July, 1939] MOTION PICTURE FILM AND TELEVISION 13 The control equipment provides means for varying the video signal gain, the picture brightness, and the picture background illumination, and for starting and stopping the film projector. In an installation designed to provide a continuous program from motion picture film, where two or more film projectors and television channels are included, controls are also provided for switching from one channel to another. The monitor equipment includes a 12-inch Kinescope by means of which television images obtained from the film can be viewed. It includes also a cathode-ray oscilloscope for observing FIG. 9. Television control equipment for studio and film type the wave-shapes and amplitudes of the television signals. This monitor equipment is usually located so that it may be observed conveniently by the operator manipulating the control apparatus. The synchronizing generator supplies the several complex waveforms required to determine the timing of scanning processes in the transmitting equipment and to synchronize the reconstruction of the images at the receivers. The wave-shapes of the synchronizing signals have been standardized by the Radio Manufacturers Association. Views of television equipment of a type suitable for television broadcasting stations are shown in Figs. 9 and 10. Fig. 9 shows an installation of control equipment for studio and film type cameras.
