Display systems according to the television grating method, noting graphical representation

The generation of graphical representations based on vectors and using a grating method was investigated for television receivers. The basic background for the selection of the television grating deflection is the fact that two information systems can be combined: analog and digital. By keeping to television standards, video images and digitally produced graphical or alphanumeric information can be combined on the screen. Colored displays present no problem if one replaces the black-and-white receiver by a color television set.
