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, the Video transmission system applied the present invention does simple introduction.In Video transmission system of the present invention, 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.
In order to improve the stability of transmission of video, central scope of the present invention is as follows: when first node sends video to main controlled node, described first node obtains the information of conversion link, and wherein said conversion link comprises described first node, Section Point and described main controlled node.According to the information of described conversion link, first node determines whether described conversion link meets preset requirement.When described conversion link meets preset requirement, described first node utilizes described conversion link to send described video to described main controlled node.Design of the present invention is described in detail below in conjunction with accompanying drawing.
