Dependable multilevel medium storage method

Abstract

The invention provides a reliable multimedia memory method. The method utilizes the concentrative memory mode of a server, starts a DVR local memory when the network fails and re-memorizes in the server after the network recovers. The method has the advantages of good system stability and simple and convenient video management; the video recording file generated when the network fails is uniformly managed in the DVR magnetic disk memory and is automatically uploaded to a stream media server; the method is especially suitable for the user environment in a remote video monitoring platform where the video is extremely strictly required; furthermore, the method reduces the severe requirements which need to be considered by the remote video monitoring system for the user customized record memory strategy.

Description

1. Technical field [0001] The application of the present invention relates to media data storage, in particular to reliable storage of real-time media data in MPEG4 and H.264 encoding formats in the field of remote video monitoring. It is used to ensure the stable operation of the network monitoring platform system of important surveillance video. 2. Background technology [0002] In the field of remote video surveillance, the storage of media data is very important, and the stored historical data may provide users with important clues or evidence. The loss of surveillance video due to factors such as network instability and imperfect video storage strategy will cause significant economic losses to operators and surveillance system users. [0003] The current remote video surveillance platform system usually adopts the following two storage methods: [0004] DVR (Digital Video Recorder) device local storage: With this storage method, the media data is stored locally in the...

Problems solved by technology

[0009] Customize the local storage policy of the current DVR device. If the network is unstable when the alarm condition is not met, the video recording during this period will be lost

This method is difficult to adopt for remote management with a large amount of storage and needs to be backed up

[0010] Server centralized storage: This storage method usually uses a large-capacity disk array, which has the characteristics of large capacity, reliable storage media, easy management and backup, but this method also has its shortcomings, that is, all data needs to pass through the network. In a large-scale video surveillance system, front-end DVR devices are distributed in various network environments, and some even access through the Internet and are subject to the influence of network conditions. The constraints of the network environment and the Internet will greatly increase Therefore, in the process of data transmission, data loss often occurs, which has a negative impact on monitoring, and even loses important video data, affecting the safety and reliability of the entire monitoring
