bruce: There isn't any capacity available to make the additional temporary red button channels available to SD-only receivers (which can't really considered to be the majority of viewers any more). The only space available is on the temporary COM8 multiplex which (along with COM7) is broadcast from 30 transmitters covering around 70% of UK households. SD-only Freeview boxes/TVs haven't been available for a couple of years now and it was reported around the same time that over 50% of viewers has access to HD channels on at least their main TV (that figure will have only increased since).

Nah, don't waste your money on a box, treat yourself and the boss to a 4K UHD capable set (at least 43") - I'm assuming you've got a half decent broadband connection with unlimited usage. The Beeb have been streaming some 4K now and again, and if you want to subscribe to some of the "other services", other things are available in 4K as well ;)

To get the UHD services Chris.SE is mentioning you need a broadband service of at least 24 Mbps and unlimited usage.
If that level of broadband is not available where you live, it's just not available in many rural or even some suburban afreas, then the box suggested by StevensOnln1 would be worth considering.
BTW, you will need quite a large room to accommodate a 43" TV set without sittij=ng too close to it for ergonomic comfort.

I'm afraid I find MikeP's comments a trifle misleading.
IF you are going to consider investing in a new TV, THEN get yourself a 4K UHD set - you will then be reasonably future proof as 4K programme availability is going to increase significantly in a reasonably short period of time.
The speed of broadband connection that you need for 4K will depend on whether it is an "on-demand" service that you want to watch, or a "live transmission", or indeed material that you download to save and watch later. You can have a much slower connection for the latter.
Unlimited usage is certainly a good idea if you are going to stream much TV, however most broadband packages these days are unlimited usage. Ideally you do need at least 23Mbps for "on-demand in 4K", and typically 36Mbps for a "live transmission" at present.
You might find this BBC blog of interest -
Making Blue Planet II available in UHD & HDR on BBC iPlayer - BBC R&D
This recent article is also quite interesting -
6 key facts about BBC's 4K iPlayer World Cup broadcasts | What Hi-Fi?
I noted this remark as very useful -
"The argument that arose during the Blue Planet II trial centred around viewers' need for 23Mbps or so to stream in 4K HDR while a 4K TV could still stream better resolution, wide colour gamut and HLG high dynamic range even with a slower internet speed."
Also, for standard HD streaming around 5Mbps is adequate.
I'm sure you could find a few more articles by using your favourite search engine.
As for room size and viewing distance, the suggested distances are in fact closer for HD (and so UHD) content than bog-standard SD. Typically around 5ft - 9ft for a screen of about 43", although of course you don't have to sit that close! You'll probably find a distance of around 8-10ft a good compromise for both SD and HD.
There's quite a good Wikipedia article about viewing distances -
Optimum HDTV viewing distance - Wikipedia
If you are used to a (much) smaller screen, in my experience, the difficulty most people I've found have, is simply getting used to the large(r) screen! (as well as a suitable "surface" to put it on}. Oh, and personally I wouldn't recommend the curved screens, but that's my opinion.
Enjoy whatever you decide.

to all who have replied to my enquiry, thank you.
referring to the HD set-top box, would appreciate advise. I have two HUMAX boxes that I have daisy chained. if I procure an HD box, could I add this to the chain and so receive HD programs?
thanks again bruce

Your proposed new HD box will receive all the available HD and SD channels, so the boxes do not need to be 'daisy chained' at all unless you want the additional recording abilties offered by having more than one box. With two or three boxes you could record more channels at the same time and have more recording space to store more recordings.

The changes documented in the 'Change Over Time' section for Mendip did not happen in March 2018.
Have these changes been scrapped or just delayed.
Thank you
