This Morning

A fibre link to a Down The Line studio in Miami would have no significant delay... You see it quite a lot these days. Skype calls can be very low latency too

Most telecom circuits across the Atlantic (and everywhere else) are fibre these days. Far lower delay, and way way more bandwidth available than a satellite (or terrestrial microwave) link. That's why the BT Tower (and its siblings around the UK) has very few dishes (and those you do see, may not be in regular use)

You usually have just the codec delay with fibre connectivity - plus a bit of standards conversion if you are going from 59.94 to 50Hz. It's not instantaneous even with fibre, but it's usually pretty low latency. If you are willing to pay for higher bitrate, or accept lower picture quality, you can run your codecs in low-latency mode (which delivers lower picture quality for a given bitrate) to reduce delays further.

Yes - though codec delay is increasingly significant as longer GOPs and lower bitrates are used...

It looks like This Morning are using a dodgy 3G signal today for a live outside broadcast at the London Eye with The Speakmans.

Seems appropriate.

BBC London also used a ropey London Live style 3G/4G connection from the Chelsea Flower Show on Monday for a live and the weather forecast.

I'm surprised there's nothing more suitable for a link up to the South Bank.

The OB on the South Bank was in full HD today.

Yes as it was right next to the studio by the OXO building.

Another poor phone feed on an important topic to start todays show.

They probably don't have a budget for OBs so have to make do with what they can. If This Morning is going to tackle serious news stories regularly they should be able to utilise ITV News' resources.
