Internet TV Module HDMI CEC Input Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy TVs with native user interfaces struggle to seamlessly integrate and navigate non-native user interfaces, preventing users from utilizing remote controls effectively due to the TV's lack of knowledge about non-native UI commands.
Innovation Solution
The implementation of HDMI and CEC links allows for seamless application launching and input event sharing between an Internet TV module and a TV, enabling unified user experiences without requiring porting of applications to different platforms, using HDMI input switching and IP connections to manage remote control inputs and switch between native and non-native UIs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a TV presents a non-native UI to allow access to application-based interfaces, then the viewer's range of choices and familiarity with the interface is improved, but the TV remote control cannot respond to commands because the TV has no knowledge of the non-native UI structure
Solution Approach 1:
The patent introduces an intermediary layer that translates remote control commands intended for a native UI into appropriate commands for the non-native UI. This mediator component enables the TV remote to effectively control applications running on non-native platforms without requiring the TV to have direct knowledge of the foreign UI structure, thus resolving the contradiction between interface versatility and operational ease
2Adaptability or versatility
If applications are ported to multiple platforms to ensure compatibility, then the user can access applications on different devices, but the complexity of maintaining and updating applications across platforms increases
Solution Approach 1:
The patent employs a copying approach where the UI presentation layer is replicated across different platforms while the core application logic remains unchanged. Instead of porting entire applications to multiple platforms, the system copies the necessary UI adaptation layer, allowing the same application to run on different platforms with minimal modification, thus reducing maintenance complexity while maintaining compatibility
3Ease of operation
If the TV automatically switches HDMI input to the module when an application is launched, then the user experience is seamless and unified, but the system must manage complex input switching and coordination between devices
Solution Approach 1:
The patent merges the control functions of multiple devices into a unified system. The TV and the external module are combined into a coordinated system where the TV handles display and basic control, while the module handles application execution. This merging allows automatic HDMI switching and seamless coordination without requiring complex manual configuration, achieving user experience continuity while distributing system complexity across components
Data Source
AI summary
A display device receive icon or application information from an audio visual application module (AVAM) and presents, on the native UI of the display, a selectable AVAM icon according to the information from the AVAM. The AVAM icon is associated with an application on the AVAM. Display input is automatically switched to the AVAM responsive to selection of the icon from the native UI using the display RC, at which point a non-native UI received from AVAM is presented for navigation using the display RC. Input commands are relayed to the AVAM.
