Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
First, simple introduction is done to Video transmission system.In Video transmission system, usually can comprise main controlled node (or being called main control server) and multiple branch node (or being called branch server).For being distinguished by each branch node, these nodes are called first node, Section Point etc.For certain Video transmission system, the control centre of this system is located at A city, is equipped with branch server in B city, C city etc.Therefore, the server in A city can be described as main controlled node, B, C two the server in city can be described as branch node.
Wherein, main controlled node is the center of whole Video transmission system.Main controlled node, for receiving the video sent from each branch node, carries out follow-up process to video, as editor etc.When there being new node to join this system, the information of the node newly added also can be sent to other branch nodes by main controlled node.
Wherein, in such a system, branch node can be divided three classes:
The first kind: such branch node is responsible for gathering video, and sends the video collected to main controlled node, but not as transit node.That is, the branch node of the type cannot be other branch nodes forwarding video in system.
Equations of The Second Kind: the not responsible collection video of such branch node, can only as transit node.That is video from other branch node receiver, video, and can be transmitted to other branch node or directly send to main controlled node by the branch node of the type.
3rd class: such branch node is responsible for gathering video, the video collected directly can be sent to the branch node of main controlled node; Or such branch node also can be used as transit node, also namely the video that other branch nodes send can be transmitted to other branch node or directly send to main controlled node.
For the node of above-mentioned Equations of The Second Kind and the node of the 3rd class, because they have forwarding capability, so can forward node be referred to as.
For two in system node first node and Section Point, when first node sends video file to main controlled node, video file can be sent to main controlled node by any transmission link between first node and main controlled node by first node.In order to alleviate the transmission burden of certain transmission link, improving video transmission rate, in embodiments of the present invention, the video file that first node sends being assigned to different transmission links and sending to main controlled node.Below in conjunction with specific embodiment, the solution of the present invention is elaborated.
As shown in Figure 1, method for processing video frequency of the present invention, comprising:
Step 11, video file is divided at least two sub-video files.
In this step, mainly fragment process is carried out to video file, described video file is divided at least two sub-video files.According to HLS (HTTP Live Streaming) agreement, video is made up of in chronological order multiple ts (Transport Stream, transport stream) fragment file.Therefore, based on this, video can be split.Concrete, according to the type of video file, video file can be divided into the sub-video file varied in size.Such as, video file can be divided into the sub-video file of multiple 512k size.Being divided into multiple sub-video file by video file being done fragment process, conveniently can distributing corresponding video file between the first transmission link and the second transmission link.
Step 12, to obtain by first node to the information of the first transmission link of main controlled node with by the information of described first node to the second transmission link of described main controlled node.
Wherein, because the acquisition of bandwidth availability ratio is comparatively convenient, therefore, the bandwidth availability ratio of described first transmission link and the bandwidth availability ratio of described second transmission link is mainly obtained in this step.Certainly, other parameter can also be utilized as the information of the first transmission link and the second transmission link.

Determine whether the first transmission link and the second transmission link meet preset requirement according to the bandwidth availability ratio of the first transmission link obtained in step 12 and the bandwidth availability ratio of the second transmission link.Wherein this preset requirement can be bandwidth availability ratio higher limit, such as, be 70%.Through determining, the bandwidth availability ratio of the first transmission link is the bandwidth availability ratio of the 60%, second transmission link is 65%.This shows, the bandwidth availability ratio of the first transmission link and the bandwidth availability ratio of the second transmission link are all less than above-mentioned higher limit, so described first transmission link and described second transmission link meet preset requirement.
In this step, first according to the bandwidth availability ratio of described first transmission link and described second transmission link, the transmission allocation of parameters between described first transmission link and described second transmission link is obtained.Wherein, described transmission allocation of parameters is the ratio of the bandwidth availability ratio of described first transmission link and the bandwidth availability ratio of described second transmission link.Due to bandwidth availability ratio acquisition more for convenience, therefore, utilize the ratio of the bandwidth availability ratio of the bandwidth availability ratio of the first transmission link and the second transmission link as convenience and the practicality of transmitting allocation of parameters and can improve this programme.Then, according to described transmission allocation of parameters, described first node utilizes described first transmission link to send corresponding sub-video file to described main controlled node, utilizes described second transmission link to send corresponding sub-video file to described main controlled node.
By obtaining the transmission allocation of parameters between the first transmission link and the second transmission link, the sub-video file that the first transmission link and the second transmission link can transmit can be obtained more accurately, thus further improve the efficiency of transmission of video.
Such as, between first node and main controlled node, comprise link 1, link 2, link 3, link 4.Wherein, the bandwidth availability ratio upper limit is 80%.The bandwidth availability ratio of its link 1, link 2, link 3, link 4 is respectively 85%, 10%, 30%, 20%.Through confirming, link 1 can not meet transmission requirement, so link 1 is unsuitable for transmission of video; Link 2, link 3, link 4 meet transmission requirement, can be used for transmission of video.The ratio of the bandwidth availability ratio of link 2, link 3, link 4 is 1:3:2, therefore, according to this ratio, distributes corresponding sub-video file, then utilized by sub-video file link 2, link 3, link 4 to transmit respectively at link 2, link 3, link 4.
