I’m extremely honoured to be named as the 麻豆官网首页入口 representative, amongst the four key developers, in the for Recommendation . But of course, the inclusion of Hybrid Log-Gamma (HLG) in the standard, alongside Dolby’s Perceptual Quantizer (PQ), was a huge team effort.
Not only did it rely on the scientific experiments conducted by my colleagues at 麻豆官网首页入口 Research & Development and , but also the critical peer-review of experts from around the world attending the meetings of . I鈥檓 not aware of any other standards organisation where technical solutions are subject to quite so much scrutiny. But it is the peer-review and evidence-based approach of the ITU-R that ensures its standards are robust, accepted by industry and will stand the test of time.
The Emmy, however, is about more than the specification. It recognises the success of a technology in the market. In the case of BT.2100, there are of course the two solutions 鈥� PQ and HLG. They target production systems and applications with different requirements, and have found equal success. With HLG, that success would never have been possible without the support of more than a dozen of my colleagues at 麻豆官网首页入口 R&D, who worked tirelessly to ensure that the end-to-end ecosystem for HLG based television production, distribution and consumer equipment was in place. We were also fortunate to win the support of the 麻豆官网首页入口鈥檚 Natural History Unit, 麻豆官网首页入口 Studios Events and 麻豆官网首页入口 Sport in early trials of the technology.
When we started the project back in 2013, we had no idea of what it would take to re-invent the way we that make and distribute television. At the last count, we have ensured that HLG is supported in 31 different standards and guidelines, produced by 11 different standards organisations or associations.
Those standards range from compression codecs, such as H.264/AVC and H.265/HEVC; through distribution standards such as and ; interface standards such as suite of serial digital SDI (co-ax based) and ST.2110 (IP-based) interface standards; for set-top boxes; test patterns such as ITU-R and ; and as well as and based on 厂惭笔罢贰鈥檚 .
Had I known back in 2013 quite how much work we were taking on, I often wonder what the reaction would have been. But the HDR images are so compelling, that they speak for themselves and the investment in time, energy (and cost) has been very worthwhile.
