Embodiment 1

[0038] The present invention utilizes the NAT traversal technology to allow the broadcasting equipment to establish a peer-to-peer interconnection (Peer-to-Peer, P2P for short), and builds the broadcasting equipment in the system into a P2P distribution network in a tree structure. The distribution network organized in a tree structure is called a P2P distribution tree, and the broadcasting devices are called nodes. The root node of the P2P distribution tree obtains the live stream or file from the server, and other nodes obtain the live stream or file from the parent node through the P2P connection between nodes.

[0039] Three nodes in the distribution tree form a node group, and a node group connects 12 child nodes. Such as figure 1 ( figure 2 ), node 1, node 2, and node 3 are root nodes, and nodes 4 to 15 establish P2P connections with node 1, node 2, and node 3 respectively.

[0040] The distribution tree can be composed of more than two levels of hierarchy, such as i...

Embodiment 2

[0051] In this embodiment, the broadcast device has NAT type detection and bandwidth detection capabilities, and can report to the server. The system establishes a distribution tree according to the NAT type of nodes and network bandwidth data to realize P2P networking.

[0052] The broadcasting device connects 3 parent nodes and 12 child nodes in the distribution tree. The server can send a message informing the node to connect to the specified parent node.

[0053] The broadcast device establishes a P2P connection with the parent node through NAT penetration technology. The broadcasting equipment utilizes the P2P network to realize the distribution of live streaming and files, reducing the number of broadcasting equipment that directly obtains data from the server, and reducing the bandwidth pressure and traffic cost of the server.

[0054] The broadcast device preferentially uses the P2P connection to obtain live streams or files from the parent node, and can switch to ob...

Embodiment 3

[0056] A P2P networking and live streaming and file distribution method for a digital broadcasting system, deploying a digital broadcasting system, including forwarding streaming media servers for live streaming, broadcasting equipment and clients; using NAT penetration technology to allow broadcasting equipment to establish point-to-point (P2P) interconnection, constructing a P2P distribution network (distribution tree) in the broadcasting equipment in the system according to a tree structure, and distributing live streams and files through the distribution network.

[0057] Preferably, the P2P distribution network is a hierarchical structure of two or more layers, including a server layer, a root node layer, and a child node layer, wherein the root node in the root node layer obtains a live stream from a server in the server layer or Files, other sub-node layer nodes obtain live streams or files from the parent node through the P2P connection between nodes.

[0058] Preferab...

Abstract

The invention discloses a P2P networking and live stream and file distribution method for a digital broadcasting system, and the method comprises the steps: deploying a digital broadcasting system, and the digital broadcasting system comprising a streaming media forwarding server for live streams, broadcasting equipment, and a client; and establishing point-to-point interconnection of broadcast equipment by utilizing an NAT penetration technology, establishing a P2P distribution network by the broadcast equipment in the system according to a tree structure, and distributing live streams and files through the distribution network. The P2P distribution network is of a two-layer or more than two-layer hierarchical structure. The P2P distribution network comprises a server layer, a root node layer and a child node layer. A root node in the root node layer obtains live streams or files from a server in the server layer, and nodes of other child node layers obtain the live streams or files from father nodes through P2P connection between the nodes. The broadcast equipment realizes distribution of live streams and files by using a P2P network, the number of the broadcast equipment for directly obtaining data from a server is reduced, and the machine room bandwidth requirement of the internet-based large-scale broadcast system is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of data services in the communication field, in particular to a P2P networking of a digital broadcasting system, a method, a device and a storage medium for distributing live streams and files. Background technique [0002] The live broadcast in the digital broadcasting system refers to a kind of real-time audio broadcasting. The audio collection equipment collects real-time audio and transmits it to various broadcasting equipment through the network, and the broadcasting equipment performs amplifying and broadcasting. [0003] File distribution in the digital broadcasting system means that the system transmits the audio files on the server side to various broadcasting equipment through the network, and the broadcasting equipment plays the audio files at an appropriate moment. [0004] At present, when a general digital broadcasting system performs live broadcast and file distribution, the bandwidth ...
