Cloud VR video live broadcast system based on 5G and MEC

Abstract

The invention discloses a Cloud VR video live broadcast system based on 5G and MEC. A content layer comprises a VR video shooting system which is used for providing real-time VR video content for a platform layer. A platform layer comprises a VR live broadcast system used for real-time import, transcoding, slicing and outflow of a VR video in Cloud VR video live broadcast; A network layer is based on an operator 5G / 4G wireless network MEC system and is used for providing stable transmission for the Cloud VR video service and realizing data interaction between the platform layer and the terminal layer as well as between the platform layer and the content layer; and A terminal layer comprises a Cloud VR terminal and is used for realizing the functions of VR video content presentation, network access and user authentication, accessing the MEC system through the network layer and directly accessing the VR video stream in the cloud platform layer or the MEC system through the local shunting function. The system has the characteristics of large bandwidth, low time delay, reliable network transmission and difficult congestion of the Cloud VR video live broadcast.

Description

technical field [0001] The invention belongs to the field of network video technology, and specifically relates to a Cloud VR video live broadcast system based on 5G and MEC, which has large bandwidth, low delay, reliable network transmission and is not easy to be congested. Background technique [0002] The cloudization of virtual reality (Cloud Virtual Reality, hereinafter referred to as Cloud VR) is to introduce the concept and technology of cloud computing and cloud rendering into business applications such as VR video, and use the high-speed and stable network to integrate the display output and sound output of the cloud, etc. After encoding and compression, it is transmitted to the user's terminal equipment, so that business content such as VR video can be uploaded to the cloud and rendered to the cloud. [0003] Cloud VR requires data interaction between the terminal and the cloud based on the network. The characteristics of cloud-based virtual reality include cordles...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned problems in the prior art, the present invention proposes a Cloud VR video live broadcast system based on 5G and MEC, which is used to solve the problem that the network transmission mode in Cloud VR live video broadcast cannot meet the requirements of large bandwidth and low delay, and transmit multi-channel high-definition VR The video caused a sharp increase in the pressure on the operator's network and network congestion, and the problem that traditional VR video shooting cannot be remotely controlled from the first perspective to achieve all-round and multi-angle intelligent shooting
