TV Speech Recognition via Remote Microphone Digitization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in inputting textual information on TVs for Internet searches due to the lack of a keyboard and the tediousness of using a soft keyboard with remote control cursor keys, making it hard to search for videos on TV-centric systems.
Innovation Solution
A remote control device with a microphone digitizes speech signals, which are sent to a TV for speech recognition, using a processor and database to generate recognized speech and retrieve corresponding Internet addresses, either through an Internet server or locally within the TV, utilizing grammar from Internet video sites and user context like closed captioned text.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a keyboard is provided with a TV, then text input capability is improved, but device complexity and user experience consistency deteriorate
Solution Approach 1:
The patent replaces the mechanical keyboard system with a speech recognition system. Instead of requiring physical key presses, users speak their search queries directly into a microphone, and the system converts speech to text automatically. This eliminates the need for a physical keyboard while maintaining text input capability, thereby reducing device complexity while preserving ease of operation.
2Ease of operation
If a soft keyboard is used with cursor keys, then text input capability is provided, but operation time and user convenience deteriorate
Solution Approach 1:
The patent replaces the mechanical cursor key navigation system with automated speech recognition. Instead of requiring users to manually navigate through a soft keyboard using cursor keys and select characters one by one, users simply speak their search query and the system automatically processes it. This dramatically reduces the time required for text input while maintaining full text input capability.
3Ease of operation
If speech recognition is performed, then ease of operation is improved, but device complexity and processing requirements worsen
Solution Approach 1:
The patent introduces an intermediary speech recognition service that processes speech-to-text conversion. This intermediary layer handles the complex processing requirements externally, allowing the TV system to benefit from speech recognition capabilities without needing to implement the complex speech processing algorithms itself. The intermediary service absorbs the computational burden while providing simple voice-activated functionality to the user.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and user-friendly video search on TVs by allowing voice commands to be recognized and translated into Internet addresses, enhancing the user experience by simplifying the input process and providing accurate search results.
Implementation Method 1
A microphone is on the remote control device and the remote control device digitizes speech signals representing a desired video site or video subject from the microphone
Data Source
AI summary
Speech representing a desired video site or video subject is detected and digitized at a TV remote, and then sent to a TV. The TV or in some embodiments an Internet server communicating with the TV use speech recognition principles to recognize the speech, enter a database using the recognized speech as entering argument, and return a link to an Internet site hosting the desired video. The link can be displayed on the TV for selection thereof by a user to retrieve the video.
