Method and apparatus for generating three coordinate signals x, y, z for an x, y, z display device

摘要

A composite signal is transmitted via a transmission line to an x, y, z display device. The composite signal contains in each of a plurality of predetermined time intervals an identifiable signal. The first signal of said composite signal is a synchronizing start signal. The other signals contain varying information. In the display device there are generated an x-, a y- and a z-coordinate signal. These coordinate signals are generated such that in said predetermined time intervals with reference to the synchronizing start signal and in predetermined varying combinations two of these three coordinate signals are developed and determined by the display device, whereas the remaining third coordinate signal is developed by the display device, but is determined from one of the other signals of the composite signal received via the transmission line.
