In the present embodiment, the pause instruction can main broadcaster assigned in data collection client.In addition,
In other application scene, data collection client can also be directed to specific situation, automatically generate pause instruction.
In one embodiment of the application, data collection client preferentially can obtain straight from camera and microphone
Multicast data, then can be detected to the live data of acquisition, so as to judge currently whether generate pause instruction.Specifically,
When the picture all same that the live data that the data collection client is gathered in the first specified duration is shown, Ke Yisheng
Into pause instruction.In the present embodiment, described first when to specify duration can be set in advance in data collection client
Long, the duration can be adjusted according to actual scene.For example, described first specifies duration to be 10 seconds, then at 10 seconds
In in, if the picture that camera is collected all is identical, show the model that now main broadcaster shoots possibly off camera
Enclose, do not had tangible live content currently, then data collection client just can automatically generate pause instruction.In this reality
Apply in mode, by judging first the live data gathered in duration can be specified whether identical, so as to judge that described first refers to
Whether the picture of displaying is identical in timing is long.
In one embodiment of the application, if camera goes wrong, it is impossible to collect the live data of main broadcaster, that
Data collection client can not just get live data.So, in the present embodiment, when the data collection client
When second specifies and can not collect live data in duration, pause instruction can also be generated.Described second specifies duration can
To be duration set in advance in data collection client, the duration can be adjusted according to actual scene.For example, described
Two specify duration to be 3 seconds, then in 3 seconds, when data collection client can not collect live data always, just may be used
To generate pause instruction, to provide live data by live pause device.
Also referring to Fig. 3, in the present embodiment, when live pause device receives the pause instruction, just may be used
Be used to substituting live data to obtain intercuts video data.The video data that intercuts can be that main broadcaster is advance in data acquisition
The video material stored in client.Video material resource such as can be Video Roundup, advertisement, pictures.It is described
Intercutting video data can uniformly be stored in specified resources bank.The specified resources bank can be file or base
The database set up in data structure.The database is such as can be MySQL, Oracle, DB2, Sybase.
In the present embodiment, live pause device intercuts video data except that can be obtained from specified resources bank, also
It can be read from local cache and intercut video data.In the local cache intercut video data can be it is last or
That is read during preceding pause several times intercuts video data.So, live pause device directly reads from local cache and intercuts video
Data, it is possible to increase the reading speed of data.
In one embodiment of the application, in local cache or specified resources bank intercut video data can with when
Intermediate node is associated, and the timing node, which is used to characterizing, described intercuts the timing node that video data the last time is read.For
The video data that intercuts played in pause will not be repeated in a short time, can selectively be read based on timing node slotting
Broadcast video data.Specifically, live pause device can be from the when segmentum intercalaris for exceeding specified time threshold apart from current time node
The intercutting to obtain in video data of point association intercuts video data for push to the direct broadcast server.The specified time
Threshold value can be the duration pre-set.For example, the specified time threshold can be 12 hours.So, within 12 hours,
The same video data that intercuts just will not be repeated playing.In specified resources bank or local cache, intercutting video data can
To be ranked up according to timing node, timing node is closer to current time node, and the position of sequence can be more rearward.Specifically
Ground, referring to Fig. 4, intercutting video data can be stored according to array.In array, more forward intercuts video data,
Corresponding timing node is more long apart from current time node.For example, as shown in figure 4,3 are had in local cache intercuts video
Data, correspond to 04 minute July 13 day 12 point in 2017,14 minutes July 14 day 15 point in 2017, July 16 day 5: 08 in 2017 respectively
Divide these three timing nodes.So when video data is intercutted in reading from local cache, first in array can be inserted
Broadcast video data to read out, be used as the data that will be pushed to direct broadcast server.Further, it is also possible to according to current time node
With the specified time threshold, determine that the multiple of candidate intercut video data.For example, current time node is in July, 2017
16 days 12 points, the specified time threshold be 24 hours, then candidate's intercuts the corresponding timing node the latest of video data
For 12 points of July 15 day in 2017, then it is later than intercutting video data and just cannot repeating playing for the timing node.Therefore, such as Fig. 4
In shown, only first, which intercuts video data and second, intercuts video data and can intercut video data as candidate.Then,
Can from candidate it is multiple intercut video data in random read take one, be used as the data that will be pushed to direct broadcast server.
In one embodiment of the application, in the pause instruction that data collection client is sent, duration can also be included
Information.The effect of the duration information is：It is described after the duration that the duration information is characterized since current time
The live data of the data collection client collection is played in direct broadcast server pause.For example, the duration information is 10 seconds, that
Indicate that, at the time of the pause instruction is generated, then by 10 seconds, data collection client just stopped from shooting
Live data is obtained at head and microphone, correspondingly, direct broadcast server, which just suspends, plays the data collection client collection
Live data.The duration information is used to live pause device and reserves the acquisition time for intercutting video data, so that
So that being played in pause after current live video, video data can be intercutted in seamless connection.In the present embodiment, it is live
Pause device can detect current average speed of download, and the average speed of download can be live pause device from specified money
The average speed of resource is downloaded in the storehouse of source.So, the duration characterized based on the average speed of download and the duration information, from
And can determine in the duration information, the target data download that live pause device can be downloaded.For example, described average
Speed of download can be 2M/s, and the duration information can be 10 seconds, then the target data download can be 20MB.
In present embodiment, live pause device can according to the fixed cycle from specified resources bank the less detection number of downloading data amount
According to bag.For example, live pause device every 10 seconds, can download 1MB probe data packet from specified resources bank, and under
The speed of set detection packet, to calculate current speed of download.Then, can be when will be current after pause instruction is received
The given amount of data speed of download averaged calculated before quarter, so as to obtain current average speed of download.In this reality
Apply in mode, live pause device can be obtained and downloaded with the target data after the target data download is determined
What amount was adapted intercuts video data.Wherein, intercut video data and be adapted to refer to target data download and intercut video
