The multi-stream video system includes at least one video capturing device and a video monitoring device. Each video capturing device is used for generating a plurality of video streams with different video specifications at the same time. The video monitoring device forms a telecommunication to each of the video capturing devices. When the video monitoring device performs an application operation, the video monitoring device selects and receives at least one video stream from each of the video capturing devices according to a video requirement of the application operation.

Abstract: A surveillance system having a multi-area motion-detection function is described. The surveillance system includes a display, an area selection device, and a threshold input device. The display shows a surveillance video. The area selection device selects a first area and a second area on the display screen. The threshold input device sets a motion-detection threshold of the first area and a motion-detection threshold of the second area. When the result of the motion-detection exceeds the motion-detection threshold of the first area, the surveillance video is stored in a storage medium. When the result of the motion-detection exceeds the motion-detection threshold of the second area, the surveillance video is stored in the storage medium.

Abstract: A monitoring system including N cameras, a digital video recorder (DVR), a monitor, a remote controller, a receiver and a host is provided. N is a positive integer. The N cameras successively shoot N sceneries, and output N successive images accordingly. The DVR receives and stores the N successive images. The monitor displays a monitoring screen. The remote controller outputs a wireless remote signal. The receiver receives the wireless remote signal and outputs a wire transmit signal accordingly. The host controls the monitor to display at least the successive image in the monitoring screen. The host has an on screen display (OSD) program. When the controller receives the wire transmit signal, the host utilizes the OSD program to process the wire transmit signal to become a screen adjusting signal. The host adjusts the monitoring screen according to the screen adjusting signal.

Abstract: A system for processing multimedia data outputs multiple digital data streams of different compressed ratios or types to adapt to multiple limitations of storage spaces and transmission bandwidths, and thus reduce the repetition for processing the digital data streams to save the central processing unit (CPU) resources.

Abstract: The present invention provides an advertising method for a DVR system. First, a monitor display of the DVR system is separated into a main display region and a banner display region. The main display region is used to broadcast a live scene. The banner display region is used to display an advertisement icon provided by an advertiser. The advertisement content can be renewed in real time by the advertiser through the Internet.

Abstract: A system for grabbing images from an IP Camera, the system has a mounted Digital Video Recorder (DVR) and an installed IP Camera Module, the IP Camera Module simulates the behavior of a web page navigator retrieving data from a website when data is requested from an embedded website on the IP Camera to grab instant image data in JPEG image file format from the IP Camera, and then send the image data to the Digital Video Recorder for processing.

Abstract: A remote controller is described. The remote controller can remote control a plurality of electrical equipments, e.g. digital video recorders, simultaneously or respectively. The remote controller includes a signal emitter, a memory, and a plurality of keys. The memory stores a plurality of controller identification codes, and the keys can select at least one of the controller identification codes and the same is sent to the electrical equipments through the signal emitter. The electrical equipment compares the controller identification code with an equipment identification code stored in the electrical equipment when the electrical equipment receives the controller identification code.

Abstract: A surveillance system having auto-adjustment functionality is described. The surveillance system includes a motion detection module and a video processing module. The motion detection module detects real-time video data and determines whether the video data is in a motion status. When the real-time video data is in the motion status, the video processing module records the real-time video data into a storage medium with a first resolution. When the real-time video data is not in the motion status, the video processing module records the real-time video data into the storage medium with a second resolution.

Abstract: A video data process conformation wherein the noise reduction is implemented by a program. The conformation comprises a video decoder and a digital data process system, and a noise reduction program is executed in the digital data process system. The video decoder converts an external analog video data to a digital video data. Then, the digital video data is transmitted into the digital data processing system via a data transmission interface of the digital data processing system, and the noise data of the digital video data is then filtered by the noise reduction program.

Abstract: A document camera with light compensation functionality includes a camera securing to a base. The document camera has an emitting-adjustable light source. A sensor, installed on top of the camera, measures the light in the surroundings and outputs an analog signal. A converter transforms the analog signal into a digital signal. A light-computing unit receives the digital signal and produces a signal including an optimum light condition. A light controller controls the intensity of the light of the emitting-adjustable light source according to the signal including the optimum light condition outputted from the light-computing unit.

Abstract: A method of searching for clip differences in recorded video data of a surveillance system. The method includes the following steps. First, a plurality of first clips are displayed simultaneously on a display. Each first clip displays the same scene but a different time period of the recorded video data. Next, a first clip having the maximum difference compared with adjacent first clips is selected. Next, the time period represented by the selected first clip is further divided into a plurality of time periods and a plurality of second clips are displayed on the display. Each second clip displays the same scene but a different time period of the selected first clip. Subsequent layers of clips are repeatedly divided until the exact time point having the maximum difference is found.

Abstract: A surveillance system and a surveillance method are described. The surveillance system has a video recorder and a video processing module. The video recorder records a scene and generates an original video signal. The scene has an area in need of coverage. The video processing module receives the original video signal. The video processing module performs an interference process on part of the image displaying the area in need of coverage and generates a post-processing video signal for displaying on a display. The interference process prevents the part of the image displaying the area in need of coverage from being identified.
