Research on Locating Video Format and Its Retrieving Method

This paper proposes a new video file format, which can integrate video information, audio information, as well as the spatial positioning information into a whole file. Based on this video format, the TMS320DM642 video processing platform is adopted to carry out embedded program. Then the method and workflow which employs RF5 (Reference Framework level 5) structure in real-time collecting locating video files are introduced. Given that the video frames have their corresponding spatial positioning information, we put forward a location-based information retrieval algorithm and the rapid and efficient retrieval of the video clips in the chosen region from an electronic map can be realized.
