Smart TV Control via WiFi Aware Mobile Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infrared remote controls for smart televisions have limitations such as short operation distance, poor anti-interference, and instability, and cannot share resources with mobile terminals effectively.
Innovation Solution
Establishing a WiFi Aware connection between a smart television and a mobile terminal to enable remote control and file sharing through WiFi Aware and WiFi Direct connections, allowing the mobile terminal to send control instructions and file data to the smart television.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If infrared remote control is used, then simple control function is achieved, but operation distance is short and anti-interference capability is poor
Solution Approach 1:
The patent replaces the optical infrared transmission mechanism with a WiFi-based wireless communication system. The mobile terminal captures images of the remote control buttons using a camera, recognizes the button patterns, and transmits control commands via WiFi to the television. This substitution eliminates the line-of-sight requirement and distance limitations of infrared transmission while maintaining the simplicity of remote control operation.
2Ease of operation
If infrared remote control is used, then control function is achieved, but stability and anti-interference capability are poor
Solution Approach 1:
The patent replaces the vulnerable infrared transmission system with a WiFi-based communication system that offers superior stability and anti-interference capabilities. WiFi communication provides more robust signal transmission, better penetration through obstacles, and higher reliability in maintaining control connections compared to infrared technology.
3Ease of operation
If infrared remote control is used, then basic control is achieved, but resource sharing capability is lacking
Solution Approach 1:
The patent implements a multi-functional system where the mobile terminal serves multiple purposes: it acts as a remote control device for basic television operations, a camera for capturing images, and a file transfer interface for resource sharing. The WiFi connection enables the mobile terminal to not only control the television but also share files, media, and other resources between the terminal and television, greatly enhancing the system's versatility.
4Reliability
If WiFi Aware connection is established, then operation distance is extended and stability is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the mobile terminal automatically searches for and connects to the television's WiFi Aware service without manual intervention. The system automatically establishes the WiFi connection, handles authentication, and sets up the communication channel between the terminal and television, reducing the user burden while managing the complexity of the connection establishment process.
Data Source
AI summary
A method for controlling a smart television is disclosed. The method includes establishing a WiFi Aware connection with a mobile terminal when the smart television receives a subscription request of the mobile terminal; and sending a message by the mobile terminal to the smart television through the WiFi Aware connection to control the smart television.
