Video Database Management System

Advances in multimedia computing technologies have offered new opportunities to store, manage, and present video data in databases. Object oriented technology on the other hand provides novel ways to organise the multimedia items, by supporting both the temporal as well as spatial properties. Many researchers come up with data models by implementing object oriented concepts into multimedia technology. The aim of this work is to make a video data model, called VDbMS (Video Data Base Management System) by incorporating and integrating the above mentioned technologies. This report summarises the current progress of this research in the development of VDbMS. The intention of this database system is to provide an effective way for storing video data, optimal query parsing and an ideal interface for user interactivity. This report is separated into six sections. Section 2 briefly reviews the previous twelve months. Section 3 depicts the work carried out in the next six months in developing the video model. Section 4 tells us about the experiments on the video data. Section 5 is about the conclusions and the line of action for future work and finally section 6 is the appendixes for some video models and MPEG4 A lot of work is going on in the field of video data modelling and its applications, due to its high commercial value. Since video itself is a very complex object with both spatial and temporal properties, researchers are still unable to get a proper and comprehensive data model. A summary of literature review covering various video data models (annotation The functionality of a database is measured by data manipulation and query processing. A query for video data is very complex in nature. It is also possible that a database user can make a content based query (objects inside the video), as well as feature based (technical specifications of the video i.e. frame rate, segment change etc.). Various models have been suggested by different researchers, based on relational, hierarchical and object oriented concepts. The two major modelling schemas are: Annotation Dependent Models: These models heavily depend on hierarchical or relational databases. In these type of models, some textual data (also known as signatures or metadata) about the contents of video are embedded into the video data. Usually an annotator is required to write the captions, but in some models dynamic text can be generated from the audio. VidIO[1], VANE[2], Video-STAR[3] and Media Object [4]are the …
