ABSTRACT:
A mask circuit masks a digital video signal so that a video signal of an analog video signal is not outputted for a predetermined period after the start of output of a horizontal synchronizing signal of the analog video signal. A period of masking the digital video signal by the mask circuit is set in a control register, and the control register transmits the masking period to the mask circuit. A digital video signal to analog video signal converting unit converts the digital video signal masked and outputted from the mask circuit into an analog video signal. Thus, by setting in the control register the period of masking the digital video signal until the video signal of the analog video signal is stabilized, a digital video encoder can output a stable video signal.
