Re: 4K?
I sampled the delights of the NHK theatre at the National Association of Broadcasters (NAB) show last month. UHD2, 22.2 surround sound, with material that featured nature scenes, ballet, and quite stunning views of Tokyo by day and night. Screen was around 350 inch diagonal, so best of luck with a 50 inch home setup.
Impressive indeed: but even the UHD1 (NOT 4k, UHD is 3840x2160, 4k is typically 4096x2160) HDR being discussed here needs:
- to be delivered via a properly signalled compressed format
- to a decoder that understands that signalling
- connected to a screen that displays correctly - and is adjusted properly for colour gamut etc
It saddens me (as someone who has worked in broadcast for ~26 years) to say that the happy conjunction of all of the above is somewhat unlikely in the average home setup...
