Channel List Display With ATSC 3.0 Program Preview Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses, such as TVs, require users to manually switch through channels to find an interesting program, which is time-consuming and inefficient due to the lack of program information in the channel list.
Innovation Solution
The display apparatus displays channel information alongside a program preview image, obtained from a broadcast system like ATSC 3.0, allowing users to quickly identify interesting programs without switching channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the channel list displays only basic channel information without program preview images, then the device complexity is low, but the time required for users to find interesting programs increases significantly
Solution Approach 1:
The system performs preliminary action by obtaining and displaying program preview images and program information in advance within the channel list interface. This allows users to see what programs are currently playing on each channel before switching, eliminating the need to manually tune through channels to find interesting content. The preview images and program information are prepared and displayed proactively, resolving the technical contradiction by reducing time loss without significantly increasing device complexity.
2Productivity
If the channel list includes program preview images and program information, then user efficiency improves, but the device complexity and information processing requirements increase
Solution Approach 1:
The system uses an intermediary approach by introducing a channel list interface that acts as a mediator between the broadcast system and the user. This interface aggregates and displays program preview images and program information from multiple channels in one place, allowing users to make informed channel selections without directly interacting with each channel's full information stream. The intermediary channel list simplifies the information processing burden while maintaining high productivity.
3Loss of information
If the system displays detailed program information for all channels, then the loss of information is reduced, but the ease of operation decreases due to information overload
Solution Approach 1:
The system applies the extraction principle by selectively displaying only the most relevant program information and preview images in the channel list interface. Rather than showing all available information for every channel simultaneously, the system extracts and displays key elements such as current program titles, preview images, and essential program details. This reduces information overload and maintains ease of operation while preventing information loss by providing sufficient data for informed channel selection.

AI summary
Disclosed are a display apparatus and method. The display apparatus can include a display, a user input interface, a speaker and a remote control. The display apparatus can obtain channel information and a program preview image of a channel according to data stream received from a broadcast system, where the program preview image is used to show program information currently being played on the channel, and the broadcast system comprises ATSC 3.0 system; and in response to receiving a command for displaying a channel list, display the channel information and the program preview image of the channel in a channel list interface on the display.
