Embodiment Construction

[0013] This method involves the problem of how to directly store video streams with diverse sources as a server. Through this method, the video output from multiple video devices can be viewed on the same client, and the multi-format streams can be re-advanced with video information. And encapsulate it into "block data", and then "directly store" it on the hard disk, which meets the needs of monitoring clients to quickly retrieve video and improves the efficiency of business personnel. like figure 1 As shown, the design diagram of multi-stream data direct storage has 6 elements, namely front-end video equipment, central server, forwarding\storage server, network switch, monitoring client and database server.

[0014] Among them, the video stream generated by the front-end video equipment is connected to the video center server; the video center server unpacks and decomposes the video stream through built-in modules such as forwarding and storage, extracts the video stream data...

Abstract

The invention provides a unified processing and storage method for multi-mode security and protection videos. The method comprises the following steps: (1) a front-end access device, a central scheduling server, a forwarding / storage server, a monitoring client, a database server and the like firstly access the same network via a network switch; (2) a non-network camera is connected to a hard diskvideo recorder, and these video devices establish connection with a central scheduling platform through the network switch; (3) the central scheduling platform begins to send a data request instruction to the camera, the forwarding / storage server firstly receives, re-extracts and packages code streams, then performs code stream distribution and meanwhile directly stores the real-time packaged codestreams on a monitoring hard disk in the form of data blocks; and (4) when a monitoring client needs to call the historical videos, the monitoring client accesses the database at first, and inputs the time period information of the pre-query video and the corresponding camera ID according to the need.

Description

technical field [0001] The invention relates to the field of security video monitoring, and mainly solves how to encapsulate video front-end video streams with diverse sources according to the same standard stream format and directly store them in a server, so as to realize unified review, control and download of video streams by video clients. The problem. Background technique [0002] In recent years, with the rapid development of digital image processing technology and digital circuit technology, the digitization and processing of image signals has become more common. In the field of video surveillance, the video compression coding format has experienced M-JPEG, H.263, MPEC4 to H With the development of .264, the video equipment produced by this technology is rapidly updated, and supports dual-stream and multi-stream video transmission forms. There are video equipment manufacturers in the market each occupying one side, sharing a field in the security industry. [0003]...
