Content Sharing Device Selective Transcoding HDR10+ Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices that do not support HDR10+ technology struggle to share high-quality content with devices that do, resulting in low-quality playback due to differences in dynamic range standards.
Innovation Solution
A content sharing method and device that receive a target video, determine its standard, and selectively transcode it into HDR10 or HDR10+ standards based on sharing type, either in real-time slice mode or full transcoding, to improve image quality and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If selective transcoding is performed to improve content sharing quality, then image quality is improved, but transcoding overhead and processing time increase
Solution Approach 1:
The system performs preliminary detection of the target receiver's HDR10+ support status before initiating transcoding. By pre-identifying which devices require HDR10+ conversion and which don't, the system avoids unnecessary transcoding operations, thereby reducing processing time and overhead while maintaining high image quality for those who need it
Solution Approach 2:
The system dynamically changes video encoding parameters (specifically HDR10+ metadata and color space parameters) based on the receiver's capabilities. For HDR10+ capable devices, full HDR10+ parameters are applied; for non-capable devices, standard HDR parameters are used. This selective parameter adjustment improves image quality where needed while minimizing unnecessary processing overhead
2Productivity
If real-time slice mode transcoding is used, then real-time sharing efficiency is maintained, but image quality may be compromised
Solution Approach 1:
The video stream is divided into slices that can be processed and transmitted independently in real-time. This segmentation allows the system to maintain real-time sharing efficiency by processing only necessary portions of the video stream, while still applying quality-preserving HDR10+ transcoding to the segmented data without requiring full-video reprocessing
Solution Approach 2:
The system dynamically adjusts the transcoding process based on real-time conditions, switching between full transcoding and slice-mode transcoding depending on the receiver's HDR10+ capability and the current sharing context. This dynamic approach ensures both real-time efficiency and image quality are maintained appropriately for each scenario
3Adaptability or versatility
If full transcoding to HDR10+ is performed, then compatibility with high-performance devices is improved, but processing complexity increases
Solution Approach 1:
The transmitting device automatically detects the receiver's HDR10+ capability and self-adjusts the transcoding parameters accordingly. This self-service mechanism eliminates the need for manual configuration or complex external control systems, reducing processing complexity while maintaining optimal compatibility with both HDR10+ capable and non-capable devices

AI summary
Disclosed is a content sharing method, an electronic device and a non-transitory computer-readable storage medium, wherein the content sharing method includes: receiving a target video, determining a type of video sharing based on the target video not being a High Dynamic Range 10+ (HDR10+) standard video, selectively transcoding the target video to a different standard video based on whether the determined type of video sharing is a real-time video sharing, and sending the transcoded target video to a target receiver.
