Channel Scroll UI for Fast TV Channel Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face difficulties in quickly switching between numerous channels, as current methods such as channel up/down buttons or memorizing channel numbers become cumbersome when dealing with a large number of channels.
Innovation Solution
A display apparatus and method that generate a channel scroll user interface (UI) upon a long press of a channel button, allowing users to scroll through and select channels efficiently, with the processor identifying the image providing source and controlling the display to show a list of channels, including a current channel indicator, and switching to the selected channel upon user input or a predefined period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If channel up or down key is pressed once, then current channel is sequentially changed to adjacent channels, but channel switching becomes time-consuming when many channels are stored
Solution Approach 1:
The patent segments the channel list into multiple groups (e.g., by category, frequency band, or service type) and displays them in a scrollable interface. Users can navigate through grouped channels rather than sequentially traversing all channels one by one, significantly reducing the time required to find and switch to desired channels.
Solution Approach 2:
The patent introduces a new dimension for channel navigation by displaying channels in a scrollable list interface with multiple visual dimensions (scroll position, selection state, group categorization). This allows users to quickly locate channels by scrolling to specific positions or groups rather than incrementally pressing channel up/down keys, transforming linear sequential navigation into rapid multi-dimensional access.
2Loss of time
If channel number is directly input using numeric key, then fast channel switch is achieved, but channel number must be memorized
Solution Approach 1:
The patent introduces an intermediary channel scroll UI that acts as a mediator between the user and the channel switching function. Instead of requiring direct numeric input, the UI presents a scrollable list of channel names and identifiers that users can navigate visually. This intermediary interface eliminates the need to memorize channel numbers while still enabling fast channel switching through efficient scrolling and selection mechanisms.
Solution Approach 2:
The patent creates a visual copy or representation of the channel list in the scrollable UI, displaying channel identifiers, names, and metadata. Users can interact with this visual copy to select channels without needing to recall or input the actual channel numbers, thereby maintaining fast switching capability while removing the memorization burden.
3Productivity
If channel scroll UI is displayed with plurality of channel items, then channel navigation becomes efficient, but device complexity increases
Solution Approach 1:
The patent implements a universal channel scroll UI framework that can handle multiple channel sources (broadcasting stations, external apparatuses, different service types) through a single standardized interface. The UI generation logic is designed to work with various channel information formats and sources, reducing the need for separate handling mechanisms for each case and thereby managing complexity while maintaining high navigation efficiency.
Solution Approach 2:
The patent employs parameter-based channel information structures that can be dynamically adjusted based on the image providing source (TV, external apparatus, broadcasting signal). By changing parameters such as channel grouping criteria, display format, and scroll behavior based on the source type, the system achieves efficient channel navigation across different scenarios without requiring fundamentally different UI implementations for each case.
Data Source
AI summary
A display apparatus and a method of operating the same are provided. The display apparatus includes a display; a memory; and a processor configured to execute at least one instruction stored in the memory so as to: receive a channel control input; identify an image providing source of the display apparatus in response to recognizing the channel control input as a pre-designated input; generate a channel scroll user interface (UI) based on channel information corresponding to the image providing source of the display apparatus; and control the display to display the generated channel scroll UI. The channel scroll UI includes a plurality of channel items included in the channel information corresponding to the image providing source, and a current channel indicator indicating a current channel item from among the plurality of channel items, the current channel item corresponding to content currently displayed on the display apparatus.
