Abstract: A camera apparatus having a digital image processing function for an analog transmission network is provided. The camera apparatus divides each of frames of first resolution digital image data into N equal regions, converting each frame of the digital image data into N fields by interlacing the regions in order of region numbers, and transmitting the N fields through the analog transmission network. High resolution image data of HDTV class created by the camera apparatus can be reproduced on an image display apparatus by using analog transmission networks laid for transmitting analog image data conforming to the analog NTSC, PAL, or SECAM standard without any change.

Abstract: Provided is a method of restoring and/or reconstructing a super-resolution image from low-resolution images compressed in a digital video recorder (DVR) environment. The present invention can remove a blur of a video sequence, caused by optical limitations due to a miniaturized camera of a digital video recorder monitoring system, a limitation of spatial resolution due to an insufficient number of pixels of a CCD/CMOS image sensor, and noises generated during image compression, transmission and storing processes, to restore high-frequency components of low-resolution images (for example, the face and appearance of a suspect or numbers of a number plate) to reconstruct a super-resolution image. Consequently, an interest part of a low-resolution image stored in the digital video recorder can be magnified to a high-resolution image later, and the effect of an expensive high-performance camera can be obtained from an inexpensive low-performance camera.

Abstract: The present invention discloses a control technology for remote control of security cameras, and more particularly, to a method of providing virtual Joystick environment as if Joystick was used on a computer, and system thereof. A selected region is set on a computer monitor.

Abstract: A dual moving picture compression method that executes both moving picture compression for displaying a moving picture with high picture quality in real-time and moving picture compression for recording the moving picture at a high compression ratio and a low speed. A network camera and a network DVR are employed. The network camera includes two moving picture encoders that dually compress an image to transmit them to a network. The network DVR receives the dually compressed image to display the image on a monitor in real time and simultaneously records the image at a high compression ratio and a low speed. Accordingly, the requirements for teal-time moving picture display and long-term recording can be simultaneously satisfied.

Abstract: An emergency voice communication technique through the Internet using a VoIP (Voice over Internet Protocol) Internet phone between a central control center and a digital video recorder or between remotely located digital video recorders. The operator of the digital video recorder immediately calls the Internet phone of a predetermined remote workstation only by lifting the handset of the Internet phone connected to the digital video recorder when an alarm event is generated in the digital video recorder. If an alarm event occurs in the remote workstation, the operator of the remote workstation immediately calls the Internet phone of the digital video recorder by lifting the handset of the Internet phone connected to the remote workstation. VoIP communication between remotely located digital video recorders can be carried out through a network or the Internet using Internet phones connected to the digital video recorders.

Abstract: A network digital video recorder system includes a plurality of network cameras, each of which is embedded with a switching hub that transmits a compressed video data packet from the network camera to the Ethernet. The switching hub embedded in the network camera multiplexes a compressed video data packet produced by the network camera, and a compressed data packet output by another (e.g., adjacent or neighboring) network camera, to up-link the multiplexed data packets to yet another neighboring network camera. Accordingly, video and audio data can be transmitted to a network digital video recorder through an Ethernet without cascading multiple dedicated hubs.

Abstract: The present invention discloses a multi-screen technique to display multi-channel images captured and transmitted from a multiple of cameras on a single monitor without the loss of resolution for each picture even if a multiple of images are displayed simultaneously.

Abstract: A method and apparatus for ensuring that the computer system does not fail to boot under any circumstances includes an invisible storage region that backs up the operating system, BIOS set-ups, and registry files for booting. The invisible storage region cannot be accessed by a user or the operating system and so is not subject to damage in the event of an abnormal shutdown due to power failure. Therefore, the computer system never fails to boot due to the damage at the hard disk containing the operating system even under the abrupt interruption of power supply.
