Supporting video applications through 4DIS temporal framework 4DIS temporal framework

Video has become an essential component of multimedia applications nowadays. To support multimedia and video applications efficiently, video objects must be modeled and structured in secondary storage effectively, allowing flexible; easy, and efficient retrieval. Existing video database systems are quite ad hoc, each being designed for a specific kind of application. In this paper, we illustrate that a temporal database system is crucial in providing powerful capabilities for supporting both storage and manipulation requirements of a generic video manipulation framework. We present the design of our experimental prototype which is developed upon the 4DIS temporal database system. Utilizing the query capability of the 4DIS system, abstraction primitives are developed to provide a core set of operations for various kinds of application semantics. In particular, the temporal database system provides persistent storage for video objects and query capabilities for retrieving video objects. Functional capabilities of various video applications could then be easily developed upon this core set of operations.
