ABSTRACT:
A digital recording/reproducing apparatus having an external input digital interface is disclosed. A changeover switch is controlled by a changeover control circuit for selecting horizontal synchronizing signals generated by horizontal synchronizing generator for an external input mode and for selecting horizontal synchronizing signals derived from reproduced video signals reproduced from a recording medium for a playback mode. Standard color sub-carrier signals may be generated by a color sub-carrier signal generator based on the horizontal synchronizing signals as selected by the changeover switch. Even when the digital video signals supplied from outside for the external mode include non-standard horizontal synchronizing signals, standard composite video signals may be generated by an encoder by employing the color sub-carrier signals from the color sub-carrier signal generator.
