Embodiment Construction

[0013] This method involves the problem of how to directly store video code streams from 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 code streams can be re-advance the video information. It is packaged into "block data" and then "directly stored" on the hard disk, which meets the needs of monitoring clients to quickly retrieve videos and improves the efficiency of business personnel. Such as figure 1 As shown, the design diagram of multi-stream data direct storage has a total of 6 elements, which are 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 th...

Abstract

The invention relates to a multi-code-stream video data direct storage method, which comprises the steps that (1) a front-end access device, a central scheduling server, a forwarding / storage server, a monitoring client, a database server and the like are connected to the same network through a network switch at first; (2) a non-network camera is connected to a hard disk video recorder, and the video equipment establish connection with the central scheduling platform through the network switch at the same time; (3) the central scheduling platform sends a data request instruction to the camera, the forwarding / storage server firstly receives code streams and carries out extraction and package again, then carries out code stream distribution, and directly stores the code streams, which are packaged in real time, on a monitoring hard disk in a data block mode at the same time; and (4) the monitoring client accesses to a database at first when requiring to take historical video, and inputs time period information and a corresponding camera ID of the video desired to be queried according to requirements.

Description

technical field [0001] The present invention relates to the field of security video monitoring, and mainly solves how to encapsulate video streams with diversified sources according to the same standard code stream format and directly store them in the 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, video compression coding formats have experienced M-JPEG, H.263, MPEC4 to H With the development of .264, the video equipment produced by this technology can be updated quickly, and it supports dual-stream and multi-stream video transmission forms. The video equipment manufacturers that exist in the market each occupy one side, sharing a field in the security industry. ...
