摘要： A video synchronous detector apparatus for discriminating a video intermediate frequency signal, in which the video intermediate frequency signal is divided into two parts, one of which is applied to one terminal of a multiplier circuit, and the other of which is applied to the other terminal of the multiplier circuit through a picture-carrier intermediate frequency extraction circuit having a frequency selection circuit and a limiter circuit. The frequency selection circuit is provided with a trap circuit. The trap circuit has a center resonance frequency equal to a differential frequency between a picture-carrier intermediate frequency (f.sub.p) and a differential frequency between a color subcarrier intermediate frequency (f.sub.c) and a sound-carrier intermediate frequency (f.sub.s) so that a so-called sound-cross-color disturbance caused by a beat between the intermediate frequency sound signal and the intermediate frequency picture signal may be reduced.

摘要： There is provided a receiving system for receiving the video signal for each one frame. The video signal is divided into line signals each corresponding to the horizontal scanning period and transmitted sequentially in such a manner that each line signal is inserted in a television signal during each vertical blanking period.The line signals inserted in the transmitted television signal are separated therefrom and the separated line signals are selectively recorded on the odd and even field tracks of a rotary recording medium.Switches for selectively recording the line signals on the even field and odd field tracks are controlled by the output of an odd/even field selection signal generating circuit. The number of revolutions of the rotating recording medium is determined so that the line signals selectively recorded on the even field and odd field tracks of the rotating recording medium are arranged in the correct order and without leaving any spaces between the line signals or causing the line signals to overlap with each other. When the video signals for one frame have been recorded on the rotating recording medium, the one-frame video signals recorded on the rotating recording medium are repeatedly read out to reproduce a still picture.

摘要： A multiplex signal transmission system in which a plurality of information signals, having respectively arbitrary time durations and being arranged in time-serial form, are sequentially divided into a plurality of signal portions by a predetermined time period, said signal portions being successively allocated in time-parallel form to a plurality of transmission channels, each of which has a time duration of said predetermined time period, and being transmitted repeatedly through respectively allocated channels every said time duration, comprises a channel shift means for shifting sequentially the channel allocation of said signal portions at predetermined time periods, and a signal transmitting means for transmitting in time-parallel form said signal portions derived from said channel shift means repeatedly through every preceding channels. Consequently, the transmission line can be efficiently utilized in such a way that, at the sending end, a plurality of information signals having respectively arbitrary time durations are folded into a plurality of transmission channels having given time periods, and besides that, at the receiving end, once a portion of any desired information signal is caught in a corresponding channel, successive signal portions can be derived sequentially from the same channel every said given time periods. Hence, a channel selecting means of a receiver in this system can be simplified.
