Abstract
A synchronizing signal generator device for television includes an oscillator circuit which generates a color subcarrier signal, a voltage-controlled oscillator circuit which includes a counter and whose oscillation frequency is controlled by the output signal of the first-mentioned oscillator circuit, a counter which receives an output of the voltage-controlled oscillator circuit, and a decoder which receives an output of the second-mentioned counter. The decoder provides a synchronizing signal for the NTSC, or SECAM format in such a manner that the count numbers of the respective counters are controlled. The synchronizing signal generator device for television also includes various circuits for receiving external synchronizing signals. As a result, the synchronizing signal generator device for television can be synchronized with another synchronizing signal generator device for television.
