Wireless Communication Device HDMI Connection Status Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices, such as HDMI dongles, fail to display images on a display device if the HDMI cable is not coupled, preventing users from executing intended operations.
Innovation Solution
A wireless communication device that includes a processor which adds or omits specific information elements (IEs) for different wireless communication methods based on the connection status with a display device, ensuring seamless communication via Miracast or Wi-Fi standards when the HDMI or USB connections are established or removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wireless communication device transmits image data without checking HDMI cable connection status, then the device can operate continuously, but the image is not displayed on the display device and the user's intended operation is not executed
Solution Approach 1:
The wireless communication device dynamically adjusts its communication method based on the connection status of the HDMI cable. When the HDMI cable is connected, the device switches to wired communication mode; when disconnected, it switches to wireless communication mode. This dynamic adaptation ensures both continuous operation and reliable image display by selecting the appropriate communication path based on real-time conditions.
2Adaptability or versatility
If the wireless communication device supports multiple communication methods (HDMI and wireless), then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The wireless communication device automatically detects the connection status of the HDMI cable and autonomously selects the appropriate communication method without requiring user intervention. The device monitors itself and switches between wired and wireless modes based on its own detected state, thereby reducing the operational complexity for users while maintaining multiple communication capabilities.
3Ease of operation
If the wireless communication device switches communication methods based on HDMI cable connection, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The device performs automatic detection and switching of communication methods based on HDMI cable connection status without requiring user intervention. The control logic monitors the connection state and autonomously transitions between wired and wireless modes, simplifying user operation while encapsulating the complexity within the device's internal control system.

AI summary
A wireless communication device includes a first wireless communication circuit, a first terminal, and a processor. The first wireless communication circuit executes receiving first image information by a first wireless communication method, and transmitting wireless connection destination information. The processor executes adding information representing that communication is performed by the first wireless communication method to the wireless connection destination information, when the first terminal is coupled to a display device, and not adding the information representing that communication is performed by the first wireless communication method to the wireless connection destination information, when the first terminal is not coupled to the display device.
