Smart TV Bluetooth Control for Screen Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart television projection methods are one-way and require users to operate the terminal device, causing inconvenience as they cannot control the smart television using the projected content.
Innovation Solution
Establishing a Bluetooth connection between the smart television and mobile terminal upon receiving a screen projection request, allowing control instructions to be broadcasted and executed, enabling remote control of the mobile terminal through the smart television.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen projection is performed through WIFI network protocol, then content can be displayed on smart television, but the user cannot operate the terminal application through the smart television
Solution Approach 1:
The patent introduces Bluetooth as an intermediary communication channel between the smart television and terminal device. The Bluetooth connection enables bidirectional communication, allowing control instructions to be transmitted from the television to the terminal, thus solving the one-way limitation of WIFI-only projection while maintaining content display functionality.
2Adaptability or versatility
If Bluetooth connection is established for control, then the smart television can control the mobile terminal, but the system complexity increases
Solution Approach 1:
The patent makes the Bluetooth connection optional and complementary to the existing WIFI projection mechanism. The system can operate in projection mode alone or in combined projection-plus-control mode, allowing the control functionality to be activated only when needed, thus avoiding unnecessary complexity for users who only require content display.
3Ease of operation
If the terminal device is required for operation, then control precision is maintained, but user convenience decreases
Solution Approach 1:
The patent inverts the traditional control paradigm where the terminal controls the television. Instead, it enables the television to send control instructions back to the terminal device through Bluetooth, allowing users to operate terminal applications using the television's remote control interface, thus improving convenience while maintaining control precision through the established Bluetooth communication channel.

AI summary
The disclosure discloses a smart television interaction method, a storage medium, and smart television. The method comprises: when smart television receives a screen projection request, a Bluetooth connection being established with a mobile terminal corresponding to the screen projection request according to the screen projection request and screen projection being performed; and receiving a control instruction for controlling the mobile terminal, and broadcasting the control instruction through the Bluetooth to enable the mobile terminal to execute the control instruction. According to the disclosure, when the smart television establishes a screen projection connection with the mobile terminal, a Bluetooth connection is established with the mobile terminal, and the control power of the mobile terminal is acquired through the Bluetooth so as to control the mobile terminal so that the dependence on the mobile terminal is avoided and the trouble of using the mobile terminal for a long time is solved.
