TV Browser Content Conversion for Heterogeneous Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for capturing screen content from a TV browser on a smartphone are hindered by noise issues, poor image quality, and inefficient data sharing, especially when dealing with heterogeneous devices with different control structures.
Innovation Solution
A method and apparatus that detect and convert browsing content from a TV browser into data suitable for an external device, allowing seamless transmission and sharing by requesting and processing data based on the external device's capabilities through a communication network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user directly takes a picture of the screen using the smartphone's camera, then the screen content can be captured, but noise is captured depending on the frequency at which the smartphone's sensor or TV updates, and the sensor may not easily recognize the captured data due to poor image quality
Solution Approach 1:
The patent introduces a browser extension as an intermediary component that bridges the TV browser and smartphone. The extension captures screen content through structured data extraction (DOM, CSS, JSON) rather than direct image sensing, eliminating the noise and recognition issues of direct camera capture while maintaining ease of operation.
Solution Approach 2:
The patent replaces the mechanical/optical camera system with a digital data extraction system. Instead of using the smartphone camera to photograph the screen, the system extracts browsing content as structured data (HTML, CSS, JSON) through the browser extension, substituting physical imaging with digital data capture.
2Ease of operation
If captured data is stored and shared as images, then the screen content can be shared, but a large amount of data traffic is generated
Solution Approach 1:
The patent extracts only the essential browsing content data (DOM structure, CSS styles, JSON metadata) rather than capturing complete screen images. This extraction approach retains the necessary information for sharing while dramatically reducing data volume and traffic requirements.
Solution Approach 2:
The patent changes the data representation parameter from binary image data to structured text-based data (HTML, JSON). This parameter transformation maintains information fidelity while reducing data size, enabling efficient sharing with minimal data traffic.
3Adaptability or versatility
If remote UIs are provided to control heterogeneous devices with different control structures, then device control is enabled, but the remote UIs are most likely not suited to each other and require separate stacks
Solution Approach 1:
The patent implements a universal browser extension framework that works across heterogeneous devices (smartphones, tablets, computers) without requiring device-specific stacks. The extension uses standardized web technologies (HTML, CSS, JSON) that can be universally interpreted, enabling one extension to control multiple device types.
Solution Approach 2:
The patent standardizes the control interface parameters using web-standard data formats (JSON, HTML, CSS). This parameter standardization allows the same extension to adapt to different devices by interpreting standardized data rather than requiring device-specific control structures, reducing system complexity.

AI summary
Methods and apparatuses for converting content are provided. A predetermined request signal from an external device is received. All or a portion of currently browsed content is converted into data that can be browsed on the external device, based on information about the external device contained in the predetermined request signal. The data is transmitted to the external device.
