Channel television network contributions

I think, by the 90s, there were so many channels, some with regional ads, some with macro ads etc, some national it was much safer for advertisers to just use 'catch all' disclaimers on all copies.

You could often tell some ad companies that were test marketing products in certain areas only. I recall seeing captions like 'Not available in Anglia and Tyne Tees regions'.

I'm intrigued to know if any Channel programmes were also broadcast by Westward but not networked. If any were then would they most likely have been played out by Westward then broadcast to the Channel Islands or would they have been played out separately by both Westward and Channel?

Still common for Northern Ireland apparently. It turned up as a question on LBC's 'Mystery Hour' the other week:

The technicalities are also quite boring now, since ITV moved them to their new home in Castle Quay they're now on the same IP video network as every other ITV site. As for playout, Castle Quay doesn't have playout facilities so that must have been handed over to Red Bee, likely Chiswick.

No play-out, but I wonder if there is a resilient facility for ITV Channel to feed the tx directly, say if some disaster had knocked out network connectivity to Jersey?

Under normal conditions, this would be a no-go, as the CI D3&4 mux will be built on the mainland. But say there was no D3&4 mux, could there be a simple code chain just for an emergency broadcast? Presumably not, with Jersey / Guernsey emergency planning scenarios relying on radio......

The same applies to any mainland main transmitter for BBC or ITV too. They are all fed with diverse fibre feeds, and D-Sat back up (at least the latter for PSB 1 and 3 muxes), so I can't imagine Fremont is any different (other than perhaps one fibre feed coming via France ?)

I think Ted is asking whether there might be a facility for Channel to feed Fremont directly - I guess BBC style opting out of the DSat backup - as they are perhaps more vulnerable to ships' anchor type issues.

Although the normal mux will be built on the mainland, there must be the facility at Fremont to assemble a mux from the DSat backup, which is not pre muxed AIUI.

I doubt the back up arrangements are any more (or less) elaborate than for mainland transmitters, unless the CI governments have requested any specific resilience ?

I guess it's down to balancing the likelihood of the fibre getting cut and taking an extended period to fix aginst the consequences of Channel Report and local advertising not being able to get on air.

The former is unlikely to go down well with OFCOM, and could theoretically lead to a fine, so there might be some benefit to having a plan B ready to go.

Well yes, hence the diverse fibre feeds from diferent directions.

As far as I'm aware, no PSB 2 channels have D-Sat back up, and even for PSB1 is only the BBC Nations and not BBC regions that are backed up.

Yeah it must be bbc nations at 27.5w can’t see any regions on there.

I hadn't realised there were multiple fibre routes into Jersey given how long it took to get the first one!

I guess if a transmitter does fall onto the backup it would be possible for the BBC One feed on that satellite back up to be replaced by the appropriate region in certain circumstances.
