Optionally, the method for the present embodiment can also include: that the video data of preset data amount is being stored as a view
When frequency block, the corresponding monitor mark of record video block；Step S130 may include: when the carrying for receiving target device transmission
When having the query video instruction of Target Monitor mark and time segment information, determine that Target Monitor identifies corresponding video block
In, video block that corresponding recording time and time segment information match.
In an implementation, since server is generally as server cluster, that is, cloud, and the monitor that cloud can be accessed
Quantity is also huge, therefore server is in addition to storing the video block received recording time corresponding with video block
Except, the monitor mark of the corresponding monitor for recording the screen block of video block can also be stored.At this point, target is set
The query video that preparation is sent instructs in addition to carrying time segment information, can also carry Target Monitor mark, that is, show
User wants to check the video data which monitor is recorded period in which.Server is receiving target device transmission
When query video instructs, it can determine that Target Monitor identifies in corresponding video block, corresponding recording time and period believe
The matched video block of manner of breathing.
In the present embodiment, above-mentioned to only provide a kind of mode of simple inquiry video, one kind is provided below more
The mode of specific inquiry video.Optionally, it will need that the FUSE of carry is file system mounted sets to target in target device
After in standby, further includes: according to the recording time of each video block of storage, period letter to be selected is sent to target device
Breath；The time segment information carried in query video instruction is that target device passes through selection instruction in time segment information to be selected
The time segment information selected.
In an implementation, it will need after the FUSE of carry is file system mounted into target device in target device, clothes
Being engaged in device can be to the corresponding query video service of target device offer.As shown in figure 3, the monitor of front end uploads video data
To server, these video data cuttings can be video block by server, and to be selected according to the generation of the recording time of video block
The time segment information such as directory information selected.After the directory information is sent to target device, target device can be in target device
Directory information is shown in the FUSE file system of middle carry.For example, directory information is sent to user A or user B.
When user is after checking directory information, if there is wanting the video checked, then can click in directory information
Target directory mark, target device, which can trigger, at this time generates query video instruction, the period letter carried in query video instruction
Breath is the target directory mark selected in directory information by selection instruction.It should be noted that being different from offer video
The video that query window allows user's input to want to check in the present embodiment is allowed by providing time segment information to be selected
User has whole understanding to the video data stored in server, may then pass through and time segment information to be selected is selected to select
Select out the corresponding time segment information of the video for needing to inquire.
Optionally, when above-mentioned directory information has hierarchical relationship, i.e., more than one layer of single catalogue includes under top-level directory
Second-level directory, second-level directory can also include time second-level directory etc., can inquire video by following methods.Correspondingly, each
In recording time include at least one rank period information, the period information of at least one rank include year information, the moon
One of information, day information are a variety of.Wherein, year information, month information, day information can be freely combined, such as combination adult
The mode of month information, moon day information.Year month information such as 1701,1702,1708 can indicate in January, 17,2 months 17 years, 17 years 8
Month.
According to the recording time of each video block of storage, the step of sending time segment information to be selected to target device, can
The time segment information of the corresponding whole highest levels of recording time to comprise determining that each video block of storage, by highest level
Time segment information be sent to target device as time segment information to be selected.
In an implementation, when user logs on to server by way of Telnet in target device, server can
The FUSE of carry in target device will be needed file system mounted to target device.It is needed in target device well in carry
After the FUSE file system of carry, the FUSE file system run in server can transfer storage by dedicated interface
The recording time of each video block.Then, the FUSE text run in the recording time for each video block for transferring storage into server
After part system, the FUSE file system run in server can generate highest based on the recording time of each video block of storage
The period information of rank.The time segment information of the highest level can be default when user log on to server first have to
The catalogue layer that user shows.
Specifically, for example, there is 5 video blocks in server, their recording time is 20170122 respectively,
20160507,20160405,20170509,20160825, i.e., they respectively on January 22nd, 2017, on May 7th, 2016,
On April 5th, 2016, on May 9th, 2017, on August 25th, 2016 record.It, can respectively will be each when storing recording time
Video block recording year information, month information, day unpack stored.As shown in figure 4, target device login service device,
The FUSE file system run in server obtains the year information of above-mentioned 5 video blocks by preset interface from memory, deposits
It is 2017,2016,2016,2017,2016 that reservoir, which obtains year information in internal queries,.Memory is by query result
It is back to the FUSE file system run in server, the FUSE file system run in server is based on internal logic, to upper
It states year information and carries out identical entry merging, obtaining this 5 video blocks is recorded 2017 and 2016.So
When the time segment information of highest level is year information, the top-level directory generated according to year information includes 2017 and 2016
Year.Target device can be sent by the top-level directory of generation at this time, by the FUSE file system of carry in target device to
User shows top-level directory.After user views top-level directory, the time where the video for oneself wanting to check can choose.
It should be noted that the only schematical description of above-mentioned example.The quantity of the video block stored in server in practical applications
More than 5 pieces, be that description does not carry out exhaustion one by one for convenience here.In practical applications, if recording time is from 2016 4
The moon, it is all existing that the catalogue then generated is at least in April, 2016 to every month continuous between in May, 2017 in May, 2017
Catalogue.
Period letter is carried by what the FUSE file system of carry in target device was sent when receiving target device
When the query video instruction of breath, the step of determining the video block that corresponding recording time matches with time segment information, be can wrap
It includes: carrying time segment information by what the FUSE file system of carry in target device was sent whenever receiving target device
When query video instructs, judge the time segment information that carries in query video instruction whether be lowest level time segment information.
In an implementation, after user sees top-level directory or other level directories, it can choose the catalogue to be entered
To continue the video that inquiry needs to inquire under the catalogue.When user clicks any first class catalogue, target device meeting
The query video instruction for carrying time segment information is sent by the FUSE file system of carry in target device.Wherein, the time
Segment information is time segment information where the catalogue that user clicks to enter.For example, when user from top-level directory in 2017 click into
When entering the second-level directory of top-level directory, the query video instruction for carrying " YEAR 2017 " is generated, and send this to server and refer to
It enables.Period letter is carried by what the FUSE file system of carry in target device was sent when server receives target device
When the query video instruction of breath, judge the time segment information that carries in query video instruction whether be lowest level period letter
Breath.In the present embodiment, the time segment information of lowest level can be day information, i.e., when user is from top-level directory level-one level-one
Selection is got off, when opening bottom catalogue, so that it may determine that the time segment information carried in query video instruction is minimum
The period information of rank.If the time segment information carried in query video instruction is the time segment information of lowest level,
Think that user has found the video of oneself needs.If time segment information is " YEAR 2017 ", when may determine that this
Between segment information be not lowest level time segment information.
If the time segment information carried in query video instruction is not the time segment information of lowest level, it is determined that video is looked into
First level belonging to the time segment information carried in instruction is ask, selection and video in the recording time of each video block of storage
The recording time that the time segment information carried in inquiry instruction matches determines the corresponding whole second level of the recording time chosen
