Power State Synchronization via Wireless Remote Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in consistently controlling the power state of external input devices, particularly when using the HDMI-CEC function, and lack reliable solutions for errors in integral power control.
Innovation Solution
An electronic apparatus equipped with a wireless communicator and a processor that communicates with a remote controller to transmit control signals to external input devices, ensuring their power states match the apparatus's power state, using methods like infrared or Bluetooth communication, and includes a detection circuit to determine power states via clock signals from HDMI interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HDMI-CEC function is used for integral power control, then power state synchronization between electronic apparatus and external input device is achieved, but reliability is reduced due to optional application and manufacturing discretion
Solution Approach 1:
The patent introduces a remote controller as an intermediary device to mediate between the electronic apparatus and external input device. The remote controller receives power state information from the electronic apparatus via wireless communication and transmits appropriate control signals to the external input device, ensuring reliable power synchronization without depending on optional HDMI-CEC implementation
Solution Approach 2:
The patent replaces the wired HDMI-CEC control mechanism with a wireless communication-based control system. The electronic apparatus communicates with the remote controller wirelessly (using infrared, Bluetooth, or other wireless protocols), which then controls the external input device, eliminating the need for physical HDMI connection and CEC function dependency
2Reliability
If HDMI-CEC function is applied for integral power control, then power state consistency is improved, but device complexity increases due to optional configuration and error handling requirements
Solution Approach 1:
The system enables self-service operation where the remote controller automatically receives power state information from the electronic apparatus and autonomously determines the appropriate control signals to send to the external input device. The user simply needs to operate the remote controller, and the system handles the complex coordination and error handling automatically
Solution Approach 2:
By introducing the remote controller as an intermediary, the patent simplifies the overall system architecture. Instead of requiring direct complex communication between the electronic apparatus and external input device via HDMI-CEC, the remote controller acts as a simplified interface that handles the coordination logic and error management
