Abstract: PURPOSE:To allow each exchange to receive a control signal by supplying a control signal to a transmission line connecting exchanges without modulating the control signal independently of channel tuning of a tuner. CONSTITUTION:A video signal SV and an audio signal SA are modulated by a frequencies different from exchanges E1-EN respectively, supplied to a transmission line 100 connecting the exchanges E1-EN and a control signal SC is supplied to the transmission line 100 as it is. Since the control signal SC is supplied as it is to the line 100 without modulation, the exchanges E1-EN receive the control signal SC immediately independently of the channel tuning of the tuner.

Abstract: PURPOSE:To project a picture satisfactorily with simple constitution by forming a picture projecter with use of a beam index-type color image receiving tube. CONSTITUTION:Video light beams from beam index-type color image receiving tubes 1L and 1R are projected on a screen 4 through lens systems 2L and 2R and deflection boards 3L and 3R different in deflection angles at 90 deg.. An observer views the screen 4 through eyeglasses where deflection boards 5L and 5R matching to the deflection angles of pictures are provided on left and right eyes. Consequently, pictures from two image receiving tubes 1L and 1R are independently supplied to right and left eyes of the observer, and the stereoscopic observation is executed. By utilizing a beam index-type color image receiving tubes as the image receiving tubes 1L and 1R, an extremely bright picture can be obtained through the deflection boards 3L and 3R. When a display is executed with the aid of a single video signal, the same video light beam is projected from two image receiving tubes 1L and 1R, whereby the picture can be brightened twise. In this case, the deflection boards 3L and 3R are unnecessary.

Abstract: PURPOSE:To detect precisely a leading end of an effective screen with simple constitution by detecting the time when an electron beam passes through a stripe electrode. CONSTITUTION:A stripe electrode Sb connected to an index electrode Ib is provided closer to the horizontal scan start side than a stripe electrode Sa. Thus, when an electron beam is much closer to the horizontal scan start side than the electrode Sb, said electron beam is absorbed by the electrode Sb. When the electron beam passes through the electrode Sb and draws near to the electrode Sa, a detection signal is obtained from the electrode Sa. As a result, the point when an electron beam passes through the electrode Sa can be made precise in the receiver, and a white signal (WHT) and switch signals (SA and SB) can be generated properly from the detection signal.
