People have been commenting on the test pattern at the White House/UFC and FIFA locations.
Yes, they are for calibrating frequency....although I found something interesting in learning more about it -
'These are generated by test signal generators, which do not depend on the correct configuration (and presence) of a camera, and can also test for additional parameters such as correct color decoding, sync, frames per second, and frequency response. These patterns are specially tailored to be used in conjunction with devices such as a vectorscope, allowing precise adjustments of image equipment.
The audio broadcast while test cards are shown is typically a sine wave tone..'
But it was rather odd (and yet another synch), that when I looked this up, on the same page it promptly led me to a Netflix example calibration test show, used for the same purposes.
Very David Lynch-like style, and at the end of the short calibration video the actor quotes the grim and foreboding opening monologue on Rome, from Shakespeare's Julius Caesar.
And just before that he runs his hand under a flowing grail-like fountain, performs the famed backward moonwalk, and tosses around a soccer ball.
We just had the flyby of the backside of the moon, we are now in the opening stages of the FIFA World Cup Soccer, as well as the fountain additionally looking very like the DuPont Circle Fountain, one of the DC grid nodes. (I threw the recent Sagrada Família in there too, because of a resemblance to test patterns and interesting light & color depictions.)
Get ready for some upcoming 'special programming'.
In addition to Trump's birthday, the fight spectacle also falls on the ancient Roman festival of Quinquatrus Minores, with gladiator games and music.
This West World is Rome. Rome never ended.
Social media is the Circus.
Public figures are the gladiators/entertainment for us, the mob.
The mob is simultaneously caught, sedated, & fueled by the net.
