Digital Device Controller Keyword Extraction for Content Information Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of digital TV services face limitations in accessing desired information, as the amount of information provided through electronic program guides is limited, making it difficult to obtain relevant content-related information.
Innovation Solution
A digital device and controlling method that obtain content information currently being outputted, extract associated keywords, and retrieve relevant information using these keywords to provide users with desired information through an associated search term.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If electronic program guide is used to provide content information, then users can obtain basic program schedules, but the amount of information provided is limited and users cannot access desired content-related information
Solution Approach 1:
The patent introduces an intermediary information retrieval system that acts as a mediator between the limited EPG data and user information needs. This system automatically extracts keywords from content, generates search queries, and retrieves additional information from external sources, thereby bridging the information gap without requiring direct user intervention in complex search operations
Solution Approach 2:
The system implements self-service by automatically performing information retrieval tasks without user intervention. The controller autonomously extracts keywords from current content, generates appropriate search queries, and retrieves relevant information, eliminating the need for users to manually navigate complex search interfaces or formulate search terms
2Ease of operation
If manual search is required to obtain relevant information, then users can access specific content, but the operation becomes complex and time-consuming
Solution Approach 1:
The system performs preliminary actions by automatically extracting keywords from the currently displayed content and pre-generating search queries before the user even requests information. This advance preparation eliminates the need for users to manually input search terms or navigate through search interfaces, significantly reducing both operational complexity and time requirements
Solution Approach 2:
The information retrieval system operates autonomously by self-extracting keywords from content, self-generating search queries, and self-retrieving information without user intervention. This self-service mechanism transforms a previously manual, time-consuming process into an automatic, instantaneous operation

AI summary
A digital device and controlling method thereof are disclosed. The digital device according to an embodiment of the present invention includes a display unit configured to output a content and a controller. The controller is configured to obtain content information of the content being outputted, obtain at least one associated keyword corresponding to the obtained content information, retrieve at least one piece of associated information related to the content using an associated search term containing the obtained at least one associated keyword, and to output the retrieved at least one piece of the associated information.
