Display Apparatus Keyword-Based Content Extraction in Suspended Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in finding desired broadcast content among numerous channels and contents, as existing systems lack efficient methods to provide detailed information about broadcast content beyond titles, and require manual channel scanning.
Innovation Solution
A display apparatus and method that extracts object information from broadcast content frames, determines relevant content based on user-defined keywords, and provides information even when the display is turned off, using a communicator and processor to receive and analyze data in both normal and suspended modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually scans through all broadcast channels to find desired content, then the user can identify available programs, but this process consumes excessive time and effort
Solution Approach 1:
The system performs preliminary object recognition and content analysis on broadcast frames in advance, extracting object information and generating content descriptions before the user needs to find specific programs. This allows the EPG to be pre-populated with meaningful content information rather than requiring real-time manual scanning.
Solution Approach 2:
An intermediary system comprising an object recognition server and content analysis module is introduced between the broadcast signal source and the user interface. This intermediary automatically analyzes broadcast content, extracts object information, and generates searchable content descriptions, eliminating the need for users to manually scan channels.
2Loss of information
If only broadcast title information is provided in the EPG, then the system remains simple, but detailed information about broadcast content such as objects, characters, and music cannot be verified
Solution Approach 1:
An object recognition server acts as an intermediary that performs complex image analysis and content extraction tasks remotely. The server receives broadcast frames, identifies objects, characters, and other content elements, and returns structured information to the display apparatus. This distributes computational complexity from the user device to a dedicated server infrastructure.
Solution Approach 2:
Traditional manual content verification methods are replaced with automated computer vision and machine learning systems. The object recognition server uses AI-based image analysis to automatically identify and categorize content elements, substituting human manual inspection with automated computational analysis.
3Ease of operation
If the display apparatus provides content information only when the display is on, then energy consumption is reduced, but users cannot access content information when the display is turned off
Solution Approach 1:
The system segments functionality between the display apparatus and the object recognition server. The display apparatus handles user interface and information presentation, while the server handles computationally intensive object recognition and content analysis. This allows the display to remain simple and energy-efficient while still providing advanced content information capabilities.
Solution Approach 2:
The object recognition server serves as an external intermediary that performs content analysis independently of the display apparatus state. The server can process broadcast content and generate information descriptions even when the user's display is turned off, with results available for immediate display when the user activates the device.
Data Source
AI summary
A display apparatus includes a communicator configured to communicate with an external apparatus, a memory storing one or more instructions, and a processor. The processor may be configured to execute the one or more instructions to control the communicator to receive data regarding frames forming each of a plurality of pieces of broadcast content in a normal mode; extract first object information based on the data; and provide information about broadcast content corresponding to a keyword of interest of a user from among the pieces of broadcast content, based on the first object information. When entering a suspended mode from the normal mode, the processor may be configured to control the communicator to receive second object information in the suspended mode, and provide the information about the broadcast content corresponding to the keyword of interest from among the pieces of broadcast content, based on the second object information.
