Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless connections between display devices and peripherals can be affected by interference, leading to deteriorated network quality, which impacts the transmission of data.
Innovation Solution
An electronic device adjusts the resolution or frame rate of image data based on network quality and content type, using processors to identify content type and network conditions, and applies downscaling or frame skip to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image data is transmitted at high resolution and high frame rate, then display quality is improved, but data transmission stability deteriorates due to network interference
Solution Approach 1:
The patent applies dynamic adaptation by adjusting image data parameters (resolution and frame rate) based on real-time network quality assessment. The system dynamically switches between high quality mode (good network) and reduced quality mode (poor network), making the transmission adaptable to changing network conditions rather than static
Solution Approach 2:
The patent changes key parameters of image data (resolution and frame rate) according to network conditions. When network quality deteriorates, the system reduces resolution and/or frame rate to maintain stable transmission, while restoring high parameters when network conditions improve
2Reliability
If resolution of image data is reduced, then data transmission stability is improved, but display quality deteriorates
Solution Approach 1:
The system dynamically adjusts resolution based on network conditions, switching between high resolution (good network) and reduced resolution (poor network). This dynamic adaptation ensures that resolution reduction is temporary and conditional, maintaining display quality when possible while ensuring stability when needed
3Reliability
If frame rate of image data is reduced, then data transmission stability is improved, but display quality deteriorates
Solution Approach 1:
The system dynamically adjusts frame rate based on network conditions, reducing frame rate when network quality is poor and restoring it when network conditions improve. This dynamic adjustment ensures minimal impact on display quality while maintaining transmission stability
4Reliability
If network quality is poor, then data transmission stability should be prioritized, but this causes delay in content transmission
Solution Approach 1:
The system dynamically adjusts image data parameters in response to network conditions, reducing resolution and/or frame rate when network quality deteriorates to maintain stable transmission and minimize delays, while restoring high parameters when network conditions improve
