Default 4k TV on Freesat or Freeview?

4K TVs are becoming available and more reasonable prices and there are
some 4k internet streaming channels.

So when, if ever, will any of the Freesat or Freeview channels convert
to 4K?

Hi
I thought 4K TV was being supplied via the internet.

Regards
David

Sky is apparently launching a new 4K and/or UHD compatible SkyQ box later
this year and has plenty of satellite bandwidth to cope with the higher (up
four times HD) demands of UHD (remember how the BBC and Sky conjured up 20
or more new HD channels for the last Olympics).

The BBC did UHD test transmissions using DVB-T2 from three main
transmitters last year, but has been giving up it's satellite transponders
to save money, so seems unlikely to want to offer free to air UHD in the
near future.

So I'd guess the only free to air UHD will be state subsidised European and
Arabic broadcasters, and a German shopping channel.

worth waiting before buying a tv though.
if sky uses 120fps for their broadcasts as rumoured there's probably
nothing on sale now that will show them at their best.

Yes, I think it is necessary to wait a couple of years. From what I have
read, some of the present TVs blur motion pictures.

I would rather receive by satellite rather than broadband as there are
less contention problems.

Wait if you can, but if your TV breaks down, then the additional cost of 4K will provide more future proofing.

4K ....over Freeview?
One hopes you are 'having a laugh'. Seriously.

Consider that this stuff originates at 12Gb/s.
Tweleve gigabits of data, per second.
In comparison, present HD originates at just under 1.5Gb/s.

And to compress this enough so that its transmittable over freeview, you
would have to dispense with so much information that you would render 'UHD'
pointless.
i.e. The loss in quality would be so bad that it would be comparable to
existing HD. Therefore, just what is the point?

The only way to transmit 'acceptable' UHD is either usings serveral channel
spaces over satellite, or proper* broadband.
* meaning something better than BTs standard twisted pair phone line. Either
the co-ax that Virgin is installing, or fibre from both BT and Virgin.

4K over Freeview?
Hopefully, never.

UHD is certainly no more than four times the bandwidth of 1080i, which is broadcast in the teens of Mbps (SD usually less than half that).

With more sophisticated compression BT expect to be able to get UHD down a 30-40Mbps pipe, which curiously enough is what you normally get from FTTC. This will also fit onto a single satellite transponder. These currently carry up to ten SD channels or two to three HD ones.

Different argument for Freeview, although Freeview HD looks good.

Your version of "normally" might not apply to all FTTC users.
