Video storing and instant replay system based on IP (identification of position)-SAN (storage area networking) direct storage technology

Abstract

The invention relates to a video storing and instant replay system based on an IP (identification of position)-SAN (storage area networking) direct storage technology. Video data required to be stored adopts a sequence block storage preferential strategy to be stored into an IP-SAN storage system. When a video is replayed, the video data in the IP-SAN storage system is read by iSCSI (internet Small Computer System Interface) protocol commands so as to carry out replaying after initial addresses of video data blocks in an IP-SAN are obtained. The system can realize automatic retrieval and intelligent identification of specific pictures, is huge in synchronous data processing quantity, approximately realizes a real-time network monitoring function in a way that a non-real-time video is replayed by delaying within one second, eliminates a streaming media server, simplifies a system structure and reduces the management cost of the system.

Description

Technical field [0001] The invention relates to a video system, in particular to a video storage and instant playback system. Background technique [0002] In the security monitoring system, the monitoring video is packaged into video files by time period, and the length of the video clips contained in each video file is about 2 minutes to 30 minutes, or even longer. [0003] The Hawkeye system is a computer system used in cricket, tennis and other sports to track and record the path of a ball and display a graphical image of the actual path recorded, as well as to predict the future path of the ball. This system consists of 8 or 10 high-speed cameras, four computers and a large screen. First, use computer calculations to divide the three-dimensional space in the playing field into measurement units calculated in millimeters; then, use high-speed cameras to simultaneously capture the basic data of the tennis flight trajectory from different angles; and then use computer cal...

Problems solved by technology

[0004] The existing security monitoring system has the following technical problems: Since the duration of each video file cannot be shortened to the second level, when a major incident occurs, the existing technology cannot immediately replay the event video that occurred a few seconds ago; When the surveillance video system plays back video recordings, it can only rely on human eyes to search and identify the screen. When it is necessary to search for specific events in multiple video recordings and for a long period of time, this manual retrieval method is inefficient. And when a specific event occurs for a short time, even only a few seconds, it is easy to miss in the manual retrieval process; the existing "Eagle Eye System" or the "immediate playback system" during the live broadcast of events are all based on the application field of TV broadcasting Its main purpose is to achieve slow playback of three-dimensional images and action clips, and the hardware devices used in these systems are quite expensive, dozens or even hundreds of times the price of cameras in ordinary security monitoring systems, and such systems are only Suitable for application environments with a small number of videos
