Smart TV Key Control Policy Mapping for UI Adaptation

The patent segments the key processing system into multiple components: a universal key processing module that handles basic key reception, and UI-specific policy modules that define custom key mappings for different interfaces. This segmentation allows the system to maintain a simple core processing path while enabling specialized behavior through separate policy definitions, thus resolving the contradiction between low complexity and high adaptability.

The patent creates a universal key processing framework that can serve multiple UI types through a common interface. The key processing module is designed to work with any UI by loading appropriate policy configurations, making it multi-functional. This universal module handles the majority of key processing needs while allowing UI-specific customization through policies, achieving both simplicity and adaptability.

The patent extracts the complex key processing logic from individual UI layers and consolidates it into a separate, centralized key processing module. Each UI no longer needs its own embedded key handling code; instead, they reference shared policy configurations. This extraction reduces overall system complexity while maintaining UI-specific adaptability through the policy mechanism.

The patent introduces a key processing module as an intermediary between the remote control input and various UIs. This mediator receives all key inputs, consults the appropriate UI-specific policies, and generates the corresponding control instructions. By positioning this intermediary layer, the system achieves UI-specific adaptability without requiring each UI to implement its own complex key handling logic.
