Abstract: A method and apparatus are disclosed for increasing vertical resolution of television and eliminating vertical aliasing by modulating vertical deflection of the camera a significant number of cycles per line, and modulating the vertical deflection of the display unit in phase with the modulation of the camera while displaying the video signal transmitted. The display unit is provided with its own modulating oscillator operating at the same stable frequency as the modulating frequency of the camera, and phase synchronized by information transmitted by the camera. In the case of NTSC color television, the vertical deflection modulating oscillator of the camera is the color modulating oscillator, and the vertical deflection modulating oscillator of the receiver is the oscillator used for color demodulation phase synchronized by color bursts gated during blanking periods of each frame.
