Dynamic Video Catalogue Entry Resizing for Content Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in efficiently browsing video content in video display systems, as existing methods require multiple interactions and fixed representations, making it time-consuming to determine if available video material meets their interests.
Innovation Solution
A video display apparatus that allows users to resize catalogue entries using a select-and-drag operation, dynamically increasing the number of representative images displayed, enabling users to quickly assess video content without opening additional screens, with images remaining constant in size and providing an intuitive, flexible interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple representative images are displayed to provide better content indication, then the information quality improves, but the interface complexity and interaction requirements increase
Solution Approach 1:
The catalogue entry size is made dynamically adjustable through user interaction. When the user hovers over or clicks a catalogue entry, it expands to display multiple representative images. This dynamic resizing allows the interface to adapt between a compact view (single image) and an expanded view (multiple images) based on user needs, resolving the contradiction between information quality and interface complexity.
Solution Approach 2:
The system changes the display parameter of catalogue entries from fixed size to variable size. By modifying the size parameter in response to user interaction, the system can display either a single representative image for quick browsing or multiple representative images for detailed inspection, thus balancing information quality with interface simplicity.
2Ease of operation
If fixed single representative image is displayed, then the interface simplicity is maintained, but the content representation accuracy deteriorates
Solution Approach 1:
The catalogue entry transitions from a static single-image display to a dynamic multi-image display upon user interaction. The entry expands to reveal multiple representative images when the user hovers or clicks, providing accurate content representation only when needed, thus maintaining interface simplicity during normal browsing while improving content accuracy on demand.
Solution Approach 2:
The system prepares multiple representative images in advance but keeps them hidden until user interaction triggers their display. This preliminary preparation allows the system to quickly expand the catalogue entry and show accurate content representation without requiring complex real-time processing, maintaining both interface simplicity and content accuracy.
3Loss of information
If multiple levels of detail are provided as in prior art, then the information completeness improves, but the number of interactions required increases
Solution Approach 1:
The patent merges the catalogue entry expansion function with the representative image display function into a single interaction. When the user hovers or clicks a catalogue entry, it simultaneously expands and displays multiple representative images, eliminating the need for separate interactions to access different levels of detail as required by prior art systems.
Solution Approach 2:
The system pre-loads and prepares multiple representative images for each video item in advance. When the user interacts with a catalogue entry, these pre-prepared images are immediately displayed without requiring additional loading steps or interactions, thus providing complete information while minimizing interaction time.

AI summary
A video display apparatus for displaying a catalogue of one or more candidate video items for replay, each video item being represented in the catalogue by a catalogue entry having at least one displayed representative image comprises a user control device operable to resize a displayed catalogue entry by a select-and-drag operation; and means responsive to a resizing of a catalogue entry to select a number of distinct representative images, for display in respect of that video item, so that the number displayed increases with increasing size of the catalogue entry while the display size of each representative image stays substantially constant with respect to changes in the catalogue entry size.
