Description

This item was taken from the IEEE Conference ' A Video Manager for Relational Stream Processing Systems ' Video streams are increasing by the development of network environments and price reduction of camera devices. Therefore needs of applications for querying video streams such as surveillance systems are on the increase. Meanwhile, relational stream processing systems have been researched for querying tuple streams. It is hard to deal with video streams by relational stream processing systems because video streams have time dependency which tuple streams do not have. In this paper, we propose a video manager for relational stream processing systems to integrate video streams and tuple streams. It can be used to query video streams using relational operators by relational stream processing systems and we can obtain resulting video data using RTSP. A video manager manages video data as MPEG-4 files so that they can be played easily by common media players. Finally we implemented a prototype system and evaluated its performance.
