I saw it on WH this morning and just assumed it was the QSY LF to
make room for LTE.

....which means in English?

For the rest of us
QSY = Shall I change to transmission on another frequency?
A. Change to transmission on another frequency (or on ... kHz (or MHz)).

Channel 61/62 clearance

http://www.digitaluk.co.uk/industry/...hire_tv_region
I was surprised to see it on Emley Moor, which isn't affected.
Why didn't they list the small areas that would be affected?
Seems very lazy. If you keep warning people about something
that doesn't happen they start to ignore your warnings, which
might be valid.

Remember Emley has a lot of relays some of which are changing
although Emley itself is not - plus sub-main sites like Keighley
(which is changing) and its relays also. They are being done on
the same day as Winter Hill and its relays. Unfortunately the
cost of fitting kit at every affected site for caption insertion
and the means to switch it on/off or change it would be
prohibitive - it is easier to stick it on Emley and everyone sees
it, affected or not.

As WH is changing one of its channels, every relay has to have
at least one Rx channel changed, and some of the Tx's as well. Tx
power budgets have also been recalculated and some sites are
having power changes done at the same time - but worry ye not
some are only by 0.1dB at the Tx output (don't ask - I don't
understand why either!)

Don't think this will be the last of it either. I see today that
after this clearance (for the sake of 4G - ggrrr!!!!) the next
move will be to clear the 700MHz band so that additional muxes
can be put in place for national and/or local TV. Why HMG did not
make the decision to go SFN nationwide in the first place beats
me.

As someone suggested last week, how long now before the decision
is made to give everyone a sat system and turn terrestrial TV off
so that the mobile phone SP's can have the lot?

Ah yes, easier. The way everything has to be done nowadays. But would it
have been significantly less easy for the message to list in brief the
affected areas?

The more detailed info from digitaluk says the MHEGs should only have
been on Keighley and its relays, not Emley itself

But that was exactly my point. If Keighley was to radiate the
text box it would need caption generators for all six muxes at
the site with the necessary means of communication to be able to
control them and amend the text and those means of communication
may not exist as such. Installing such comms links all adds to
cost - and remember that clearance is being paid for by OfCom.
Insert the captions from a main station - where the robust comms
links do exist - is significantly easier and cheaper.

I would agree with your point entirely but for two factors: (a)
it is very easy for those of us in the business to see it but you
would be surprised how few people know which transmitter they are
using (not to mention those on communal feeds,) so telling them
which areas are being affected would have little meaning to most
of them and (b) even in any given area there will be people who
get their signals from unaffected transmitters and who will thus
be - shall we say - confused when it doesn't happen to them. Much
easier to tell everyone and let them work it out for themselves.

No, it is possible that the MHEG caption is only triggered off and
displayed if a set of defined criteria match, primarily the received UHF
frequency.
That's exactly what was done when half a dozen or so Caldbeck relays
moved muxes last year.
The MHEG caption was added at the BBC and D3/4 Muxing centres, on the outgoing
Caldbeck transport streams, but was only visible on the affected relays.

Of course it relies on the receivers being fully compliant, so
as to:-

a: Not to appear regardless of transmitter,
b: To pop up only on the appropriate transmitters !

But include a list of the affected areas.

If they'd said 'some viewers in the Keighley area' it would have been
better.
