Abstract

A method of conceptually magnifying video browser data, the data being organised hierarchically in one or more levels (304, 312) is disclosed. The method comprises firstly selecting a parent level (304), the parent level selection making visible a first key frame (340) associated with the parent level (304). A magnification mode is also selected, being either a parent-only, or a parent-children magnification mode. Conceptual magnification is then performed, which displays, in the parent-only mode, the first key frame (340) associated with the parent level (304), and other frames (300, 302) which are also associated with the parent level. The conceptual magnification displays, in the parent-children mode, the first key frame (340) associated with the parent level (304), and second key frames (324) associated with an associated child level (312).

Claims

1. A method of presenting, in a display, video browser data, said data being organized hierarchically in one or more levels, each of such levels including multiple frames including a key frame, the method comprising the steps of:

selecting a parent level, said parent level selection displaying, in a first display area, a key frame associated with said parent level;

choosing one of a parent-only and a parent-children magnification mode;

if the parent-only mode is chosen, displaying in a second display area, in magnified form relative to the key frame displayed in the first display area, the key frame associated with said parent level and other key frames which are also associated with said parent level; and

if the parent-children mode is chosen, displaying in said second display area, in magnified form relative to the key frame displayed in the first display area, the key frame associated with the parent level and key frames associated with child levels associated with the parent level.

2. The method of claim 1,

wherein in relation to the parent only-mode, said step of displaying further comprises indicating presence of undisplayed data associated with the key frame and the other key frames associated with the parent level,

and wherein in relation to the parent-children mode, said step of displaying further comprises indicating presence of undisplayed data associated with the key frame associated with the parent level and the key frames associated with the child levels.

3. The method of claim 1, wherein in the parent-only mode, said displaying step comprises sub-steps of:

automatically displaying the key frame associated with said parent level for a first time interval; and

automatically displaying the other key frames which are also associated with said parent level for a second time interval,

and wherein in the parent-children mode, said displaying step comprises sub-steps of;

automatically displaying the key frame associated with said parent level for a third time interval; and

automatically displaying said key frames associated with said associated child levels for a fourth time interval.

4. The method of claim 1, wherein said key frames comprise one or more of text and image data.

5. An apparatus for presenting, in a display, video browser data, said data being organized hierarchically in one or more levels, each of such levels including multiple frames including a key frame, the apparatus comprising:

parent level selection means for selecting a parent level, said parent level selection displaying, in a first display area, a key frame associated with said parent level;

magnification mode selection means for choosing one of a parent-only and a parent-children magnification mode;

means for displaying in a second display area, if the parent-only mode is chosen, in magnified form relative to the key frame displayed in the first area, said key frame associated with said parent level and other key frames which are also associated with said parent level; and

means for displaying in said second display area, if the parent-children mode is chosen, in magnified form relative to the key frame displayed in the first area, said key frame associated with said parent level and key frames associated with child levels associated with the parent level.

6. The apparatus of claim 5,

wherein, in relation to the parent-only mode, said means for displaying is adapted for indicating presence of undisplayed data associated with the key frame and the other key frames associated with the parent level;

and wherein in relation to the parent-children mode, said means for displaying is adapted for indicating presence of undisplayed data associated with the key frame associated with the parent level and the key frames associated with the child levels.

7. The apparatus of claim 5, wherein representations of the hierarchically organized video data levels are spatially disposed in relation to selection means, which selection means comprises a radially adjustable pointer whose radial orientation relative to the representations is indicative of the hierarchical level to be selected.

8. The apparatus of claim 7, further comprising an adjustable scrolling means which is adapted, in response to an adjustment of said adjustable scrolling means, to linearly translate the representations of the hierarchically organized video data levels in relation to the selection means, thereby effecting a change in the radial orientation of the selection means relative to the representations, said changed radial orientation relative to the representations being indicative of the hierarchical level to be selected.

9. A computer-readable medium having a computer-executable program stored thereon, the program for directing an apparatus for presenting, in a display, video browser data, said data being organized hierarchically in one or more levels, each of such levels including multiple frames including a key frame, the program comprising:

code for selecting a parent level and for displaying, in a first display area, a key frame associated with said parent level;

code for choosing one of a parent-only and a parent-children magnification mode;

code for displaying in a second display area, if the parent-only mode is chosen, in magnified form relative to the key frame displayed in the first area, said key frame associated with said parent level and other key frames which are also associated with said parent level; and

code for displaying in said second display area, if the parent-children mode is chosen, in magnified form relative to the key frame displayed in the first area, said key frame associated with said parent level and key frames associated with child levels associated with the parent level.

10. The computer-readable medium of claim 9,

wherein in relation to the parent-only mode, said code for displaying comprises code for indicating presence of undisplayed data associated with the key frame and the other key frames associated with the parent level,

and wherein in relation to the parent-children mode, said code for displaying comprises code for indicating presence of undisplayed data associated with the key frame associated with the parent level and the key frames associated with the child levels.

11. The computer-readable medium of claim 9, wherein in relation to the parent-only mode, said code for displaying comprises code for:

automatically displaying the key frame associated with said parent level for a first time interval; and

automatically displaying the other key frames which are also associated with said parent level for a second time interval,

and wherein in relation to the parent-children mode, said code for displaying comprises code for;

automatically displaying the first key frame associated with said parent level for a third time interval; and

automatically displaying said key frames associated with said associated child levels for a fourth time interval.

12. The computer-readable medium of claim 9, wherein said key frames comprise one or more of text and image data.
