The DTT mux does not have Teletext subtitles in it as was required for analogue ..... but the DSAT does for Sky boxes ... hence the use of a DSAT feed .


Of course! That makes complete sense now!

The regions are fed ST 2022-6 SDI over IP both to and from the regional opt switch and then coded and muxed and then given to Arqiva at ASI who I think use ST2022-2 IP to the transmitter


Ah - when did the 9Mbs MPEG2 BBC One network distribution become deprecated - was that when coding moved from local DSat and DTT CBR encoders to backhaul for coding and mux, or was it when the Energis/C&W/Vodafone connectivity was replaced by BT? (The 2022-6/-2 stuff makes me think the latter?)

The same sort of applied to the Channel Islands. Though both ITV and C4 had switched to a 'proper' fibre circuit in the 90s, so were not affected by the SHF shortage. The D-Sat solution for BBC 1/2 lasted from 2003, to DSO in 2011


That was introduced while BBC CI's studio was still the converted garage at Fremont Point.

They went from the path from studio to TX being a few hundred metres to being fibre to London (via Plymouth) then a 44,000 mile round trip via the Clark belt

I’m confused wouldn’t rebroadcasting a feed designed for viewers in one format to another reduce the quality? From what it sounds like that briefly they took the one signal from Sky DSAT or FreeSat to feed the transmitter. I take it the quality from the satellite wouldn't be the full quality that it would be if it was microwaved to the transmitter.


No it certainly wasn't. Though, as I said up thread, when ITV/Arqiva did the same thing in the South West of England, they also increased the bit rate (and the resolution) of the satellite stream to make it a better quality source.

However, in the case of BBC East and ITV Westcountry it was only a temporary measure for a couple of years, to
keep the analogue feeds going until DSO. For any longer period, a more conventional arrangement involving microwave links and fibre circuits would have been implemented, but the costs didn't stack up for the sake of a couple of years. Both these schemes were provided, because in both cases the local studios had been relocated.

Apologies, I didn’t see your post. Just seemed like an odd way to feed a transmitter for a period of time and obviously took a while to get my head around.

In the context of what it replaced it makes a lot more sense

Yes. I can’t remember when did the TV operation move from the garage to Radio Jersey ? It must have been at or after the English regions launched on D-Sat, June 2003 ?

Just had a look at Look North Hull to see if they’d covered the launch of the LNER Azuma like Leeds did (they didn’t seem to) and I’m wondering how long have they had that opening sequence?

That non standard rotating red box during the headlines, with the oversized white headline font, and the fact that getting in touch is promoted almost as a main headline ahead of most of the actual headlines? Not to mention the fact two of the contact methods are phone numbers, two phone numbers for both Hull and Lincoln, like it’s a Children in Need appeal circa 1990?

Radio Humberside has two phone in numbers, Hull and Grimsby. I've always assumed it's some quirk of Kingston Communications rather than BT running the phone network there that made calls into Hull from outside expensive or similar.

It used to. But early last year it went to one 08000 number.

I think in the old days many local radio stations with more than one main town would have a local number. Of course Humberside as a county was never popular and so any attempt to engage people both north and south of the river would be seen as needed.

A few organizations had Hull and Grimsby numbers. The reason was the way that charge groups allowed local call access to adjacent groups.

Grimsby/Cleethorpes was isolated from Hull by the Immingham charge group sitting between them, so subs there got charged for a trunk call into Hull. Scunthorpe had local call access into Hull. Bridlington and Driffield were the other charge groups in Blunderside outside the Hull local call access area.

Nope, stories from Anglia/Look East are fine, but nothing from Leeds! Very Happy

Seem to have covered the zumey train today it today but of course they had to put a Lincoln slant on it.
