Problems solved by technology

At present, the production of live broadcast content is mainly completed locally at the live broadcast collection end. The collection end is deployed at the live broadcast site. Usually, a VR camera and a local server (for splicing, encoding, streaming, and broadcast guidance) need to be configured. The content generates a complete video stream, and then selects the video stream of a certain camera position through the broadcasting system, and injects it into the VR live broadcast platform through the network. This technical solution increases the hardware cost of the live broadcast acquisition terminal.
In addition, most of the existing live broadcast systems are centralized server systems, which are the key to the flow of live broadcast traffic, so they have high security requirements
The advantage of a centralized system lies in its high real-time performance and low latency, but at the same time, there are inherent defects in a centralized system, such as technical problems such as vulnerability to attacks and high cost of server clusters

Embodiment 1

[0036] Such as figure 2 As shown, a live broadcast collection method is suitable for a live broadcast collection terminal. The live broadcast collection terminal collects the first live broadcast content and performs preprocessing to form the second live broadcast content, which is sent to the first node or the second node through the 5G network communication protocol; wherein, The consensus algorithm formed by the P2P network architecture of the first node located in the cloud is in the main chain of POW; the consensus algorithm formed by the second node located in the P2P network architecture of the cloud is in the branch chain of POS or DPOS; between the main chains , between branch chains, and between the main chain and branch chains through API gateway protocol cross-chain communication.

[0037] As one of the optional implementations of this embodiment, the live broadcast collection terminal collects the first live broadcast content and performs preprocessing to form th...

Embodiment 2

[0042] Such as image 3 As shown, a live broadcast content processing method, according to a live broadcast collection method described in Embodiment 1, is suitable for the second node located on the branch chain to receive the second live broadcast content sent by the live broadcast collection terminal through the 5G network communication protocol , decapsulate and decode the second live content to restore the first live content; perform video splicing, encoding and streaming of the first live content to form the first content; the first content is combined with the AES encryption algorithm and the hash algorithm Encrypted into a second data packet, the second node creates the second data packet into a second transaction; broadcasts and verifies the second transaction through IoT edge computing and 5G network communication protocols, and the second transaction after verification is packaged into The second block is consensused on the branch chain through the POS or DPOS conse...

Embodiment 3

[0052] Such as Figure 4 As shown, a live broadcast content processing method, a live broadcast acquisition method according to Embodiment 1, and a live broadcast content processing method according to any technical solution of Embodiment 2 are applicable to the first live broadcast content located on the main chain One node receives the second live broadcast content sent by the live broadcast acquisition terminal through the 5G network communication protocol, decapsulates and decodes the second live broadcast content, and restores the first live broadcast content; performs video splicing, encoding and streaming of the first live broadcast content Form the first content; the first content is encrypted into the first data packet by the AES encryption algorithm, and the first node creates the first data packet into the first transaction; receives the second transaction or the second block sent by the second node , broadcast and verify the first transaction, second transaction or...

Abstract

The invention discloses a live broadcast method, equipment and storage medium, and relates to the technical field of data transmission. The second node; wherein, the first node is located in the main chain of POW formed by the consensus algorithm of the P2P network structure in the cloud; the second node is located in the branch chain of POS or DPOS formed by the consensus algorithm formed by the P2P network structure of the cloud; Cross-chain communication is performed between the main chains, between the fork chains, and between the main chain and the fork chains through the API gateway protocol. Aiming at the security technical problems existing in the centralized live broadcast system in the existing technology, it applies the distributed cloud system of the blockchain network in the live broadcast field. High concurrency.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a live broadcast method, device and storage medium. Background technique [0002] Live broadcasting is a way of live and instant broadcasting of program content such as voice, text, pictures or video through broadcast media such as radio stations, TV stations, and network platforms. At present, the production of live broadcast content is mainly completed locally at the live broadcast collection end. The collection end is deployed at the live broadcast site. Usually, VR cameras and local servers (for splicing, encoding, streaming, and broadcast guidance) need to be configured. The content generates a complete video stream, and then selects the video stream of a certain camera position through the broadcasting system, and injects it into the VR live broadcast platform through the network. This technical solution increases the hardware cost of the live broadcast ac...
