TV Remote Graphics via VPN Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively leverage televisions as larger displays for remote devices to present graphics and control applications, limiting the use of TVs as robust displays for nearby devices.
Innovation Solution
A system that includes a TV with a processor and communication interface, communicating through a virtual private network (VPN) with a wireless device to execute applications and present images on the TV display, allowing control from the wireless device, with both devices running compatible operating systems like Android.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a TV is used as a display for remote devices, then the display area is improved, but the control complexity increases due to VPN configuration and protocol encapsulation
Solution Approach 1:
The patent introduces a VPN connection as an intermediary mechanism between the wireless device and the TV. This mediator enables communication between devices with different operating systems (Android and Tizen) by establishing a secure tunnel that handles protocol translation and data routing, thus resolving the complexity of direct integration while maintaining the large display area benefit
Solution Approach 2:
The TV is designed to serve multiple functions: it acts as a display device for remote applications, a communication hub for VPN connections, and a processing unit for executing applications received from wireless devices. This multi-functionality allows the TV to handle various protocols and communication methods, reducing the overall system complexity despite the enhanced display capabilities
2Area of stationary object
If applications are executed on the TV from remote devices, then the display capability is improved, but the system reliability decreases due to compatibility issues between different operating systems
Solution Approach 1:
The VPN connection serves as a mediator that handles protocol translation and data formatting between Android devices and Tizen TV. This intermediary layer ensures that applications and control signals from the wireless device are properly formatted and transmitted to the TV, maintaining system reliability despite the heterogeneity of operating systems
Solution Approach 2:
The system dynamically adjusts communication parameters such as data encoding, packet formatting, and protocol versions based on the detected device type and operating system. This parameter adaptation ensures reliable communication between different platforms while maintaining the enhanced display capability
3Adaptability or versatility
If video rotation is implemented according to user commands, then the adaptability is improved, but the processing time increases
Solution Approach 1:
The system implements dynamic video rotation based on real-time user commands received from the wireless device. The TV processor can rotate video content according to the orientation detected or specified by the user, allowing the display to adapt to different viewing angles and positions. This dynamic adjustment is handled through efficient software processing that minimizes processing time while maintaining the desired adaptability
