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

摘要

The present invention for recording an image by generating the image data converted by using the image compression standard, and select the necessary part of the transmission from the image data (hereinafter referred to as "FOI") selected image data in the monitoring area in a range IEEE and pluralities of the camera to transmit using the 1394 interface and digital to give a dynamic priority for the plurality of cameras, respectively, and receives and stores transmitted the FOI according to the priority using the IEEE 1394 interface from the plurality of cameras wherein relates to a video surveillance system using the IEEE 1394 interface is a storage device. ; According to the invention, a plurality of surveillance cameras connected to a digital video surveillance When configuring the system surveillance camera node itself small-capacity storage medium built using the priority-based (priority-based) bus control to use the IEEE 1394 interface, this loss of data can be done without simultaneously reducing the video surveillance system construction costs by connecting a plurality of surveillance cameras in the network through, and may store the collected image data efficiently. It can also effectively perform the operation of searching, browsing, and so on of the stored image data. In addition, configured to store to create the FOI image encoding and transmitting from each camera to improve the disadvantage that the load on the conventional video surveillance system has been focused on the side digital storage device and the digital storage device is simply received in order of preference the FOI from each camera it is possible to reduce the load on the digital storage device. ; IEEE 1394, a video surveillance system, ensuring bandwidth, priority, message, network,
