It's worth noting that ITV HD still isn't on the Sky EPG
in the Channel Islands, although it can of course be manually tuned, so I suspect there's more to this than them simply not reversing the stripping of ITV HD from the PSB 3 PAT/SDT SI tables.
My guess would be there's something carried on the English regions that they can't legally broadcast in the islands, likely the adverts as many of the advertised products and services won't be available in the islands.
Clearly they've taken the decision not to launch a regional variant of ITV HD for the islands yet, presumably as it's not cost effective as London Lite suggests, so they've had to drop the channel entirely rather than opt for the nearest English region like they do for the rest of the country.
Didn’t Channel Islands move to a new facility a few years ago? I assume it’s all HD? Don’t know why they wouldn’t launch it HD. But then again from what I’ve heard ITV doesn’t want to launch more than what they have unless the BBC splits with them.
Yes the new facility is operating in HD, and I suspect playout is as well given that Channel is played out from ITV Pres in London, which is entirely HD for all the other regions.
The issue will be ongoing dispute with the BBC regarding who pays for new infrastructure for PSB 3, which has resulted in most the country receiving the wrong region on ITV HD. ITV point viewers who are looking for the right region to Sky/Freesat, but given the small population for the islands it likely isn't yet cost effective to uplink ITV HD for them.
So the PIDs 201,202,203 etc. for the video and audio etc. for the ITV HD service are there in the transport stream, but there is just no entry in the SI Service Information table? So in theory you can receive ITV HD if you can create your own SI data and have the skills to do so. I'd have assumed they'd have replaced the PIDs with null packets.
They've gone for the cheap and easy option. Replacing those PIDs with null packets costs more as it would require a multiplexer specifically for the islands. Dropping it from the SI is easier as that infrastructure is already in place for all the muxes nationwide, as Digital UK/Arqiva insert regional SI data on to each mux at each transmitter.
