Display Device Automatic UIBC Trigger for Mirroring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital TV services, such as IPTV and smart TV, face challenges in automatically determining user intentions for controlling mobile terminals during mirroring and setting up the User Input Back Channel (UIBC) function without a complex process.
Innovation Solution
A display device equipped with a wireless communication interface and a controller that detects user input signals and transmits a UIBC trigger to the mobile terminal, allowing for automatic determination of user intentions and seamless execution of the UIBC function during mirroring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic determination of user intention is implemented during mirroring, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The display device automatically determines user intention to control the mobile terminal without requiring manual configuration or complex setup procedures. The system self-configures the UIBC function by detecting user input signals and automatically transmitting UIBC triggers, eliminating the need for users to manually navigate through complex setup processes while maintaining controlled system behavior.
2Ease of operation
If UIBC function setup is simplified, then ease of operation is improved, but reliability may deteriorate
Solution Approach 1:
The system establishes a feedback mechanism where the display device receives user input signals during mirroring operation, determines whether these signals indicate user intention to control the mobile terminal, and automatically transmits corresponding UIBC triggers. This feedback loop ensures reliable activation of the UIBC function based on actual user behavior while maintaining simple operation through automatic detection and response.
