Problems solved by technology

[0002] In the combined distributed large-scale audio and video service system, the network structure between the central nodes of the system includes mesh and tree, and the bandwidth of the network lines between each node and other central nodes is different, and different routing paths are available for data transmission. The actual network media stream transmission environment of the entire audio and video service system is very complicated due to the different bandwidths. When performing media stream data communication, the quality of multi-channel audio and video transmission is difficult to guarantee
During the peak period of system use, when audio and video transmission tasks are performed between any two nodes, the complex network transmission environment between nodes will affect the quality of audio and video transmission, and problems such as audio and video freezes and relatively large delays will occur.
However, due to the current network structure of the user system, the network bandwidth cannot meet the media service requirements between the central nodes in the system. However, increasing the network bandwidth of the entire system is too costly and time-consuming, which is not conducive to the development of user functions and services. Therefore, it is necessary to propose new way to solve this problem

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Such as Figure 1~2 The audio and video service system nodes shown in the diagram include nodes on the entire network and common central nodes. Each node is deployed in a region, so the central nodes are distributed in different regions. Therefore, when better business services are required between central nodes, it is necessary to establish a dedicated line between the two to transmit the media stream required by the business. Among them, the equipmen...

Abstract

The invention provides a method for guaranteeing smoothness of a media stream in a complex network structure. A straight through high bandwidth physical network line is built between two center nodes having frequent business contact of the system, so as to transmit audio video data between nodes guaranteeing the task, and guarantee the audio video transmission quality. When the nodes need better business services, a special line needs to be built between every two nodes to transmit the media stream required by the business, so that the problem that low network bandwidth environment cannot meet the business requirement is solved.

Description

technical field [0001] The invention belongs to the field of audio and video communication, and in particular relates to a method for ensuring smooth media flow in a complex network structure. Background technique [0002] In the combined distributed large-scale audio and video service system, the network structure between the central nodes of the system includes mesh and tree, and the bandwidth of the network lines between each node and other central nodes is different, and different routing paths are available for data transmission. The different bandwidths make the actual network media streaming environment of the entire audio and video service system very complex. When performing media streaming data communication, the quality of multi-channel audio and video transmission is difficult to guarantee. During the peak period of system use, when audio and video transmission tasks are performed between any two nodes, the complex network transmission environment between nodes w...
