As well as Channel Television, I have often wondered it viewers in the Channel Islands can also receive Channel Four and Five and if they have been able to receive Channel Four for as long as 1982?
I know that many BBC (as discussed on anther thread) and ITV programmes are transmitted from the mainland and received at Fremont Point. Am I right in saying Meridian is the ITV region responsible for transmitting networked ITV programmes to the islands?
AIUI originally Westward was the off-air mainland ITV service that was off-air received and rebroadcast by Channel. Then in 1982 (I think) they switched to TVS as that was a more reliable feed for UHF off-air reception, and stuck with this transmitter source for Meridian. (Some overnight trails on TVS had "Not Channel Islands" on them as Channel TV only replaced breaks during the day - with TVS/Meridian ad-breaks going out overnight - and I believe TVS/Meridian shared the revenue from these breaks with Channel TV?)
When ITV launched on DSat a more reliable and better quality fibre feed was installed to feed Channel TV in Jersey, so they no longer had to rely on off-air rebroadcasting, and the fibre was also used to feed Channel TV back to London for uplink on one of the ITV transponders on one of the Astra 2 satellites. (ISTR that the fibre wasn't available initially, so the off-air feed was still used as the source, and an SNG truck was used to rebroadcast Channel TV to London for uplink)
However I believe that rather than a clean network feed, Channel still get a dirty Meridian feed, and if Channel don't opt-out of this, the Meridian feed is broadcast. (So Channel don't need to run a 24/7 operation - and now that ITV1 is effectively networked most of the time, this is far less of an issue than it once would have been)
(The BBC used to use an off-air rebroadcast arrangement - with the reception array on mainland France - Cherbourg? - and an SHF Microwave link was used to get this to Jersey. However the BBC transmitters are now fed via a standard BBC One CI DSat satellite off-air receiver, and the BBC One CI feed is created in Plymouth - with - last time I heard - the BBC Jersey studio output fed back to Plymouth - where the opt-out switch takes place - via a bunch of DSL circuits dedicated to this function - 4x2Mbs to give 8Mbs?)
