Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0028] Such as figure 1 Shown is a structural diagram of the storage and fast positioning system for time-overlapped video streams of the present invention. The system 100 includes: a video stream storage server 10 and a video stream location server 20 .

[0029] The video stream storage server 10 includes a logical volume division module 20. The logical volume division module 20 divides a video storage block device, divides a storage space for each video stream in the video storage block device, and establishes a storage space for each video stream in the storage space. Segment index table and time index table.

[0030] Wherein, the segment index includes the start time and end time of the video stream in a certain period of time and the index number of the segment, and the time index inclu...

Abstract

The invention discloses a time-overlapped video stream rapid-positioning method and a time-overlapped video stream rapid-positioning system for video monitoring. The method comprises the following steps that 1, a video stream storage server divides a video storage block, divides storage spaces in video streams, and establishes a segment index table and a time index table for each video stream in the storage space; 2, when positioning a video stream of a time period, a video stream positioning server acquires a segment index number consistent with a condition according to the starting time and the ending time of the time period, positions a target segment index according to the segment index number consistent with the condition, acquires the starting address and the size of the storage space for the video stream from the time index table according to the target segment index, and acquires the video stream according to the starting address and the size of the storage space. According to the method and the system, the problem that video streams of the same time period cannot be played or downloaded is solved.

Description

technical field [0001] The invention belongs to the technical field of computer information storage, and in particular relates to a fast positioning method and system for time-overlapped video streams used in video monitoring. Background technique [0002] With the continuous deepening of the "Skynet Project" and "Safe City" construction, the upgrading of video security monitoring technology, the change of new technology and the future development have attracted more and more attention from all walks of life. Technologies such as high-definition video, video storage, and intelligent video analysis have become the main aspects of the current video technology development. [0003] At present, surveillance cameras have spread all over every street in China, monitoring and recording around the clock. While improving social security, generating massive amounts of video information and monitoring thousands of monitoring platforms will consume a lot of manpower, material resources...
