Solution Overview
Problem
Streaming high-quality multimedia content for cloud gaming is resource-intensive and often hindered by network latency, traffic congestion, and the need for reliable, high-speed internet connections.
Innovation Solution
A method of adaptive streaming that separates multimedia content into multiple components, each processed and prepared differently based on its features, allowing for optimized resource allocation and reduced latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-quality multimedia content is streamed to cloud gaming clients, then user experience quality is improved, but network latency and bandwidth requirements increase
Solution Approach 1:
The multimedia content is segmented into multiple components including geometry data, texture data, and animation data. Each component is processed and transmitted separately, allowing for optimized compression and prioritization of critical rendering elements, thereby reducing overall transmission latency while maintaining visual quality
Solution Approach 2:
Critical rendering components such as geometry and skeletal animation data are extracted and transmitted with higher priority and lower compression ratios, while less critical components like high-frequency texture details are compressed more aggressively. This selective extraction ensures that essential visual information reaches the client with minimal latency
2Quantity of substance
If data compression is applied to reduce bandwidth usage, then network efficiency is improved, but quality of multimedia content deteriorates
Solution Approach 1:
Different compression ratios and algorithms are applied to different components based on their visual importance and sensitivity to compression artifacts. Geometry data receives minimal compression to preserve spatial accuracy, while texture data uses perceptual compression that maintains visual quality at lower bitrates, achieving optimal bandwidth efficiency without noticeable quality loss
3Manufacturing precision
If complete multimedia content is transmitted to ensure quality, then user experience is improved, but processing resources at server and client increase
Solution Approach 1:
Geometry data, skeletal animation data, and low-frequency texture data are pre-computed and transmitted in advance during scene setup or previous frames. This preliminary transmission allows the client to begin rendering preparation early, reducing real-time processing requirements and energy consumption during critical playback periods

AI summary
The present disclosure describes a method and system for adaptively streaming multimedia content. Data relating to the multimedia content is separated into a plurality of components, each of the components corresponding to one or more features of the multimedia content. The plurality of components are prepared for transmission to a client device, wherein a different preparation is applied to each component depending on the one or more features of a respective component. The prepared components are transmitted from the server to the client device.
