Embodiment Construction

[0032] Next, an embodiment of an error monitoring method for a digital video recorder according to the present invention will be described in detail with reference to the accompanying drawings.

[0033] image 3 Shown is a schematic diagram of the structure of a digital video recorder suitable for the present invention. For example:

[0034] Above-mentioned digital video recorder is made up of following several parts: multimedia signal processing section 20, on-screen display (OSD) generation section 21, microcomputer 22, multimedia digital signal codec 23, hard disk (HDD) 24, error detection section 25, and interface section 26.

[0035] On the other hand, in the above-mentioned multimedia signal processing unit 20, each camera video signal received from the surveillance camera is displayed on the display screen through digital signal processing. The above-mentioned microcomputer 22 controls the above-mentioned multimedia digital signal codec (codec) 23 to capture the abov...

Abstract

The invention relates to a method for monitoring errors in a digital recorder. The invention is characterized in that: in a digital video recorder(DVR) connected with a monitoring camera, an error-monitoring mode is set; after an image cycle recorded in recording media such as a hard disk etc. is read, image color and brightness compositions of the current camera recording are compared; if the comparison result, the difference of the color and the brightness composition, exceeds permitted deviation range, the errors of the recording images are identified and displayed and at the same time the corresponding error information is generated and transmitted to an Internet address set in advance so as to allow users in remote place to rapidly determine the fact of the error information through the network.

Description

technical field [0001] The present invention relates to the error (error) monitoring method of digital video recorder (DVR: Ddigital Video Recorder), especially refers to the error (error) monitoring of a kind of digital video recorder recorded in recording media such as hard disk (HDD) after receiving video camera image method. Background technique [0002] figure 1 Represent, general digital video recorder and most surveillance cameras are connected embodiment schematic diagram, give an example and carry out detailed explanation as follows: Most surveillance cameras 100 that are dispersedly installed in each area 1 ˜100n, photographing the object to be irradiated existing in the current region, and sending it to the above-mentioned digital video recorder 200 . [0003] On the other hand, the above-mentioned digital video recorder 200 displays the camera images taken by the receiving surveillance cameras in the display with screens, as follows: in one display screen, 16 c...
