Smart TV Remote Display Control Using Mobile Web Browsers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for remote management and control of smart televisions are limited, as they primarily rely on proprietary protocols and are not designed for dynamic interaction with mobile computing devices, restricting seamless interactive user experiences.
Innovation Solution
A method and system that utilize standard HTTP and video tags to enable remote control of smart televisions through mobile devices, by generating messages that instruct browsers to display representations of physical user input devices, allowing users to interact with content on smart televisions using mobile devices as controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary protocols (RDP, VNC, ICA) are used for remote control, then remote management capability is achieved, but device complexity and lack of interoperability increase
Solution Approach 1:
The patent applies universality by using standard web technologies (HTTP, WebSocket, HTML5 video tags) that can serve multiple functions: displaying video content, transmitting control signals, and enabling bidirectional communication between mobile devices and televisions. This replaces multiple proprietary protocols with a single universal web-based framework that maintains remote control capability while reducing complexity.
Solution Approach 2:
The patent substitutes the mechanical/proprietary protocol-based control system with an electronic/web-based system. Instead of using specialized remote control protocols (RDP, VNC, ICA), the invention uses standard web communication protocols (HTTP, WebSocket) and HTML5 video tags to achieve the same remote control function, thereby reducing device complexity and improving interoperability.
2Ease of operation
If native applications are used on smart televisions, then control functionality is provided, but adaptability to mobile computing devices is limited
Solution Approach 1:
The patent makes the television interface universal by implementing it as a web application that can be accessed through standard web browsers on any mobile device. The television displays a web page that serves as the control interface, allowing mobile devices to interact with the television without requiring native applications on the television itself. This achieves both ease of operation and broad adaptability.
Solution Approach 2:
The patent introduces a web browser as an intermediary between the mobile device and the television. Instead of the mobile device communicating directly with native television applications, the interaction occurs through the web browser, which mediates the communication using standard web protocols. This intermediary enables seamless interaction while maintaining compatibility across different mobile devices.
3Ease of manufacture
If standard web technologies (HTTP, video tags) are used, then interoperability and ease of manufacture improve, but dynamic interaction capability is reduced
Solution Approach 1:
The patent introduces dynamics by implementing bidirectional real-time communication using WebSocket technology. The system transitions from static HTTP requests to dynamic, event-driven communication where the television can push video frames and control signals to the mobile device, and the mobile device can send control inputs back to the television in real-time. This maintains ease of manufacture using web technologies while enabling rich dynamic interaction.
Solution Approach 2:
The patent implements feedback mechanisms where the television provides real-time video feedback to the mobile device through the web browser, and control inputs from the mobile device are immediately reflected on the television display. This bidirectional feedback loop enables dynamic interaction while using standard web technologies, resolving the contradiction between implementation simplicity and interaction capability.
