Remote Control Dynamic Shortcut Key Mapping for Rapid Channel Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices for digital display devices lack an efficient method for quickly and easily changing channels, particularly for frequently used channels, as they require users to input channel numbers or navigate through multiple menus, which can be cumbersome.
Innovation Solution
A channel change method using shortcut keys is introduced, where a mode change button on the remote control device switches numeric keys to shortcut keys, allowing users to set and use frequently used functions directly, without adding new buttons, by displaying application icons on the remote control device keys and enabling rapid channel changes through these shortcuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control device uses a traditional numeric key structure for channel selection, then the device structure remains simple, but the ease of operation deteriorates because users cannot quickly access frequently used channels
Solution Approach 1:
The remote control device dynamically changes the function of numeric keys based on the pressed order. The first pressed numeric key becomes a shortcut key for frequently used channels, allowing the device to adapt to user needs without adding physical buttons. This dynamic reassignment resolves the contradiction by improving ease of operation while maintaining simple device structure.
Solution Approach 2:
The patent changes the functional parameter of numeric keys from static to dynamic. By changing the mode from normal numeric input to shortcut key mode through a mode switch button, the same physical keys serve different functions, improving operational efficiency without increasing device complexity.
2Ease of operation
If additional buttons are added to the remote control for frequently used functions, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The numeric keys serve multiple functions: normal channel selection and shortcut key functions. By making the keys universal, the patent provides quick access to frequently used channels without adding new buttons, thus improving ease of operation while avoiding increased device complexity.
Solution Approach 2:
The system allows users to create their own shortcut keys by pressing numeric keys in a specific sequence, enabling the remote control to adapt to individual user needs without requiring pre-configured buttons or professional setup.
3Productivity
If the remote control device requires multiple menu navigation steps for function selection, then the device structure remains simple, but the loss of time increases
Solution Approach 1:
The patent enables preliminary setup of shortcut keys by pressing numeric keys in a specific sequence during a setup mode. This preliminary action stores frequently used channel information, allowing rapid channel changes without time-consuming menu navigation during actual use.
Solution Approach 2:
The shortcut key function allows users to skip the normal multi-step channel selection process by directly pressing a single numeric key that has been assigned as a shortcut, dramatically reducing the time required for channel changes.

AI summary
A display device including a display configured to display a received broadcast; a user input interface configured to receive a signal from a remote control device; and a controller configured to: when a function key setup mode entry signal is received from the remote control device, display a plurality of keys of the remote control device on the display, the plurality of keys respectively including images of numeric keys for inputting a desired number, display a mapped application icon on the image of a key to which an application is mapped among the plurality of keys, in response to a first preset input on the image of the key to which the application is mapped, input the desired number, and in response to a second preset input on the image of the key to which the application is mapped, stop the broadcast and execute the application.
