Mike Angle: Google something like Channel 4 HD Wales.
I would imagine that the answer is likely to be no because if they did put C4HD (I would expect C4 will have to pay for it!) on in Wales, then the spare HD slot that is available will then not be UK-wide; i.e. it will exclude Wales.

Thanks for that. I now see that Ch4 HD is not available anywhere in Wales. The Freesat area checker is still claiming it is however.
I noticed a homophone in my post too late.

I am disappointed to find there is no English channe4HD in Wales. I switched to digital long before the switch over in my area so that I could get English channel 4 which I have enjoyed for many years,I cannot understand why this segragation is back in place. I moved to Wales but do not speak welsh, many Welsh people dontspeak welsh either, so I fail to see why we cannot receive the English channel4HD. Are there any plans to change this, or can I contact someone to voice my opinion. Thank You

Mr. J. White: S4C has the right to a HD slot in Wales, as the law provides for this and Ofcom have to implement the law.
If you want to watch Channel 4 HD you will need to use Freesat.

Mr J. White, Briantist: No, the BBC B capacity-reservation scheme is national, not regional. While "The Television Multiplex Services (Reservation of Digital Capacity) Order 2008" allows Ofcom to specify different areas of the British Islands in each application process, in practice they have so far only advertised for services covering the whole of the British Islands.
References: The Television Multiplex Services (Reservation of Digital Capacity) Order 2008 section 3(3)(b)(ii) and http://stakeholders.ofcom….pdf section 2.30.
In response to the first invitation to apply, Channel 4 made a joint application with S4C in which they agreed that S4C would serve Wales, and Channel 4 would serve the rest of the UK: http://stakeholders.ofcom….pdf . This is the legal basis on which Channel 4 HD and S4C Clirlun are running. S4C Clirlun does not, individually, have a Digital Television Programme Service licence - it is part of the Channel 4 HD DTPS licence. (DTPS and Digital Television Additional Services, DTAS, licences are listed at Ofcom | Digital TV Channels .)
Channel 4 were actually under no obligation to make this offer to S4C, they could have applied for a nationwide service. (Equally, so could S4C have applied for a nationwide service.) That is in contrast to ITV plc, who were effectively required to collaborate with STV plc, UTV Media plc and Channel Television, because the Order requires that any application from "Channel 3" companies represents at least 13 regional licensees. ITV plc owned (at the time) 11 regional licences and one national licence, STV plc owns two, UTV Media plc owns one, and Channel Television owned one. Since then, ITV plc have bought Channel Television, but that still leaves them one short.
In that first application, there were two slots available, and potentially four applicants: the ITV companies, Channel 4, S4C and Channel 5. C4 may have decided to invite S4C to join to improve the strength of their own application. The other companies were entitled to not just apply for an HD version of their traditional analogue service, but also for any new service, whether or not an HD version of any existing service, so had they been able to agree on it, the ITV companies could have submitted a second application to run ITV2 HD, for example.
Of course Channel 4 may have been 'encouraged' to offer the capacity to S4C, it may not have been entirely their choice!
I believe that if Channel 4 proposed to later drop S4C Clirlun, that would fall under section 19(3C) of the Broadcasting Act 1996 (inserted by section 7(3) of the Order). I think it's likely that Ofcom would decide that the variety of services was 'unduly diminished' - though I could be wrong, Ofcom have permitted Capital Radio and Heart to turn their accreted collections of independent local radio licences into national networks.
