Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the present invention provides a video deletion method capable of specifying a precise time period based on customer needs. Under the file system of the video server, the video file is generated according to a certain period of time; the video file name uses the video generation time, and the video file is composed of the video data and the file index area. The file index area marks the video file every second video The location in the video file, the video file is stored on the storage server; the time period specified by the customer to delete the video is sent to the storage server; the storage server searches for the file containing this time period according to the received time period. During this period, the following s...

Abstract

The invention provides a method and a device for the video management of a video monitoring system. The method comprises the following steps: firstly, enabling each video file to store video streams with preset time length, and the file name of each video file containing the generation time of the stored video streams; secondly, receiving the delete requests of a client end so as to obtain the delete time period corresponding to the video stream to be deleted; thirdly, searching and finding according to the file names of the video files, and finding out the video file containing the video streams at the delete time period as a target file; and finally, judging whether the video streams stored in the target file include non-deleted video streams except the deleted time period or not, if so, copying and storing the non-deleted video streams to generate a new video file and then deleting the target file; otherwise, directly deleting the target file. The invention can precisely delete video files according to the instructions of clients.

Description

technical field [0001] The invention relates to data management technology of a video monitoring system, in particular to a video recording management method and device of a video monitoring system. Background technique [0002] Video monitoring system is an important part of the security technology system. With the rapid development of science and technology, digital video recording technology is becoming more and more mature, and CCD (charge coupled device, charge coupled device) camera technology is also becoming more mature and commercialized. Digital video monitoring system It has become the mainstream technology used in current video surveillance. In the digital video monitoring system, the image content of the monitored place can be transmitted to the monitoring center, so that the situation of the monitored place can be seen at a glance. Another feature of the digital video surveillance system is that it can record all or part of the images and sounds of the monitor...
