Time started is consistent, then merges described two video files according to the time；If the video in video file after merging
Duration is more than that preset video file duration divides the video file after merging then according to the video file duration.
Further, above-mentioned steps are merged widenable to multiple video files.
For example, it is assumed that there are three video file W1, W2 and W3, the videos of W1 a length of 10 minutes when preset video file
Time started and video end time are respectively 10:00:00 and 10:02:00, the video time started and video end time of W2
The video time started and video end time of respectively 10:08:00 and 10:15:00, W3 are respectively 10:02:00 and 10:08:
00.The video length of these three video files is respectively less than 10 minutes, and the video time started of the video end time of W1 and W3
Unanimously, the video end time of W3 and the video time started of W2 are consistent, thus can according to the sequence of W1, W3, W2 by these three
Video data in video file merges, the video time started of the video data after merging and video end time difference
For 10:00:00 and 10:15:00, video length is 15 minutes, has been more than 10 minutes, then the video data after merging has been divided into two
A video file is saved, the video time started and video end time of first video file be respectively 10:00:00 and
10:10:00, the video time started and video end time of second video file are respectively 10:10:00 and 10:15:00.
Client or decoder in the above process can be different client or decoder, passive recording service device for
The video data at the same time point of same video monitoring apparatus only stores portion.As long as that is, video monitoring apparatus
One section of video data was requested, then when other subsequent clients or decoder request this section of video data, can directly from
It is obtained in passive recording service device.
