TV Link via Web App Server Without Sound Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing TV link technologies require accurate sound recognition on mobile terminals, which can be unreliable, making it difficult to establish a stable connection between TV and second screen devices.
Innovation Solution
The system employs TV-specific and mobile-specific HTML documents, managed by a Web app management server, to enable communication between TV and mobile terminals without the need for sound recognition, using a Web app on the TV to synchronize content display on both devices through a Web app management server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sound recognition is used on mobile terminal to establish TV link, then device compatibility is improved, but recognition accuracy deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism (device identification signal transmission through TV output interface and mobile terminal input interface) to replace the sound recognition approach. This intermediary enables direct device pairing without relying on acoustic signal processing, thus resolving the contradiction between compatibility and accuracy.
Solution Approach 2:
The patent replaces the acoustic field-based sound recognition system with an electrical/electronic signal transmission system through standardized interfaces. This substitution eliminates the inherent limitations of sound recognition (background noise, accuracy) while maintaining device compatibility through universal interface standards.
2Reliability
If sound recognition accuracy is enhanced on mobile terminal, then link reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the link establishment function from the mobile terminal's sound recognition capabilities and relocates it to the TV device. The TV transmits device identification signals through its output interface, and the mobile terminal simply receives and processes these signals, significantly reducing mobile terminal complexity while maintaining link reliability.
Solution Approach 2:
The TV device performs self-service by generating and transmitting its own device identification signal through the output interface. This eliminates the need for the mobile terminal to perform complex sound recognition and analysis, thereby reducing mobile terminal complexity while ensuring reliable link establishment.
3Measurement precision
If HTML documents are used for content synchronization, then information linking accuracy is improved, but system complexity increases
Solution Approach 1:
The patent employs HTML documents as a universal information carrier that can represent various types of content (text, links, multimedia references) in a standardized format. This universal approach enables accurate information linking between TV and mobile terminal while avoiding the need for proprietary or complex custom protocols, thus reducing overall system complexity.
