Abstract

An edit controller for controlling editing of recorded audio and/or video material, in which temporally successive material clips of a edited output material sequence are represented by corresponding clip icons on a display screen, comprises cursor controller for providing user control of a cursor on the display screen; selection controller for selecting an operation to be performed by the edit controller in dependence on the current position of the cursor on the display screen when the selection controller is activated by the user; logic for defining first and second display screen selection areas for each clip icon, the first and second display screen selection areas each having a predefined position on the display screen with respect to a current display position of the respective clip icon; logic, responsive to user operation of the selection controller while the cursor is displayed within the first selection area associated with a clip icon for initiating replay of the output material sequence from the start of the material clip corresponding to that clip icon; and logic, responsive to user operation of the selection controller while the cursor is displayed within the second selection area associated with a clip icon for initiating replay of the output material sequence from a point within the material clip corresponding to that clip icon which is a predetermined time before the end of that material clip.

Claims

1. An edit controller for controlling editing of recorded audio and/or video material, in which temporally successive material clips of an edited output material sequence are represented by corresponding clip icons on a display screen, said controller comprising:

cursor control means for providing user control of a cursor on said display screen;

selection control means for selecting an operation to be performed by said edit controller in dependence on the current position of said cursor on said display screen when said selection control means is activated by the user;

logic for defining first and second display screen selection areas for each clip icon, said first display screen selection area having a predefined position on said display screen with respect to a current display position of the respective clip icon and said second display screen selection area having a predefined position with respect to a current display position of said respective clip icon and/or a next clip icon in the temporal replay order;

logic for responding to user operation of said selection control means when said cursor is displayed within said first selection area associated with a clip icon for initiating replay of said output material sequence from the start of the material clip corresponding to that clip icon; and

logic for responding to user operation of said selection control means when said cursor is displayed within said second selection area associated with a clip icon for initiating replay of said output material sequence from a point within said material clip immediately before said second selection area which is a predetermined time before the end of that material clip.

2. An edit controller according to claim 1, in which said clip icons are displayed in temporal order along a predetermined screen direction.

3. An edit controller according to claim 2, in which said predetermined screen direction is a horizontal screen direction.

4. An edit controller according to claim 1, in which said first selection area overlies the centre of the corresponding clip icon.

5. An edit controller according to claim 1, in which said second selection area is at least partially disposed between the corresponding clip icon and the temporally following clip icon.

6. An edit controller according to claim 5, in which said second selection area overlies an edge region of said corresponding clip icon and/or an edge region of said temporally following clip icon.

7. An edit controller according to claim 1, comprising means for displaying a respective different cursor when said cursor is positioned within said first and said second screen selection areas.

8. An edit controller according to claim 1, in which:

said cursor control means comprises a mouse, trackerball or joystick; and

said selection control means comprises a mouse button, a trackerball button or a joystick button respectively.

9. A method of operation of an edit controller, in which temporally successive audio and/or video material clips of a edited output material sequence are represented by corresponding clip icons on a display screen, said controller comprising a cursor controller for providing user control of a cursor on said display screen;

and a selection controller for selecting an operation to be performed by said edit controller in dependence on the current position of said cursor on said display screen when said selection controller is activated by the user;

said method comprising;

defining first and second display screen selection areas for each clip icon, said first display screen selection area having a predefined position on said display screen with respect to a current display position of the respective clip icon and said second display screen selection area having a predefined position with respect to a current display position of said respective clip icon and/or the next clip icon in the temporal replay order;

initiating replay of the output material sequence, in response to user operation of said selection controller when said cursor is displayed within said first selection area associated with a clip icon, from the start of the material clip corresponding to that clip icon; and

initiating replay of the output material sequence, in response to user operation of said selection controller when said cursor is displayed within said second selection area associated with a clip icon, from a point within the material clip immediately before said second selection area which is a predetermined time before the end of that material clip.
