ABSTRACT:
The proposed method of broadcasting television signals is such that the phase of the carrier signal as modulated with the video signal is shifted through 180.degree. from one line to the next within a field. Measure ensures that the disturbance signal due to a transmitter operating in the same channel will produce opposite effects from one line to the next, i.e. a brightening in one line and a darkening in the next. These opposite disturbances of adjacent lines are then compensated by the vision of the viewer or by electronic circuits specially designed for this purpose, so that the picture data originating from the interfering transmitter will not be perceived by the viewer.
