DIGITAL VIDEO SURVEILLANCE SYSTEM USING IEEE 1394 INTERFACE AND METHOD FOR PROVIDING BANDWIDTH USING THEREOF

摘要

The present invention generates the image data converted by using the video compression standard by taking a picture within a surveillance zone of a predetermined range, and (hereinafter referred to as "FOI") is to select the necessary portion selected image data from among the image data for IEEE and a plurality of cameras that transmitted using the 1394 interface, given the dynamic priority for said plurality of cameras, respectively, and use the IEEE 1394 interface from the plurality of cameras digital receiving and storing transmitted the FOI in accordance with the priority relates to a video surveillance system using the IEEE 1394 interface is a storage device. ; According to the invention, by using the IEEE 1394 interface, when connecting a plurality of monitoring camera constituting a digital video surveillance system using a built-in small-capacity storage medium, the monitor camera node itself, and priority-based (priority-based) the bus control by at the same time without a loss of data through connection to a plurality of surveillance cameras to the network and to reduce the cost of building a video surveillance system, and store the collected image data efficiently. In addition, it is possible to effectively perform the operation of the search, such as browsing of the stored image data. Also generates a coded and transferred FOI image from each camera to improve the disadvantage was the load is concentrated on the side digital storage device in the conventional video surveillance system and configured to store the received first according to the FOI from simply each camera in the digital storage device Rank It can reduce the load on the digital storage device. ; IEEE 1394, a video surveillance system, the bandwidth secured, priority, message, network
