Title: BREAKPOINT-RESUME TRANSMISSION METHOD AND DEVICE FOR SURVEILLANCE VIDEO
Abstract:
Disclosed in the embodiments of the present application are a breakpoint-resume transmission method and device for a surveillance video, applied to a client. The method comprises: obtaining a download instruction; determining whether the breakpoint identifier exists, which corresponds to a start time and an end time carried in the download instruction; if so, according to the start time, finding part of a surveillance video presently being downloaded, corresponding to a target surveillance video; according to said surveillance video part, determining the download breakpoint time of the target surveillance video; sending the download breakpoint time and the end time to a target monitoring device for storing the target surveillance video, so that the target monitoring device sends, to the client, video code streams of the target surveillance video from the download breakpoint time to the end time; and receiving and saving the video code streams. The present solution can perform breakpoint-resume transmission from the download breakpoint time, when the download of a target surveillance video is interrupted and is performed again, without the need to re-download the target surveillance video from the start time, saving much downloading time and traffic.
