I don't know what they did on the camera and transmission side, but having the sub-orbital view on the 1st stage all the way down to the barge was super impressive.
I'm curious to find out what they changed. One of the problems they previously had was that the vibration from the rocket landing was too much for a satellite connection on the barge (or it's nearby support ship); there were other issues on the rocket. Maybe being right next to the coast the whole time helps on a polar launch?
We'll see how it'll be for the Echostar 23 launch (and landing).
There was a live view from the barge on the technical stream through descent.
John Insprucker is far more of what you'd expect of a typical engineer. Reddit r/SpaceX went wild for a few minutes when they saw he was back doing the live broadcasts. People like his authenticity.
