ABSTRACT:
In a television system, the display by a monitor forms a high resolution window-like frame that is selectively movable about a larger scene which is transmitted as an array of contiguous frames. Separate tracks on a disc-type recorder are used to store a video signal from a camera corresponding to each frame making up the array of contiguous frames in the scene. Either the camera or the scene is repositioned to view each frame in the scene. The video signals are recorded at phase-displaced relations by phase shifting the sweep waveform supplied to the camera while scanning each component of the scene. The replayed video signals corresponding to the array of contiguous frames in the scene are blanked by gates controlled by adjustable delay circuits to select a single frame of unblanked video signal for display by a monitor which corresonds to a portion of the entire scene.
