Screen Navigation History Management for Set-Top Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in accessing specific services or screens on TV set-top boxes due to the lack of efficient navigation history management, requiring multiple remote control manipulations to navigate through menus and services.
Innovation Solution
A method and apparatus for saving and managing screen navigation history, including an input unit, communication unit, memory, display unit, and control unit, which create a screen navigation history list with shortcut keys and thumbnail images, allowing direct access to previously visited screens and services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a user navigates through multiple menus to access a specific service, then the service can be accessed, but the user has to manipulate several remote controls and spend excessive time
Solution Approach 1:
The system performs preliminary action by automatically recording and storing the navigation path (sequence of menus and screens) as the user navigates through the interface. This recorded history is then made available for quick retrieval, eliminating the need to repeat the same navigation steps. When a user selects a service, the system automatically recalls the stored navigation path and executes it, allowing direct access to the desired service without manual navigation through multiple menus.
2Adaptability or versatility
If only a simple 'return to previous menu' function is provided, then the system structure remains simple, but the user cannot easily access various services used previously
Solution Approach 1:
The navigation history is segmented into discrete path records, where each record represents a complete navigation sequence from a starting point to a target service. This segmentation allows the system to store multiple independent service access paths without creating a complex interconnected structure. Each segmented path can be independently retrieved and executed, providing versatile service access while maintaining manageable system complexity through modular organization of navigation data.
