US 4,283,745 A · Editing apparatus

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.

Editing apparatus for controlling the transfer of signals from a playback medium to a recording medium, said apparatus comprising a console including a plurality of display registers, including a play IN register for displaying play IN position data representing an edit-in point along said playback medium, a record IN register for displaying record IN position data representing an edit-in point along said recording medium, a play OUT register for displaying play OUT position data representing an edit-out point along said playback medium and a record OUT register for displaying record OUT position data representing an edit-out point along said recording medium, a plurality of register selector switches, each associated with and adjacent a respective one of said display registers and operable to select the display register associated therewith, and enable means manually operable to enable position data to be displayed in a selected one of said play In, record IN, play OUT and record OUT registers as a function of the position data displayed in the remainder of said registers;

and central processing means responsive to the operation of said enable means and a selected one of said 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 said registers, neither of which is associated with said selected register switch, to combine the duration data with the position data displayed in a third register, which third register is not associated with said selected register switch, to produce resultant position data, and to cause said resultant position data to be displayed in the register associated with said register selector switch.

Editing apparatus for controlling the transfer of video signals from a playback medium to a recording medium, said apparatus comprising a console having a plurality of display registers, including a play IN register associated with the playback medium for displaying play IN position data representing an edit-in point along said playback medium, a record IN register associated with the recording medium for displaying record IN position data representing an edit-in point along said recording medium, an play OUT register associated with the playback medium for displaying play OUT position data representing an edit-out point along said playback medium, a record OUT register associated with the recording medium for displaying record OUT position data representing an edit-out point along said recording medium, and at least one additional register selectively associated with the playback recording medium for displaying position data selectively representing an intermediate edit-in or edit-out point along said playback or recording medium, a plurality of register selector switches, each associated with and adjacent a respective one of said display registers and operable to select it associated register;

and central processing means operable in a selected mode and including means for sensing the particular register selected by the operation of a register selector switch;
means for establishing a P1 character equal to:
(a) the position data representing the edit-in point along the same medium as that with which said selected register is associated if said selected register is the play OUT or record OUT register, (b) the position data representing the edit-out point along the same medium as that with which said selected register is associated if said selected register is the play IN or record IN register, and (c) the position data representing the edit-in point along the medium which is other than that with which said selected register is associated if said selected register is the additional register;
means for establishing a P2 character equal to:
(a) the difference between the edit-out and edit-in points for the medium which is other than that with which said selected register is associated if said selected register is the play IN, record IN, play OUT or record OUT register, and (b) the difference between the intermediate edit and the edit-in points for the same medium as that with which said selected register is associated if said selected register is the additional register;
means for producing resultant position data equal to P1+P2 is neither said play IN nor said record IN register is selected;
means for producing resultant position data equal to P1-P2 is either said play IN or said record IN register is selected;
and means for displaying said resultant position data in said selected register.
