Embodiment Construction

[0034] figure 1 A video processing system according to one embodiment of the invention is shown. refer to figure 1 , the video processing system includes a plurality of cameras 160 connected to a network. The camera 160 may constitute a local area network (LAN), or may be connected to each hub 150 .

[0035] In this embodiment, camera 160 includes an encoder that compresses captured video using a video compression protocol such as MJPEG, MPEG-4, JPEG 2000, or the like. Accordingly, the video camera 160 outputs captured video in a compressed stream format. The camera 160 may be an analog camera 160 or a network Internet Protocol (IP) camera 160 with a resolution of 640×480.

[0036] All the hubs 150 connected to the cameras 160 control connection of data communication according to the IP address of each camera 160 or a unique address of each camera 160, such as a Media Access Control (MAC) address. Each hub 150 is connected to a Gigabit switching hub 140 capable of routing t...

Abstract

A video processing system is provided. The video processing system includes: a camera that compresses a captured video and provides the compressed video; a video preparation unit including a playback server that decodes a moving picture compression stream transmitted from the camera and a video processor that processes a video decoded by the playback server; and a display device that displays a video prepared and provided by the video preparation unit. Accordingly, a video captured and compressed by a camera is prepared by decoding, and the video is configured with various output conditions so as to be displayed on a display device. This, in comparison with the convention method in which a required video is decoded and displayed whenever a video display condition changes, the required video can be rapidly displayed within a short period of time, and videos captured by a plurality of cameras can be displayed on one image on a real time basis while maintaining a maximum frame rate of the cameras without restriction of the number of cameras. Therefore, there is an advantage in that a specific video can be zoomed in, zoomed out, or panned on a real time basis at the request of a user, thereby improving a usage rate and an operation response of the video processing system.

Description

technical field [0001] The present invention relates to video processing systems and video processing methods, and more particularly to video processing systems, video processing methods, and methods of processing video signals between servers to decode video captured by multiple cameras in preparation for display . Background technique [0002] The unattended surveillance system is used to output video data collected by closed circuit cameras and to store the video data in a recording device. In order to effectively control and utilize the unattended surveillance system, a display device is required to effectively inspect and monitor the video data provided by multiple cameras scattered in many locations. [0003] To this end, Korean Patent Registration No. 10-0504133 entitled "Method for controlling plural images on a monitor of an unattended monitoring system" discloses a conventional method. In this method, an image area displayed on a display device is divided into mu...
