HD Freeview on TV with a standard Freeview tuner

Once there will be HD Freeview channels transmitting in my area will I be
able to watch these channels on TV with standard Freeview tuner, albeit in
standard definition?

Yes if the station broadcasts in both SD and HD.

No. A standard (non-HD) Freeview tuner cannot take an incoming HD
broadcast and convert it to SD.

SD is broadcast using the DVB-T standard. HD uses the DVB-T2 standard.
An SD Freeview box can handle only DVB-T (SD) material. It will ignore
DVB-T2 (HD) stuff. It has no means of "decoding" it.

You are confusing two issue here -- tuning and decoding.

A standard SD Freeview receiver does ignores the DVB-t2 transmissions
because it cannot receive the DVB-t2 format of the transmission.

It is only after the signal has been processed by the tuner that the
HD multiplex video stream encoded in MPEG-4 (h.264 codec) is decoded.

So to summarize:

Freeview SD is DVB-t transmission with MPEG-2 encoding.

Freeview HD is DVB-t2 transmission with MPEG-4 encoding.

Other European countries current broadcast terrestrial HDTV with DVB-t
transmission but MPEG-4 encoding.

Saorview uses this format for both SD and HD transmissions.

I carefully put the word decoding in scare quotes to indicate that it
was not being used with exact precision.

True, but a particular program might well be in SD on BBC2, 3 or 4 at the
same time, or on another BBC station at a different time/day.

And when they switch off the DVD-T tranmissions we'll all have to
chuck away all those STBs. There's progress.

It keeps people in jobs making new ones.

It is somewhat alarming. If we were, as individuals and as a society, to
cut back on purchases that are not strictly necessary to life there
would be mass unemployment worldwide.
