Motherboard Image Transmission via Network Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image transmission interfaces, such as VGA cables, struggle to handle high-resolution image signals effectively, especially over long distances, leading to increased cable costs due to the difficulty in manufacturing long HDMI cables.
Innovation Solution
A motherboard design that incorporates an image transmission port, an on-board VGA card, a switching circuit, and a network connection port, allowing for the selective use of external or internal image signals and Ethernet network data for output, utilizing a single network cable to transmit both image and Ethernet data, reducing the need for additional image transmission cables and lowering costs.

Engineering Contradiction Analysis
1Length of moving object
If a long HDMI transmission cable is used to transmit high-resolution image signals over long distances, then the image transmission capability is improved, but the cable manufacturing difficulty increases and price becomes prohibitively high
Solution Approach 1:
The patent combines image signal transmission and Ethernet network data transmission into a single cable system. The network cable that originally carried only data now simultaneously carries both image signals and network data through separate transmission paths, eliminating the need for a separate long HDMI cable and reducing overall system cost.
Solution Approach 2:
The patent makes the network cable multi-functional by enabling it to perform both its original network data transmission function and a new image signal transmission function. This universal approach allows a single cable type to serve multiple purposes, avoiding the need for specialized long HDMI cables that are difficult and expensive to manufacture.
2Reliability
If a separate HDMI cable is used for image transmission, then image signal quality is maintained, but the number of cables and connection ports increases
Solution Approach 1:
The patent merges image signal transmission and network data transmission into a single physical cable connection. By integrating both functions into one cable system with appropriate switching circuits, the patent reduces the number of cables and connection ports while maintaining image signal quality through dedicated transmission paths.
3Adaptability or versatility
If conventional VGA cables are used for high-resolution image transmission, then compatibility is maintained, but transmission bandwidth is insufficient
Solution Approach 1:
The patent creates a universal transmission system that can handle both conventional VGA signals and high-resolution image signals through the same network cable infrastructure. The system maintains compatibility with traditional interfaces while providing the bandwidth necessary for high-resolution transmission through the enhanced network cable capability.

AI summary
A motherboard is capable of outputting image data and includes an image transmission port, an on-board video graphics array (VGA) card, a switching circuit, a control circuit, and a first network connection port. The image transmission port is configured to receive an external image signal. The on-board VGA card is configured to provide an internal image signal. The switching circuit selectively uses the external image signal or the internal image signal as image data. The control circuit selectively uses the image data or Ethernet network data as output data. The first network connection port is configured to transmit the output data.
