Is there a name for this video artifact effect in this image? I’d love to see a bunch of this.

It reminds me of the early 2000’s digital satellite television. Any time the signal got blocked a bit by the weather, the on-screen content would do this. Very trippy. Later on when cable tv in my area switched to digital, I noticed it happening there, too, but nowhere near as often as in satellite. Now that over the air is all digital where I live, however, I almost never see this happening anymore. I guess it’s not a thing that happens as much with modern encoding formats.
