Title:
ＧＰＵベースの仮想現実ビデオストリーミングサーバのための方法およびシステム
Document Type and Number:
Japanese Patent JP6663043
Kind Code:
B2
Abstract:
Provided are a system and a method for processing and streaming a virtual reality video using a graphics processing unit (GPU). A video server is configured to cause a processor to read, from a video data source, source video data including multiple spherical 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 spherical image frame data into a first equirectangular image frame corresponding to a portion of spherical image represented by the first spherical image frame data, to encode the converted first equirectangular image frame data, and store the encoded first equirectangular image frame data in an encoded frame buffer of the second memory.
