Abstract

The invention relates to a multi-address remote backup system of a hard-disk based digital video recorder, and belongs to the technical field of designs of hard-disk based digital video recorders. The multi-address remote backup system comprises a hard-disk based digital video recorder body and a body hard disk arranged in the hard-disk based digital video recorder body, and is characterized by further comprising remote storage devices, and a remote storage unit and a remote ISCSI (internet small computer system interface) are arranged on each remote storage device; and an image processing unit and a body ISCSI are arranged on the hard-disk based video recorder body. A central processing unit is arranged on the hard-disk based digital video recorder body, a player or a video interface is arranged on each remote storage device, the players are used for playing image data of the remote storage units, and the video interfaces are used for being connected with external players. The multi-address remote backup system has the advantages of reasonable and simple structure, convenience in use and capability of implementing remote multi-address backup for information of the image data.

Description

technical field [0001] The invention relates to a multi-site remote backup system for a digital hard disk video recorder, which belongs to the technical field of digital hard disk video recorder design. Background technique [0002] Digital hard disk video recorder integrates computer technology, network technology, digital video technology and security technology, and effectively realizes the digital high-fidelity storage of analog video in the hard disk inside the hard disk video recorder. It is the embodiment of modern technology and is widely used in remote monitoring, Building intelligence and other fields. [0003] The existing digital hard disk video recorder image content storage depends on the size of the hard disk. Once the hard disk space is full, the user must delete or transfer the image content to free up the hard disk space for the user to store new image content. And when the hard disk is damaged, it is very difficult to recover data, often resulting in irre...
