Problem
Current HDMI repeater configurations are inconvenient and complex, requiring pre-designated input and output ports, leading to potential user frustration and unsatisfactory experiences due to the rigidity in handling different types of HDMI connections.
Innovation Solution
The implementation of auto-detection and adaptive configuration techniques in HDMI ports, allowing the same connector to dynamically function as either an input or output based on the connected device's mode, using detection components, control components, and switching circuits to automatically configure the HDMI transceiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-designated input and output ports are used in HDMI repeater configuration, then the device structure is simple and reliable, but the ease of operation deteriorates and device complexity increases due to multiple dedicated ports
Solution Approach 1:
The HDMI connector is designed to serve multiple functions by detecting the connected device type (source or sink) and automatically configuring itself accordingly. The same physical connector can function as either an input or output port depending on the detected device mode, eliminating the need for separate dedicated input and output connectors.
Solution Approach 2:
The HDMI connector's functional configuration is made dynamic through automatic detection of the connected device's operational mode. The connector transitions between different functional states (input mode or output mode) based on real-time detection signals, allowing the system to adapt its configuration without manual intervention.
2Adaptability or versatility
If multiple dedicated input and output ports are provided, then the adaptability to different connection types is improved, but the device complexity and ease of operation worsen due to rigid architecture
Solution Approach 1:
A single HDMI connector is designed to handle multiple connection scenarios by detecting whether the connected device is a source or sink. This universal connector replaces what would traditionally require separate dedicated ports for different connection types, reducing architectural complexity while maintaining versatility.
Solution Approach 2:
The functional parameters of the HDMI connector (input/output mode) are changed dynamically based on detection signals from the connected device. The system modifies its operational parameters automatically, allowing the same physical infrastructure to adapt to different connection types without requiring multiple dedicated ports.
3Reliability
If dedicated input and output ports are used, then the reliability of signal transmission is improved, but the ease of operation deteriorates due to potential incorrect connections
Solution Approach 1:
The HDMI connector performs self-configuration by automatically detecting the operational mode of the connected device and adjusting its own functional state accordingly. This self-service capability eliminates the need for users to manually configure connection types or worry about incorrect connections, as the system autonomously ensures proper signal transmission routing.
Solution Approach 2:
The system uses feedback from detection signals to determine the operational mode of connected devices and automatically configures the HDMI connector's function. This closed-loop feedback mechanism ensures reliable signal transmission by continuously monitoring connection status and adjusting the connector configuration accordingly, while simultaneously improving ease of operation.
