Video objects are temporal in nature~ A video object is com- posed of a set of video frames which are related in a total time ordering. By imposing additional timing constraints among video frames, various presentation operators on video objects could be defined. A core set of presentation operators include Play, Pause, Resume, Fast Forward, Fast Backward, Slow Mo- tion, and Stop. A video database system must be able to support the temporal ordering of video frames and the tem- poral constraints required by any presentation operators. In this paper, we demonstrate how our Four Dimen- sional Information Space (4DIS) temporal database system is used to model video objects and the presentation opera- tors. Since rime'is defined as a first class object in 4DIS, querying operators and constraints for time objects are sup- ported, These temporal querying operators and constraints are used to describe the timing requirements of video objects and the presentation operators. This allows users to describe video objects and operators declaratively, without worrying about their low level representation. Furthermore, a user could specify arbitrary operations on video objects using the query language supported by 4D1S. This is in contrast with existing video database systems in which operators on video objects are limited and are defined in advance. |
