Abstract

Embodiments of the present invention provide data structures for modeling videoconference meetings, including videoconference meetings having only a single occurrence and videoconference meetings that repeat regularly, such as on a weekly or monthly basis. Some embodiments additionally model videoconference meetings that are part of a repeating series, but that have been canceled or moved to a different time, day, or the like, than the other videoconference meetings in the series. Embodiments of the present invention also provide methods for managing videoconference meetings, scheduling videoconference meetings, displaying the schedules, and monitoring videoconference participant load for videoconference meetings. Some embodiments additionally model videoconference media files, and methods for managing the media files.

Claims

1. A data structure, comprising:

a plurality of videoconference meeting entities each representing a videoconference meeting; and

a plurality of attributes for each of the videoconference meeting entities, the attributes comprising

one or more schedule attributes each having a value selected from the group consisting of

a scheduled start time of the respective videoconference meeting,

a scheduled end time of the respective videoconference meeting,

a scheduled duration of the respective videoconference meeting, and an interval type attribute having a value selected from the group consisting of

once only, indicating that the respective videoconference meeting comprises only one occurrence,

repeating, indicating that the respective videoconference meeting comprises a repeating series of occurrences, and

branched, indicating that the respective videoconference meeting comprises only one occurrence, and that the attributes of the respective videoconference meeting entity have the same values as the attributes of another one of the videoconference meeting entities having an interval type attribute value of repeating except for one or more of the schedule attributes.

2. The data structure of claim 1, wherein each of the videoconference meeting entities has a different meeting identifier, and wherein each occurrence of the videoconference meetings has a different index, further comprising:

a branch entity representing a relationship between a first one of the videoconference meeting entities having an interval type attribute value of repeating and a second one of the videoconference meeting entities having an interval type attribute value of branched; and

a plurality of attributes for the branch entity, the attributes comprising

a series identifier having a value representing a meeting identifier of the first one of the videoconference meeting entities,

a branch identifier having a value representing a meeting identifier of the second one of the videoconference meeting entities, and

an index of a videoconference meeting represented by the second one of the videoconference meeting entities.

3. A method for displaying a schedule of the videoconference meetings, which includes the data structure of claim 2, the method comprising:

selecting a coverage period for the schedule of meetings, the coverage period comprising a plurality of intervals; and

for each of the intervals in the coverage period, and each of the videoconference meeting entities having an interval type attribute value of repeating, displaying an indicator of the occurrence of the respective videoconference meeting when the occurrence of the respective videoconference meeting intersects temporally with the interval, and none of the series identifiers of the branch entities has a value representing the meeting identifier of the videoconference meeting entity representing the respective videoconference meeting.

4. The method of claim 3, further comprising:

determining whether the occurrence of the respective videoconference meeting intersects temporally with the interval, comprising at least one step selected from the group comprising

determining whether the scheduled start time of the respective videoconference meeting follows an end time of the interval, and

determining whether the scheduled end time of the respective videoconference meeting precedes a start time of the interval.

5. A medium or waveform containing a program of instructions adapted to perform the method of claim 3.

6. An apparatus to perform the method of claim 3.

7. The data structure of claim 2, further comprising:

a plurality of media entities each representing a link between a media file and one of the videoconference meeting entities.

8. A method for managing media entities, which includes the data structure of claim 2, the media entities each representing a link between a media file and one of the videoconference meeting entities, the method comprising:

storing one of the media files;

generating a first one of the media entities representing a link between the one of the media files and a selected one of the videoconference meeting entities; and

generating one or more second ones of the media entities each representing a link between the one of the media files and one of the branch entities having series identifier values representing the meeting identifier of the selected one of the videoconference meeting entities.

9. The method of claim 8, further comprising:

deleting the one of the media files when the first one of the media entities is deleted.

10. The method of claim 8, further comprising:

retaining the one of the media files when any of the second ones of the media entities are deleted.

11. A medium or waveform containing a program of instructions adapted to perform the method of claim 8.

12. An apparatus to perform the method of claim 8.

13. The data structure of claim 1, further comprising:

a plurality of invited videoconference participant entities each representing a videoconference participant invited to one of the videoconference meetings.

14. A method for calculating a videoconference participant load for an interval in a videoconference schedule, which includes the data structure of claim 13, the method comprising:

generating an array comprising, for each of the videoconference meetings having an occurrence that temporally intersects the interval,

generating a first data pair comprising a first participant value representing the number of the participant entities associated with the videoconference meeting and a first difference between a reference time and the start time of the videoconference meeting, and

generating a second data pair comprising a second participant value representing the negative of the number of the participant entities associated with the videoconference meeting and a second difference between the reference time and the end time of the videoconference meeting; and

traversing the array in order according to the first and second differences, comprising adding the first and second participant values to a participant total.

15. The method of claim 14, further comprising:

indicating a videoconference load violation when the videoconference participant total exceeds a predetermined maximum participant total.

16. A method for calculating a videoconference participant load for an interval in a videoconference schedule comprising a plurality of the videoconference meetings, the method comprising:

generating an array comprising, for each of the videoconference meetings having an occurrence that temporally intersects the interval,

generating a first data pair comprising a first participant value representing the number of videoconference participants associated with the videoconference meeting and a first difference between a reference time and the start time of the videoconference meeting, and

generating a second data pair comprising a second participant value representing the negative of the number of the videoconference participants

associated with the videoconference meeting and a second difference between the reference time and the end time of the videoconference meeting; and

traversing the array in order according to the first and second differences, comprising adding the first and second participant values to a participant total.

17. The method of claim 16, further comprising:

indicating a videoconference load violation when the videoconference participant total exceeds a predetermined maximum participant total.

18. A medium or waveform containing a program of instructions adapted to perform the method of claim 16.

19. An apparatus to perform the method of claim 16.
