Dynamic Range Conversion for HDR Video Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video game streaming configurations often fail to support the streaming of High-Dynamic-Range (HDR) video games, limiting the gaming experience for both players and viewers who wish to enjoy enhanced color representations and visual details.
Innovation Solution
The implementation of conversion components that allow for the conversion of HDR and Standard-Dynamic-Range (SDR) video inputs to HDR and SDR outputs, enabling HDR local video outputs for supported displays and allowing users to select HDR or SDR streaming options, while also providing resolution scaling and camera video conversion to ensure seamless streaming and local display compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If HDR video game streaming is implemented, then visual quality and color representation are improved, but device compatibility and system complexity worsen
Solution Approach 1:
A conversion component is introduced as an intermediary between the HDR video game source and the streaming system. This component converts HDR video content to SDR format for streaming transmission, while maintaining separate HDR output for local display. The intermediary handles the dynamic range conversion, allowing HDR gaming experience locally while enabling broad compatibility for remote viewers through SDR streaming.
Solution Approach 2:
The video output is segmented into separate streams: one HDR stream for local display and one SDR stream for remote streaming. This segmentation allows each stream to be optimized for its specific destination, with the conversion component creating distinct video feeds that can be independently processed and transmitted.
2Adaptability or versatility
If HDR to SDR conversion is implemented for streaming, then viewer compatibility is improved, but visual quality and color depth deteriorate
Solution Approach 1:
Different quality levels are provided for different viewing contexts: HDR quality for local players with capable displays, and SDR quality for remote viewers. The conversion component enables each viewer to receive video content appropriate to their display capabilities, with local players experiencing full HDR quality while remote viewers receive optimized SDR streams.
3Adaptability or versatility
If dynamic range conversion components are added, then streaming flexibility is improved, but device complexity and processing requirements worsen
Solution Approach 1:
The conversion component is designed to handle multiple functions: HDR to SDR conversion, video stream splitting, and output routing to different destinations. This multi-functional approach consolidates what could be multiple separate devices into a single universal component that manages both local HDR display and remote SDR streaming simultaneously.

AI summary
Conversion components may receive game video rendered in high-dynamic-range (HDR) and standard-dynamic-range (SDR) camera video of a game player. The conversion components may provide local video output to a local display and remote video output for network transmission to remote viewers. The SDR camera video may be converted to HDR and provided with HDR game video in the local video output. For HDR network transmission, the HDR game video and converted HDR camera video may be included in the remote video output. For SDR network transmission, the HDR game video may be converted to SDR and provided with the SDR camera video in the remote video output. The game video, camera video and other video feeds may have respective portals in the local and remote video outputs. The local and remote video outputs may have respective visual portal arrangements that may be at least partially different from one another.
