Title:
METHOD AND SYSTEM FOR VR IMAGE COMPRESSION AND TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2022/267256
Kind Code:
A1
Abstract:
The present disclosure provides a method and system for VR image compression and transmission, the method comprising: firstly, acquiring a video image to be sent by a server, and performing, according to a compression range, fixed-domain compression on the video image so as to form a first compressed video image, and then performing video encoding on the first compressed video image to form a transmission video image, then transmitting the transmission video image to a client, and performing video decoding on the transmission video image so as to restore the transmission video image as a second compressed video image, then decompressing the second compressed video image to form a display video image, that is, using D3D or OpenGL computation as a medium, and using an image shader program to compress image data within the compression range of an edge, thereby reducing the resolution of the overall image by compressing the resolution of the edge image, thereby reducing the volume of the image, improving transmission rate, and further improving the stability of VR live broadcasting and VR streaming.
