Adaptive Screen Configuration for Multimedia Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia transmission methods do not consider varying transmission bands and error rates, leading to deteriorated video display and incomplete content rendering on reception terminals with different screen sizes and capabilities.
Innovation Solution
Transmitting multiple screen configuration options based on transmission band and screen size, allowing reception terminals to select and display content using the most suitable configuration, reducing content loss and ensuring optimal display on varying devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a single screen configuration information is transmitted for all terminals, then the transmission data amount is reduced, but the display quality deteriorates on terminals with different screen sizes and capabilities
Solution Approach 1:
The screen configuration information is segmented into multiple versions corresponding to different terminal types (mobile phones, PDAs, notebook PCs, etc.). Each version contains display parameters optimized for specific screen sizes and capabilities. The transmission system divides the configuration data into targeted segments rather than sending a single universal configuration, thereby reducing overall transmission overhead while ensuring each terminal receives only the relevant configuration version.
2Manufacturing precision
If multiple screen configuration options are transmitted for different terminals, then the display quality is improved, but the transmission data amount increases
Solution Approach 1:
Different screen configuration versions are created with local quality optimizations tailored to specific terminal characteristics. Each configuration version contains display parameters (such as region definitions, content layout, resolution settings) that are locally optimized for particular screen sizes and terminal capabilities. This allows high display quality for each terminal type without transmitting all possible configuration variations to every terminal.
Solution Approach 2:
The screen configuration information uses parameter changes to adapt to different terminals. Key parameters such as display region coordinates, content scaling factors, and resolution settings are varied across different configuration versions. By changing these parameters based on terminal type, the system achieves optimal display quality for each device category while maintaining a manageable data structure that can be efficiently transmitted.
3Manufacturing precision
If screen configuration information is optimized for large screens, then the display quality is improved on large screens, but the content cannot be fully displayed on small screens
Solution Approach 1:
The screen configuration system is made dynamic by providing multiple configuration versions that can be selected based on terminal screen size. Instead of a static single configuration, the system dynamically adapts to the receiving terminal's capabilities. Mobile phones receive compact configurations optimized for small displays, while notebook PCs receive configurations optimized for larger screens, ensuring both high display quality and full content visibility for each device type.
