Default New technologies?

Is there really a call for this sort of definition outside of very large
screen public use?

Right now we have a mix of standard definition (SD) and high definition
(HD). Currently marketed are 4K televisions with amazing images.

We can stream 4K from commercial sources provided we are prepared to pay
for
the fibre-optic connection and streaming source.

Is that it for broadcast TV or is there currently any research currently
seeking to squeeze more out of the available bands?


The BBC did a UHD trial (4K) for the previous world cup, including DVB-T2
transmission borrowing the COM8 muxes from Crystal Palace and Winter(?)
Hill before they were live.

There are a couple of UHD test channels on Astra 28.2E, and presumably Sky
has commercial channels, my DVB-S2 PCIe tuner found them OK

Also (for certain TVs) They tested a 4K stream of Blue Planet 2 on
iPlayer.

Given the number of muxes will be shrinking over the next few years as
phones grab more and more spectrum, I suppose it's unlikely there'll be
any terrestrial UHD services ...
