Display Device Thumbnail Search for Video Frame Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices rely on character information for content retrieval, requiring users to directly view and hear video and audio content to find specific video frames, limiting efficient search and retrieval capabilities, especially with the transition to digital broadcasting which offers more complex and diverse content services.
Innovation Solution
A display device and method that enables users to search for video frames and audio content based on character appearances without directly viewing them, using a content information database that indexes and stores spatial and temporal information, allowing for thumbnail-based selection and editing across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If content retrieval is based only on character information, then the device complexity is reduced, but the measurement precision of content search deteriorates
Solution Approach 1:
The patent segments content information into multiple dimensions: character information, spatial information (position, size, shape), and temporal information (time, duration). This segmentation allows the system to search for video frames based on specific attributes without requiring users to view the entire content, thereby improving search accuracy while maintaining manageable system complexity through organized information structure.
2Measurement precision
If users directly view and hear reproduced video and audio content to retrieve desired content, then the measurement precision of content identification is improved, but the loss of time increases
Solution Approach 1:
The patent implements preliminary action by pre-extracting and storing key information from video content during the content reproduction process. Character information, spatial information, and temporal information are captured and stored in advance, creating an index that enables rapid searching without requiring users to watch or listen to the entire video content, thus significantly reducing retrieval time while maintaining accurate content identification.
3Adaptability or versatility
If content is stored in another device, then the adaptability of the system is improved, but the loss of information increases due to device-specific retrieval limitations
Solution Approach 1:
The patent implements universality by designing a standardized information structure that can be stored and retrieved across different devices. The content information database stores character information, spatial information, and temporal information in a device-agnostic format, allowing the display device to search and retrieve specific video frames from content stored in other devices without losing retrieval information completeness, thereby enabling cross-device content access.

AI summary
A display device and a method for providing content using the display device are disclosed. A controller receives a search term and searches for at least one content including a video frame associated with the received search term. A display displays a list of the searched content.
