Display Apparatus Voice Search via External Server Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in quickly finding and accessing desired broadcast content on display apparatuses connected to broadcast receiving apparatuses, as they lack information about the connected device, service provider, and currently available content, requiring manual channel memorization or searching.
Innovation Solution
A method and system where the display apparatus acquires channel information, transmits voice keywords and sub-sampling data to an external server, receives content information, and displays relevant data, allowing users to search for content more efficiently and control connected broadcast receiving apparatuses through a remote controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display apparatus simply receives and displays broadcast signals from a connected broadcast receiving apparatus, then the device complexity is reduced, but the user cannot access information about the connected device, service provider, or available content
Solution Approach 1:
The patent introduces an external server as an intermediary that stores and provides information about broadcast receiving apparatuses, service providers, and available content. The display apparatus communicates with this server to obtain comprehensive information without needing to store it locally, thus reducing device complexity while preventing information loss.
Solution Approach 2:
The display apparatus is enhanced with multiple functions including voice recognition, server communication, and remote controller management. This universal approach allows a single device to handle various tasks (displaying content, recognizing voice commands, managing remote controllers) that would otherwise require separate systems.
2Loss of time
If users manually memorize channel numbers or search through channels to find desired content, then the device complexity remains low, but the time required to access content increases significantly
Solution Approach 1:
The patent replaces the mechanical/manual channel surfing process with voice recognition technology. Users can speak the name of desired content instead of manually changing channels, significantly reducing access time. The system processes voice commands and automatically navigates to the requested content.
Solution Approach 2:
The system pre-loads and organizes content information from the external server, including content names, descriptions, and location data. This preliminary preparation allows the voice recognition system to quickly match user commands with available content without requiring manual channel searching.
3Ease of operation
If the display apparatus provides comprehensive content information and remote control capabilities, then user convenience is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The external server acts as a mediator that handles complex information processing and storage tasks. The display apparatus maintains minimal local functionality for voice recognition and basic control, while relying on the server for comprehensive content management. This distribution of computational load reduces energy consumption at the display device while maintaining ease of operation.

AI summary
A method of controlling a display apparatus is provided. The method of controlling a display apparatus includes acquiring channel information regarding a broadcast content that a user watched through a broadcast receiving apparatus that is connected to the display apparatus, in response to a voice keyword being input from the user, transmitting information regarding the input voice keyword and the channel information to an external server, from the external server, receiving content information related to the voice keyword among content information that is determined based on the channel information and provided by a broadcast content providing service that the user subscribes to and displaying the content information related to the received voice keyword.
