Abstract

The embodiment of the present invention discloses a method and device for resuming video surveillance video, which is applied to a client. The method includes: obtaining a download instruction; judging whether there is a breakpoint corresponding to the start time and end time carried by the download instruction Identification; if so, according to the start time, find the currently downloaded part of the surveillance video corresponding to the target surveillance video; determine the download breakpoint time of the target surveillance video according to the part of the surveillance video; send the download breakpoint time and end time to the storage target The target monitoring device of the monitoring video, so that the target monitoring device sends the video code stream from the download breakpoint to the end time of the target monitoring video to the client; receives and saves the video code stream. By adopting this solution, when the download of the target surveillance video is interrupted and downloaded again, the download can be resumed from the download breakpoint, and there is no need to re-download from the start of the target surveillance video, which can save a lot of download time and traffic.

Description

technical field [0001] The invention relates to the field of surveillance and security, in particular to a method and device for resuming transmission of surveillance videos. Background technique [0002] At present, monitoring equipment is widely used in various public places to monitor on-site safety. For example, monitoring equipment is generally installed in major shopping malls, office buildings and other places. The early monitoring equipment is generally a closed-circuit monitoring system, which includes front-end camera equipment, back-end host equipment and monitors. Specifically, the front-end camera equipment collects on-site images and transmits them to the back-end host equipment, and displays the surveillance video synchronously through the monitor. Images for the staff to watch the scene in real time to monitor the safety of the scene. [0003] With the rapid development of network technology, monitoring equipment is gradually reformed and upgraded, and funct...
