Display Device Voice Command Mediator for Content Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional TVs face challenges in searching for content using voice recognition, as content providers need to provide metadata in advance, and different search methods between TV and content providers complicate content retrieval.
Innovation Solution
A display device equipped with a network interface, memory to store content provider applications, and a controller that allows for voice-activated content requests without requiring separate applications from content providers, enabling seamless interaction with multiple content providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is implemented for content search, then user convenience is improved, but content providers must provide metadata in advance which increases system complexity
Solution Approach 1:
The patent introduces a mediator component that translates user voice commands into content provider requests without requiring the content providers to implement voice recognition themselves. This intermediary layer handles the complexity of voice processing and metadata requirements, allowing content providers to simply respond to standardized requests while users benefit from convenient voice-based content search.
2Adaptability or versatility
If different content providers use different search methods, then provider autonomy is maintained, but content search compatibility deteriorates
Solution Approach 1:
The patent creates a universal interface layer that can handle requests from multiple content providers with different search methodologies. This universal component translates various provider-specific search methods into a common format, enabling the system to maintain compatibility across different providers while preserving their individual autonomy and search capabilities.
3Measurement precision
If metadata is required in advance for voice recognition, then search accuracy is improved, but response time increases due to preprocessing requirements
Solution Approach 1:
The patent implements preliminary action by pre-processing and storing content metadata in a standardized format before voice search is initiated. This advance preparation of metadata structures enables the system to quickly match voice commands against pre-organized content information, maintaining high search accuracy while significantly reducing the time required to process and respond to user queries.
Data Source
AI summary
A display device comprises a network interface, a memory, a display unit, and a control unit. When speech is received while a content image is displayed through a content provider application, the control unit controls the network interface so as to transmit, to a content provider that provided the content provider application, request information corresponding to the speech.
