Server-Side Video Rendering for Online Gaming Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Online applications, such as online gaming systems, experience noticeable delays due to network conditions and the complexity of rendering video images on servers, and existing solutions that render images on user devices require high-performance graphics, increasing costs.
Innovation Solution
Implementing server-side rendering where the server identifies future user actions and renders video images representing these actions, limiting them to the most likely outcomes, and transmitting these images to user devices for display, with optional compression based on network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video images are rendered on the server, then centralized control and consistency are improved, but network delay and rendering latency increase
Solution Approach 1:
The server pre-renders video images for multiple possible future user actions before the user actually performs them. When a user is in a particular state, the server identifies possible future actions and renders corresponding video images in advance, storing them for quick retrieval. This eliminates real-time rendering delay while maintaining centralized control.
2Speed
If video images are rendered on the user device, then response time is improved, but device cost and graphics performance requirements increase
Solution Approach 1:
The rendering function is extracted from the user device and transferred to the server. The user device only needs to send user actions to the server and display received video images, eliminating the need for high-performance local graphics processing while maintaining fast response times.
3Adaptability or versatility
If all possible future user actions are rendered, then completeness of content is improved, but data transmission volume and processing complexity increase
Solution Approach 1:
Instead of rendering all possible future user actions, the server renders only a subset of video images corresponding to identified possible future actions. This partial rendering approach provides sufficient content adaptability while significantly reducing data transmission volume and processing complexity.

AI summary
A solution for server-side rendering includes, at a server configured to store a video images representing states of users in a computer application, identifying future user actions based at least in part on a state of a user in the computer application. The solution also includes, responsive to the identifying, rendering video images for sending to a user device associated with the user. At the user device, a state of the user in a computer application is sent to the server. Responsive to the sending, video images are stored, each of the video images representing a future state of the user after the user performs a future action. Responsive to a user action, one of the video images is selected for display on a user display of the user device. According to one aspect, the future user actions identified by the server are limited to less than a possible number of user actions for users having the state.
