The electrical transmission and reception of transient visual images. Like motion pictures, television consists of a series of successive images which are registered in the brain as a continuous picture because of the persistence of vision. Each visual image impressed on the eye persists for a fraction of a second. At the television transmitter, minute portions of a scene are sampled individually for brightness and color, and the information for each portion is transmitted consecutively. At the receiver, each portion is synchronized and reproduced in its proper position and with correct brightness and color to reproduce the original scene.
