ABSTRACT:
Editing apparatus is provided for controlling the transfer of signals from a playback medium to a recording medium. The apparatus includes a console having a plurality of display registers, including a play IN register for displaying play IN position data representing an edit-in point along the playback medium, a record IN register for displaying record IN position data representing an edit-in point along the recording medium, a play OUT register for displaying play OUT position data representing an edit-out point along the playback medium and a record OUT register for displaying record OUT position data representing an edit-out point along the recording medium. The console also has a plurality of register selector switches, each associated with and adjacent a respective one of the display registers and operable to select the display register associated therewith. A manually operable enabling switch enables position data to be displayed in a selected one of the play IN, record IN, play OUT and record OUT registers as a function of the position data displayed in the remainder of these registers. The apparatus also includes a central processing unit responsive to the operation of the enabling switch and a selected one of the register selector switches to obtain data representing the duration between the edit-in and edit-out points as represented by the position data displayed in two of the registers, neither of which is associated with the selected register switch, to combine the duration data with the position data displayed in a third register, which third register is not associated with the selected register switch, to produce resultant position data, and to cause this resultant position data to be displayed in the register which is associated with the register selector switch.
