Problems solved by technology
[0004] However, as the screen content increases, the network bandwidth required for VR live broadcast also increases
In order to reduce the cost of network bandwidth, the existing VR live broadcast platform will reduce the video transmission bit rate, but this VR live broadcast may bring unclear and dizzy feeling to users, and the user experience will be greatly reduced

The invention provides a VR live broadcast method, device, system and equipment and a storage medium, and the method carries out the FOV panoramic slicing processing of a VR panoramic video stream pushed by a VR panoramic camera through an edge cloud platform, obtains a VR slice stream, reduces the actual use transmission bandwidth, reduces the network bandwidth cost, and enables a user terminal to carry out the live broadcast based on the VR slice stream. The 360-degree panoramic drawing is obtained, a good live broadcast effect is achieved, and the problems that in the prior art, the cost of network bandwidth is reduced, the transmission code rate of a VR live broadcast video is reduced, and unclearness and dizziness are brought to a user are solved. Besides, the edge cloud platform can also determine a main visual angle of a user corresponding to the user terminal and adjust camera parameters of the VR panoramic camera according to the main visual angle, so that a three-dimensional live scene can be restored more truly, the user can better experience a 3D effect and immersion. The degree of freedom of watching the live video by the user and the fluency of direction switching are also improved.
Description
technical field [0001] The present application relates to the field of live video technology, and in particular to a method, device, system, device and storage medium for a virtual reality (Virtual Reality, VR) live broadcast. Background technique [0002] Live streaming is a recently emerging form of exchange. During the live broadcast, the anchor holds the anchor device to collect images, and transmits the collected images to multiple viewer devices synchronously through the network in real time, so that many viewers can watch the images. At the same time, viewers can also input text, images, emoticons, gifts and other information on the viewing end device, and display it to the anchor end device and other viewing end devices through the network, and then interact with the anchor and other viewers online. [0003] VR live broadcasting combines virtual reality and live broadcasting, which is an emerging live broadcasting method. In terms of VR live broadcast, it has been ...
