ABSTRACT OF THE DISCLOSURE A signal processing device in which a video signal and a digital signal are subjected to digital processing simultaneously in such a manner that the number of A/D or D/A converters is reduced. An analog input video signal is A/D converted to produce a cyclical signal synchronized with a horizontal or vertical synchronizing signal contained within the video signal. The signal so converted is then processed via an arithmetic unit, and then other digital information is added thereto. The finally processed signal is transmitted via an internal bus in synchronization with the horizontal or vertical synchronizing signal component of the video signal
