It is ranked up in the downloading task quantity, determines the dispatching priority of each link.Specifically, client can real-time geo-statistic
The corresponding downloading task quantity of video clip that each link is completed completes the download of a video clip in each link
When, it may be determined that the link completes the corresponding downloading task of a video clip, and the piece of video that can be completed to the link
The corresponding downloading task quantity of section adds 1；It is ranked up so as to be based on the corresponding downloading task quantity of each link, it such as can be by
Each link is ranked up according to the sequence of downloading task quantity from high to low, to determine each link according to the sequence after sequence
Dispatching priority.Wherein, the corresponding downloading task quantity of link is higher, and the dispatching priority of the link is also higher.
It should be noted that client can also in other orders be ranked up each link, can such as appoint according to downloading
The sequence of business quantity from high to low is ranked up each link, and the corresponding link of downloading task data highest is determined as dispatching
The link of highest priority, the embodiment of the present invention are not restricted this.
Step 212, by the highest link of dispatching priority, to the highest video of current priority in the video data
Segment is downloaded.
In embodiments of the present invention, optionally, it further includes：According to the corresponding reproduction time of each video clip, determine respectively to regard
The corresponding priority of frequency segment.For example, can be calculated according to the distance of video clip to be downloaded and current time, determine
The priority of each video clip；And the video clip of highest priority can be downloaded using optimal link.
Wherein, it is described by the highest link of dispatching priority, it is regarded to current priority is highest in the video data
Frequency segment is downloaded, and can be included：In the downloading process of the video data, determine that the current priority is highest and regard
The download link of frequency segment；Judge whether the download link is the highest link of dispatching priority；If so, continue using institute
Download link is stated to be downloaded the highest video clip of the current priority；Otherwise, it is the current priority is highest
Video clip switches to the highest link of dispatching priority from the download link and is downloaded.
In the concrete realization, client can be according to the playing sequence of video clip each in video data, to currently treating down
