Display Channel Scroll UI for Fast Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face difficulties in quickly switching between numerous channels, as methods like 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) based on channel information, allowing users to easily switch channels by moving a current channel indicator within the UI, either through a long press of a channel button or by obtaining channel information from a TV or external apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If channel up or down key is pressed to switch channels sequentially, then channel switching is simple to operate, but it takes long time to switch through many channels
Solution Approach 1:
The patent implements dynamic channel switching behavior based on press duration. A short press triggers sequential channel switching, while a long press (exceeding a predetermined time threshold) triggers direct channel number input mode. This dynamic response allows users to quickly switch to specific channels by holding the button and entering the channel number, rather than sequentially navigating through all channels.
Solution Approach 2:
The patent changes the operational parameter of the channel button from a simple toggle (short press) to a time-dependent control (long press with duration threshold). By introducing a time threshold parameter, the system distinguishes between different user intentions: brief presses for sequential switching and prolonged presses for direct channel number input, thereby resolving the contradiction between ease of operation and switching speed.
2Loss of time
If direct channel number input is used to switch channels quickly, then channel switching speed increases, but user must memorize channel numbers
Solution Approach 1:
The patent performs preliminary action by automatically displaying the channel number input interface when a long press is detected. Instead of requiring users to first memorize and then input channel numbers, the system proactively presents the numeric keypad and channel number fields, guiding users through the input process. This preliminary display action reduces the cognitive load and makes direct channel switching easier.
Solution Approach 2:
The patent introduces an intermediary interface (numeric keypad and channel number display) between the user's long press action and the channel switching function. This intermediary provides a visual guide and structured input method, making the direct channel switching process more user-friendly and less dependent on memorization.
3Ease of operation
If a channel list is displayed for selection, then users can visually select channels, but it increases device complexity and navigation time
Solution Approach 1:
The patent extracts the channel number input functionality from the main channel switching flow and activates it only through a specific long press gesture. Instead of always displaying a full channel list or requiring complex navigation, the system extracts and presents only the necessary channel number input interface when needed, reducing overall system complexity while maintaining ease of channel selection.

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.
