Synchronized retrieval of recorded multimedia data

This paper describes techniques for the retrieval of recorded multimedia data for supervisory control systems. Currently these systems operators can only retrieve recorded data individually. We developed new techniques to access all recorded data is synchronization. The techniques enable users to retrieve multimedia data such as sensor data and videos simultaneously, and also enable users to obtain the desired related data, including objects in videos, by "Drag and Drop" operation. All these techniques allow operators to exactly and quickly analyze phenomena in the systems based on the recorded multimedia data.
