Abstract
A synchronizing signal transmission system comprises: a circuit for mixing a horizontal synchronizing signal and a vertical synchronizing signal from a synchronizing signal generator and producing a mixed synchronizing signal having a first voltage-level range wherein horizontal synchronizing pulses exist only in a period corresponding to the pulse width of the vertical synchronizing signal, a second voltage-level range wherein the horizontal synchronizing pulses exist in all periods, and a third voltage-level range wherein the horizontal synchronizing pulses do not exist in a period corresponding to the pulse width of the vertical synchronizing signal and exist in other periods; a transmission line for transmitting the mixed synchronizing signal; and a circuit for separating the mixed synchronizing signal thus transmitted in accordance with the first, seconds, and third voltage-level ranges, leading out a signal corresponding to the second voltage-level range thus separated as a horizontal synchronizing signal, and, at the same time, processing signals corresponding respectively to the first through third voltage-level ranges thereby to obtain and lead out a vertical synchronizing signal.
