Abstract

1431052 Television-telephone system RCA CORPORATION 18 April 1973 [24 April 1972] 19023/72 Heading H4F A television-telephone system of the type including a storage tube which is connected between a television camera and a telephone line when transmitting a television video signal representative of moving object images to a remote receiver, a 60 Hz vertical deflection signal being supplied for example to the camera, wherein for transmitting a video signal representative of stationary object images the storage tube is decoupled from between the camera and telephone line and a 7¢ or 15 Hz vertical deflection signal is supplied for example to the camera. The stored moving image video signal may be read out from the storage tube for transmission using a 7¢ or 15 Hz vertical deflection signal. The necessary 60 and 7¢ (or 15) Hz sawtooth voltage waveforms are provided by a resistance-capacitance time constant network (Fig. 2, not shown) control pulses for which are developed from a sync. generator by a logic circuit arrangement (Fig. 1, not shown). The transmitted video signals may be monitored.
