Thumbnail Update Mechanism for Digital Broadcasting Channel Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of digital broadcasting channels increases, users face difficulty in selecting channels due to the time-consuming process of navigating through multiple options, especially when trying to find preferred or new programs.
Innovation Solution
An image display apparatus and operation method that generate and display thumbnail images for each channel, allowing for different update periods for each thumbnail, enabling users to easily identify and select channels by prioritizing updates for preferred or new programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of broadcast channels increases to meet various user demands, then the variety of programs available to users is improved, but the time required for users to select a channel increases
Solution Approach 1:
The patent creates thumbnail image copies of the broadcast content for each channel. Instead of requiring users to navigate through multiple channel options, the system generates visual thumbnails that represent each channel's current program, allowing users to quickly identify and select desired content through visual inspection rather than sequential channel surfing.
Solution Approach 2:
The patent employs visual characteristics including color and image content in thumbnail generation. Different channels are represented by distinct visual appearances through their program thumbnails, and the system can highlight or change visual properties of thumbnails based on user preferences, program types, or selection state, enabling rapid visual discrimination between channels.
2Device complexity
If all thumbnail images are updated at the same rate, then the system complexity is reduced, but user-preferred channels may not be highlighted effectively
Solution Approach 1:
The patent implements differential update strategies where different thumbnail images are updated at different rates based on local characteristics. User-preferred channels, newly added channels, or channels with live sports events can be configured to update more frequently, while other channels use standard update intervals. This allows the system to highlight important channels without requiring complete system-wide redesign.
Solution Approach 2:
The thumbnail update system is dynamic and adaptive. Update frequencies can change based on user behavior patterns, program types, and channel importance. The system can automatically adjust update rates or allow users to customize them, making the channel identification process more efficient as user preferences evolve over time.

AI summary
A method for operating an image display apparatus includes generating a plurality of thumbnail images based on an input signal, displaying a thumbnail list including at least one of the plurality of the generated thumbnail images, and updating at least one of the thumbnail images included in the thumbnail list. An update period of a thumbnail image is different from an update period of another thumbnail image in the thumbnail list.
