An encoder generating an analogue color signal is configured by a digital circuit. An external frame signal supplied from an external apparatus is counted by a clock pulse signal generated by a crystal oscillator, and a synchronizing signal to be added to the luminance signal is produced on the basis of a counted results, and all horizontal synchronizing periods of digital active lines are made identical, and in vertical blanking period, a predetermined horizontal synchronizing period is made variable.
