METHOD AND SYSTEM FOR GPU BASED VIRTUAL REALITY VIDEO STREAMING SERVER

Document Type and Number:

WIPO Patent Application WO/2017/142354

Kind Code:

A1

Abstract:

Provided are a system and a method for processing and streaming a virtual reality video using a graphic processing unit (GPU). A video server is configured to cause a processor to read source video data including a plurality of specific image frame data from a video data source, and to store the source video data in a first memory. In response to the first specific image frame data being stored in a first frame buffer of a second memory, the video server causes the GPU to transform the first specific image frame data into a first equirectangular image frame corresponding to a portion of a specific image represented by the first specific image frame data, to encode the converted first equirectangular image frame data, and to store the encoded first equirectangular image frame data in an encoded frame buffer of the second memory.
