Ofcom has given a presentation for analysts that they've streamed on
t'net, and about 25 minutes of it (starting at about 40-45 minutes
into the presentation) is about Digital Dividend Review and the DTT
spectrum and so forth, and they said that by using DVB-T2,
statistical multiplexing (they called that a new technology, not
sure why), "mode change" (i.e. the use of 8K) and MPEG-4 video they
think that they'll be able to fit 4 HD channels onto existing DTT
multiplexes and they'll be "universally available" (I think they
used those words).

Yer, and that means all the current STBs will be obsolete, all the
current DTT tuners will be obsolete


No, standard-definition MPEG-2 TV channels will continue broadcasting, so

ON WHAT?

how will current STBs become obsolete?

Because the only way to fit in 4 HD channels into the existing multiplexes and be able to keep about a quarter of the existing Freeview channels is to broadcast the whole lot in MPEG-4, probably at very low bit-rates.



and there will be no room for all
the existing DTT channles.


No, all existing DTT channels will be able to continue broadcasting.

No they wont. There isn't any space on the existing MUX's to keep them as MEPG-2.



Talk about the BBC and ITV miseladeing
their viewers.


No they haven't.

Yes they have. Blue Peter has been misleading its viewers about the cat's name and the British Comedy Awards will not be shown because of another rigged phone vote.



The broadcasting regulator itself has completely
mislead the entire pubic from the start.


No it hasn't.

Yes it has. MPEG-2 STB's will be obsolete at Digital Switchover and everyone will have to replace all their existing boxes and PVRs with MPEG-4 boxes and PVRs.
