Display Device Dedicated Link Control Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent television systems require users to upgrade the entire device to enhance functionality, leading to additional costs and waste, as users need to manage multiple external devices separately for control operations.
Innovation Solution
A control method and display device that utilize dedicated links through an interface component to receive and transmit control instructions between devices, allowing the display device to perform operations or forward instructions to external devices, improving control convenience and speed by encapsulating data at the application layer and matching protocols for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire television is upgraded to enhance functionality, then the display capability and intelligence are improved, but the cost increases and resource waste occurs
Solution Approach 1:
The television system is segmented into a host device and separate external functional devices (projector, sound bar, game console). Each device performs specific functions independently, allowing users to add or remove functions without replacing the entire television system, thus avoiding resource waste while maintaining adaptability.
Solution Approach 2:
The television host is designed with universal control capabilities that can manage multiple different external devices through a unified remote control interface. The host can switch between controlling the television itself and controlling various external devices, providing multi-functionality without requiring separate control systems for each device.
2Adaptability or versatility
If multiple external devices are added to enhance functionality, then the adaptability is improved, but the control complexity increases
Solution Approach 1:
The television host acts as an intermediary device between the remote control and multiple external devices. It receives control signals, determines which external device should respond based on the current operating context, and forwards appropriate commands. This mediation simplifies the control architecture by providing a single point of control rather than requiring direct control of each external device.
Solution Approach 2:
The control functions for the television host and multiple external devices are merged into a unified control system. The remote control maintains a single set of buttons that can control both the host and external devices, and the host integrates control logic for multiple devices, reducing the overall control complexity despite having multiple functional devices.
3Adaptability or versatility
If control instructions are transmitted through multiple external devices, then the control flexibility is improved, but the control time increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing the host as the central control point and pre-configuring the control signal routing paths. When control instructions are received, the host already has the capability to immediately route commands to the appropriate external device without requiring complex real-time decision-making or signal routing, thus reducing control time while maintaining flexibility.
Data Source
AI summary
The display device receives first data, including a control instruction, encapsulated at an application layer by a first external device, matching a data protocol of a first dedicated link over the first dedicated link; and if the control instruction is a control instruction directed to the display device, then the display device performs a corresponding operation according to the control instruction; and if the control instruction is a control instruction directed to a second external device, then the display device transmits the first data to the second external device over a second dedicated link so that the second external device performs a corresponding operation according to the control instruction.
