That 'little white block' used to be used on US networks. The last time that
I remember it being used would probably be in the middle 1980's, but game
shows used to do it all of the time.
On the NBC HDTV network, they have a cute thing, where the network sends
a peacock being 'assembled' like a computer screen saver. 20 seconds before
the restart of the programming, a flag appears. However, it is very unlikely that
is the primary method for cueing the stations from the network. (I sure hope not!!!)
