Starting the Nipkow disk with 32 line NBTV video standard and vertical scanning. This is a video standard similar to that John Logie Baird used in the 1920's. Displaying the Indian Head test pattern. The black vertical bars in the starting process are part of the synchronisation signal. The moving vertical bars in the test pattern are due to different frame rate. The Nipkow disk operates with 12.5 frames per second, the camera with 25 frames per second.
