Problems solved by technology

All the above architectures provide good system support for video surveillance. However, the stability and clarity of video storage is an important guarantee for the quality of surveillance. At present, the storage of video surveillance systems usually has the following deficiencies: the encoding format is relatively fixed; The system adopts a data storage mode based on multi-level pointers, which has problems such as large I / O operations and easy storage fragmentation when storing frame data, resulting in low video storage efficiency and poor retrieval performance, which has become a bottleneck for system performance and scale improvement

Abstract

The invention provides a network storing method. The method comprises the steps of building a global block, a first-stage index area and a data area in a storing device; directly storing video data into the storing device; setting a frame cache and an index cache; storing the frame data and the index information into the frame cache and the index cache in advance during storing the video; performing organization management for the video information through an index tree. The method is a network based network method; large data quantity can be stably stored and quickly and accurately searched; the practicability and reliability are ensured.

Description

technical field [0001] The invention relates to network storage, in particular to a video data storage method. Background technique [0002] In recent years, with the continuous development of video compression technology and the improvement of network bandwidth, the video surveillance system has been favored by the field of security monitoring for its small size, integration, strong operability, customization, easy maintenance, and accessibility. great welcome. In addition to real-time monitoring of on-site conditions, real-time video of the front-end site or emergency alarm events during the unmanned monitoring period can also be read and analyzed after the event. At present, there are many storage systems to support the video surveillance system. Among them, DAS is suitable for the situation where the servers are scattered geographically, and the storage device is directly connected to the server through SCSI interface or fiber channel. SAN transmits data blocks to the...
