APPARATUS FOR SELECTIVELY TRANSFERRING DATA BETWEEN REGISTERS ABSTRACT OF THE DISCLOSURE Apparatus is provided for selectively transferring data from one to another of a plurality of display registers. Selector switches are associated with respective ones of the display registers, each selector switch being manually operable so as to be designated either as a source switch or as a destination switch, whereby the data in the display register associated with the source switch is transferred to the display register associated with the destination switch. A central processing unit is responsive to the operation of a first of the selector switches followed by the operation of a second of the selector switches to transfer the data from the display register associated with the first selector switch to the display register associated with the second selector switch. Preferably, indicators are associated with respective ones of the selector switches; and the central processing unit controls the indicator associated with the first-operated selector switch to provide a distinctive indication represent- ing that this selector switch has been designated as the source switch. A desired application of this invention is in video editing apparatus that is used with video playback and record- ing devices in which video information that is reproduced from one device is recorded on the other. In such an application, the data in the respective display registers is position data representing relative positions of the record media of the playback and recording devices. Such display registers constitute a present position register for displaying the present position of one of the record media, a "start" register for displaying the position at which the start of an edit operation is to commence, and a "stop" register for displaying the position at which the edit operation is to end.
