Title:
DIGITAL VIDEO SYSTEM USING NETWORKED CAMERAS
Document Type and Number:
WIPO Patent Application WO2001069405
Kind Code:
A8
Abstract:
A digital video system (20) including a computer (22) connected via a network (28) to a number of video servers (26) and cameras (24). The computer (22) includes a program that provides a grid of display windows, each of which displays an image received from the camera associated with that window. The program sequentially polls each camera, accessing and displaying an images from the camera in its associated window. The program can access the cameras (24) at different frame rates. The program stores image streams in a single file, concatenating each successive image onto the end of the file. The file is then indexed using SOI and EOI markers to permit fast access to individual images within the file. The program can monitor received video and automatically start recording upon detecting motion within the video stream. Motion detection is implemented by comparing color component values for pixels from different images.
