and only 26% could do the same for HDR.
Beale noted that, despite the best efforts of UHD Forum with standardised logos and language, customers would still get confused over TV manufacturer's branding.
In terms of 8K, the panel agreed that the consumer electronics industry was driving the new standard up to a point, and that production and broadcasters were ‘playing catch up.’
While the emergence of 8K TV is still very much in its infancy all agreed that there were some useful benefits in currently capturing content at 8K including the ability to have high zoom factors to zone in on a small part of the 8K image and still have it in high-quality 4K or HD - useful for VR.
How have AVForums members found their experience of broadcast HDR? Would you agree with the poll findings that it is more valuable to the TV industry right now than increasing resolution up to 8K? Let us know in the discussion thread.
