Answer:

This a test pattern transmitted by the RCA during black and white TV era. There test patterns were used by people to calibrate their TV displays. This is the B&W version of the color bar test pattern which most of us have seen on Doordarshan :)

As time passed, calibration of TVs became more and more irrelevant and they were phased out.
