trevorjharris: I agree that the Public Service Broadcasters have an obligation to provide HD services but that isn't what I said.
My point was that the HD multiplex is a "PSB" and therefore available from all transmitters as a "Public Service" rather than the quasi-national Commercial (COM) networks.

trevorjharris: The first sentence should say that "I agree that the Public Service Broadcasters **do not** have an obligation to provide HD services, but I didn't say that they did."
The question h churchman was asking if the HD multiplex was available from a particular transmitter and the answer is "yes, it is available from all transmitters" and this is because it operates as a Public Service Broadcaster (PSB) network.

Denis Swingler: Perhaps it is your reception that has "downgraded" rather than the transmission.
Try some attenuation as it could be the signal level being too high and overwhelming your receiver:

Rachael: Are you sure that you are receiving ITV1 etc from Emley Moor and not Belmont or possibly Bilsdale?
The signal strength screen should say that it is tuned to C44 for Emley rather than C26 for Belmont or C29 for Bilsdale.
If it is tuned to Belmont or Bilsdale, you should be able to avoid them by having the aerial unplugged for the first 30% of the scan.
Also, Film4 should be tuned to C48.

Rachael: 44 is Emley Moor.
If it is on 26, then it tuned to Belmont and the unplugging aerial trick should work to avoid Belmont.

Gareth Jones: Perhaps knowledge of your TV or Freeview box would allow its user manual to be found so as to give instructions on what you need to do.
The changes at Llanddona meant that PSB3 (ITV1, S4C, C4 etc) and COM6 (Film4 etc) would have been lost as they changed frequencies.
For a full list of Freeview channels, see:
DTG :: DTT Services by Multiplex
This page has six tables, each of which is a carried as a single signal known as a multiplex.

Gerard Campbell: No. It is affected by the "Split NIT" issue:

The device was not built fully compliant with the DVB-T standard.

Martin: Do they all not have scart sockets on?
For example, the Humax HD-FOX T2 has a scart socket out and so will connect to a SD TV:

It would seem a sensible thing to get a Freeview HD PVR which will then allow you to record HD channels when you can view them when the time comes to change the TV.

h churchman: Yes, HD channels are broadcast by all transmitters as they are "Public Service" services.
