HLG - Hybrid Log Gamma

Postby Paz_Pazzaz » Thu Feb 01, 2018 11:24 am ... it-2947378

I think I need a dictionary of acronyms!

HGL is a new one for me. Anyone have any thoughts about it?

Sometimes I think they invent the vocabulary faster than they invent the actual technology.

If you were going to buy a new HDTV that had HDR capability, you might want to get one that could support or be firmware upgraded to support HLG provided it didn't cost an arm and a leg to do so. HLG is definitely not a show stopper right now -- I haven't heard of anyone broadcasting HLG content yet. But, it will be coming.

HLG is designed to increase the dynamic range of live broadcasts and works mainly in the lighter portions of the picture. HLG content should be able to distinguish subtle tone difference in the highlights that otherwise would be burned out and indistinguishable. It's not the same as HDR. I would consider it a nice to have feature in the future, but not one that I would pay a substantial premium for today.
