Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for connecting devices via HDMI or USB cables using LAN as a relay are inflexible, making it difficult to change the connection relationship between devices, leading to complex wiring configurations.
Innovation Solution
A data transfer system with conversion devices that include interfaces for HDMI or USB protocols and Internet Protocol (IP) communication, allowing for the conversion and transmission of signals between devices over a network, enabling easy reconfiguration of connections by modifying address information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices are connected via HDMI or USB cables directly, then connection stability is ensured, but wiring complexity increases and adaptability decreases
Solution Approach 1:
The patent introduces conversion devices as intermediaries between HDMI/USB devices and the LAN network. These conversion devices translate HDMI or USB signals into network-compatible formats, enabling indirect connection through the LAN infrastructure. This mediator approach maintains connection reliability while reducing wiring complexity by eliminating the need for direct physical cable connections between distant devices.
2Device complexity
If devices are connected via LAN as a relay, then wiring complexity is reduced, but adaptability to change connection relationships decreases
Solution Approach 1:
The patent implements dynamic connection management through the control device, which can dynamically establish, modify, and terminate connection relationships between HDMI/USB devices via the LAN network. The system allows connection paths to be reconfigured without physical cable changes, enabling flexible adaptation to different usage scenarios while maintaining simplified wiring infrastructure.
3Reliability
If fixed one-to-one connection relationships are established, then connection stability is maintained, but ease of operation for changing connections deteriorates
Solution Approach 1:
The patent replaces the mechanical cable plugging and unplugging operations with electronic connection management through the control device. Instead of physically reconnecting HDMI or USB cables, users can reconfigure connections through software control, significantly improving ease of operation while maintaining connection stability through the structured LAN infrastructure.
4Reliability
If HDMI or USB cables are run between rooms, then direct device connection is achieved, but appearance is ruined and cost increases
Solution Approach 1:
The patent extracts the signal transmission function from physical HDMI or USB cables and relocates it to the LAN network infrastructure. By taking out the long-distance connection requirement from the cable system and handling it through network protocols, the solution eliminates the need to run aesthetic-sensitive cables through walls and between rooms, reducing installation cost and preserving interior appearance while maintaining reliable device connectivity.

AI summary
An HDMI source conversion device according to one aspect of the disclosure includes an HDMI interface, an IP interface, and a converter. The HDMI interface receives a first signal based on the HDMI communication protocol. The IP interface receives address information from a control device via a network based on the Internet protocol, the control device being connected to the network, and the address information indicating the address on the network of an HDMI sink conversion device that is a device different from the control device. The converter converts the first signal based on the HDMI communication protocol into a second signal based on the Internet protocol by adding at least the address information to the first signal received by the HDMI interface. The IP interface transmits the second signal to the HDMI sink conversion device via the network.
