You are confusing modulation (DVB-T vs T2, DVB-S vs S2) where a mux/transponder is one thing or the other, with video coding (MPEG-" vs AVC vs HEVC) where you can mix (subject to the receivers being able to decode it of course).

Hang on, you were talking about YouTube. YouTube is not using 2020 colour. FWIW currently available TVs do not support 2020 colour either. It's still a Rec.709 world.

Cheers,

Because the vast majority of viewers couldn't care less about HD, that's why. They have HD sets because that's all you can buy these days - and they watch SD TV on them.

The only BARB separated HD channel figures I can see are for ITV HD, and the weekly viewing in June was... 10% of all ITV (1) viewing. That's how much most people care about it and the SD broadcasters know it, so can continue to push out low quality SD at minimal cost without losing many viewers at all.

I say again, most people don't care about watching HD and will care even less about watching UHD even if they end up owning UHD capable sets. Content is King and will always trump technical quality in the mass-market.

Ah OK. Good point. So it is possible then to have SD and 4K co-existing from a broadcast perspective. I guess that gives so excuse for minor channels not broadcasting 4K / 8K to continue to broadcast in SD although I would strongly argue that there comes a time when standards need to be changed and change needs to be forced on broadcasters for the greater good in the long term.

I appreciate what you're saying David. Watch it on youtube and you're viewing at 1080P or your monitor resolution at best and whatever colour space they both support. However, look at video of a tv showing HD and then look at video of a tv showing 4K / 8K. Even though you're not viewing at 4k / 8K specification, the superior picture quality can still be seen in the video of the tv.

What I would suggest is the vast majority of viewers watch what's easiest and they don't want to be searching the epg for obscure channel numbers.

Even I watch more SD than HD. However, it's got nothing to do with not liking it and more to do with not be bothered to switch over. after switching on.

If the HD channels from the major broadcasters were switched over to 101-105, I think viewing figures would go through the roof.

See also my post above about the greater good. People don't always like change and to that end, sometimes it has to be forced eg digital switch over. I'm guessing without it the majority would still be liking analogue tv.

Given a choice they switch to HD transmissions. And it will be the same with 4K. I imagine that both BT and Sky want to be first with 4K Premier League delivery.

Saying that, it sounds like 2015 might be a big year for OLED TV.
Cost falls might be about to make them affordable to the general public.

I guess 1080p OLED may well will fill a price slot between 4K IPS screens and 1080p IPS.
And without 4K maybe even 1080p OLED will be an option at 4K price .
