Method and system for interactive graphics streaming

Abstract

The present invention relates to a method of streaming interactive computer graphics from a server to a client device. The method includes the steps of: intercepting graphics instructions transmitted from an application destined for a graphical processing unit (GPU) at the server; processing the graphics instructions to generate graphics data at the server; generating index information for, at least, some of the graphics data at the server; transmitting the index information in place of the graphics data to a client device; extracting corresponding graphics data stored at the client device utilizing the index information; and rendering computer graphics at a graphical processing unit (GPU) at the client device using the corresponding graphics data. A system for streaming interactive computer graphics is also disclosed.

Description

technical field [0001] The present invention is in the field of interactive graphics streaming. More particularly, but not exclusively, the invention relates to interactive graphics streaming from an application on a server for display by a GPU on a remote client. Background technique [0002] In the field of interactive graphics applications, such as computer games, users typically download or obtain these applications through physical media and execute them locally on their devices. [0003] However, some providers of interactive graphics applications desire the flexibility and control of executing the graphics application at the server and streaming the rendered graphics from the application to the user across the network for display on the user device. [0004] The current state of the art in this form of streaming graphical content is to execute the application on a specialized server that provides a CPU, memory, backing memory, and a graphics processing unit (GPU) wit...

This increases server load and system latency

[0008] Fourth, tens of thousands of consumer devices (e.g., tablets, mobile devices, and smart TVs) increasingly contain powerful GPUs that are far away when all application graphics processing occurs on the server. underutilized resource

Furthermore, the MPEG-4 standard will result in the potential retransmission of graphics data from the server to the client for each new stream, resulting in an inefficient use of bandwidth between the server and client
