Transmitter Device HDMI Type-C Interface Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video and audio streaming systems often fail to function when the transmitter device and the video and audio providing device do not share the same transmission interface, preventing seamless streaming.
Innovation Solution
A transmitter device equipped with both HDMI and Type-C transmission capabilities, along with a processing unit that preferentially selects the HDMI stream for wireless transmission, while also utilizing the Type-C cable for power and optional secondary stream reception, enabling continuous operation even if the HDMI connection is lost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the transmitter device supports only one transmission interface, then the device complexity is reduced, but the adaptability to different video and audio providing devices deteriorates
Solution Approach 1:
The transmitter device incorporates multiple transmission interface conversion units (HDMI, Type-C, DisplayPort) that can convert different interface signals to a unified internal format. This allows the device to support multiple video and audio providing devices with different interfaces while maintaining a relatively compact internal structure through shared processing resources.
2Reliability
If the transmitter device prioritizes HDMI stream reception, then the streaming quality is improved, but the reliability deteriorates when HDMI connection is lost
Solution Approach 1:
The processing unit performs preliminary detection of connection status for multiple interfaces (HDMI, Type-C, DisplayPort) and pre-establishes fallback pathways. When the primary HDMI connection is detected as lost or disconnected, the system can immediately switch to alternative interfaces without interruption, ensuring continuous streaming operation.
Solution Approach 2:
The system continuously monitors the status of HDMI and alternative interface connections through feedback signals from the conversion units. Based on this real-time feedback, the processing unit dynamically adjusts the active reception path, switching from HDMI to alternative interfaces when connection quality degrades or disconnects, thereby maintaining reliable streaming.

AI summary
A transmitter device adapted to be coupled to an image providing device and a receiver device includes first and second conversion units, a wireless module, and a processing unit. The first conversion unit and the second conversion unit are configured to be coupled to the image providing device through an HDMI transmission cable and a Type-C transmission cable, respectively, so as to respectively receive a first video and audio stream and a second video and audio stream provided by the image providing device. The wireless module is connected to the receiver device through wireless communication. The processing unit preferentially selects the first conversion unit to receive a first video and audio signal output by converting the first video and audio stream by the first conversion unit and transmits the first video and audio signal to the receiver device through the wireless module.
