Abstract

A method and apparatus are provided for playback conflict detection. In one embodiment, the invention determines a time interval for the playback of the isosynchronous data object, said time interval including both a beginning time and a duration, and determines whether any calendar event falls at least partially within the time interval for playback. The invention may be initiated by opening the isosynchronous data object for playback. The user who requested the playback will be notified of any potential conflict between the complete playback of the data object and any events scheduled on the user'"'"'s electronic calendar.

Claims

1. A method, performed in a data processing system that includes an electronic calendar having an owner, for detecting a conflict between playback of an isosynchronous data object and a conflicting calendar event of the electronic calendar, the method comprising the computer implemented steps of:

determining a time interval for playback of the isosynchronous data object, said time interval including both a beginning time and a duration;

determining whether a conflicting calendar event falls at least partially within the time interval for playback; and

notifying the owner of the electronic calendar containing the conflicting calendar event that a conflicting calendar event falls at least partially within the time interval for playback.

2. The method of claim 1, wherein the step of determining whether a conflicting calendar event falls at least partially within the time interval for playback is initiated in response to a request to playback the isosynchronous data object and the beginning time is the time of the request.

3. The method of claim 1, wherein the step of determining whether a conflicting calendar event falls at least partially within the time interval for playback is initiated in response to a user-initiated request, received from the owner of the electronic calendar containing the conflicting calendar event, to playback the isosynchronous data object.

4. The method of claim 3, wherein the method further comprises the computer implemented step of accessing an electronic calendar of the user initiating the request to playback.

5. The method of claim 1, further comprising the computer implemented step of determining the duration by preplaying the isosynchronous data object.

6. The method of claim 1, further comprising the computer implemented step of determining the duration by applying a display rate to the isosynchronous data object.

7. A data processing system for detecting a conflict between playback of an isosynchronous data object and a conflicting calendar event of an electronic calendar, comprising:

an electronic calendar having an owner;

means for determining a time interval for playback of the isosynchronous data object, said time interval including both a beginning time and a duration;

means for determining whether a conflicting calendar event of the electronic calendar falls at least partially within the time interval for playback; and

means for notifying the owner of the electronic calendar containing the conflicting calendar event that a conflicting calendar event falls at least partially within the time interval for playback.

8. The data processing system of claim 7, wherein the means for determining whether a conflicting calendar event of the electronic calendar falls at least partially within the time interval for playback is responsive to a request to playback the isosynchronous data object and the beginning time is the time of the request.

9. The data processing system of claim 7, wherein the means for determining whether a conflicting calendar event of the electronic calendar falls at least partially within the time interval for playback is responsive to a user-initiated request, received from the owner of the electronic calendar containing the conflicting calendar event, to playback the isosynchronous data object.

10. The data processing system of claim 9, wherein the data processing system further comprises means for accessing an electronic calendar of the user initiating the request to playback.

11. The data processing system of claim 7, further comprising means for determining the duration by preplaying the isosynchronous data object.

12. The data processing system of claim 7, further comprising means for determining the duration by applying a display rate to the isosynchronous data object.

13. A computer program product, for use in a data processing system, for detecting a conflict between playback of an isosynchronous data object and a conflicting calendar event of an electronic calendar, said data processing system including an electronic calendar having an owner, the computer program product comprising:

a computer usable storage medium having computer readable program code embodied in said storage medium for granting access to the data processing system, said computer program product including;

computer readable program code means for determining a time interval for playback of the isosynchronous data object, said time interval including both a beginning time and a duration;

computer readable program code means for determining whether a conflicting calendar event of the electronic calendar falls at least partially within the time interval for playback; and

computer readable program code means for notifying the owner of the electronic calendar containing the conflicting calendar event that a conflicting calendar event falls at least partially within the time interval for playback.

14. The computer program product of claim 13, wherein the computer readable program code means for determining whether a conflicting calendar event of the electronic calendar falls at least partially within the time interval for playback is responsive to a request to playback the isosynchronous data object and the beginning time is the time of the request.

15. The computer program product of claim 13, wherein the computer readable program code means for determining whether a conflicting calendar event of the electronic calendar falls at least partially within the time interval for playback is responsive to a user-initiated request, received from the owner of the electronic calendar containing the conflicting calendar event, to playback the isosynchronous data object.

16. The computer program product of claim 15, wherein the data processing system further comprises means for accessing an electronic calendar of the user initiating the request to playback.

17. The computer program product of claim 13, further comprising computer readable program code means for determining the duration by preplaying the isosynchronous data object.

18. The computer program product of claim 13, further comprising computer readable program code means for determining the duration by applying a display rate to the isosynchronous data object.
