Abstract

A method and system in a data processing system for efficiently managing the selection and/or presentation of a multimedia data set comprised of multiple topics. A display is provided for presenting a multimedia data set. A graphic control mechanism having multiple portions is presented within the display. Each of the portions of the graphic control mechanism is associated with a selected one of the multiple topics, and such an association is graphically displayed. A user is then permitted to select one of the multiple portions of the graphic control mechanism. In response to a user selection of one of the multiple portions, an associated one of the multiple topics is automatically presented.

4. A method in a data processing system for efficiently managing the presentation of said multimedia data set according to claim 1 wherein said graphic control mechanism includes at least one user selectable graphic control button and wherein the step of permitting a user to select one of said plurality of portions of said graphic control mechanism further includes the step of selecting an alternate one of said plurality of topics in response to a user selection of said at least one user selectable graphic control button.

5. A method in a data processing system for efficiently managing the presentation of said multimedia data set according to claim 1 wherein said graphic control mechanism includes said textual indicia displayed at a selected resolution and wherein the step of permitting a user to select one of said plurality of portions of said graphic control mechanism further includes the step of changing said selected resolution in response to a user selection of one of said plurality of portions.

6. A method in a data processing system for efficiently managing the presentation of said multimedia data set according to claim 1 wherein said graphic control mechanism includes a first graphic control mechanism having a plurality of portions and having said textual indicia displayed at a first selected resolution and a second graphic control mechanism having a plurality of portions and having textual indicia displayed at a second selected resolution, and wherein said step of permitting a user to select one of said plurality of portions of said graphic control mechanism further includes the step of changing a range of portions displayed in said second graphic control mechanism in response to a user selection of one of said plurality of portions within said first graphic control mechanism.

7. A method in a data processing system for efficiently managing the presentation of said multimedia data set according to claim 6 wherein said first selected resolution of said first graphic control mechanism having a plurality of portions and having said textual indicia displayed is a lower resolution than said second selected resolution of said second graphic control mechanism having a plurality of portions and having said textual indicia displayed and wherein said step of changing a range of portions displayed in said second graphic control mechanism in response to a user selection of one of said plurality of portions within said first graphic control mechanism further includes the step of displaying a range of portions in said second graphic control mechanism centered about said selected one of said plurality of portions within said first graphic control mechanism.

8. A data processing system for efficiently managing the presentation within a display of a multimedia data set having a plurality of topics that each have a presentation time necessary for presenting said topic in said data processing system, said system comprising:

means for displaying a graphic control mechanism having a plurality of portions within said data processing system;

means for associating each of said plurality of topics with one of said plurality of portions of said graphic control mechanism, wherein each of said plurality of portions is proportionately sized to graphically indicate a presentation time for said associated topic;

means for displaying textual indicia in locations proximate to each associated one of said plurality of proportionately-sized portions of said graphic control mechanism for indicating said association between said plurality of topics and said plurality of portions of said graphic control mechanism, wherein said locations are spaced apart for indicating a relative temporal location of each of said plurality of topics within said multimedia data set;

means for permitting a user to select one of said plurality of portions of said graphic control mechanism; and

means for automatically presenting an associated one of said plurality of topics within said data processing system in response to a user selection of one of said plurality of portions of said graphic control mechanism, wherein presentation of said plurality of topics within said multimedia data set may be efficiently managed.

9. The data processing system for efficiently managing the presentation of said multimedia data set according to claim 8 wherein said means for displaying a graphic control mechanism having a plurality of portions comprises means for displaying a scroll bar having a plurality of portions.

10. The data processing system for efficiently managing the presentation of said multimedia data set according to claim 8 wherein said means for displaying a graphic control mechanism having a plurality of portions comprises means for displaying a slider control having a plurality of portions.

11.
