Image Data Transmission via Dual USB Port Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current USB ports have limited transmission bandwidth, making it challenging to smoothly transmit high-resolution image data, such as 4K or higher resolution videos, at desired frame rates without excessive cost.
Innovation Solution
The method involves dividing high-resolution image data into two equal parts and transmitting each part through two lower transmission specification ports, such as USB ports, which are then combined by a software driver layer to reconstruct the original image data.

Engineering Contradiction Analysis
1Speed
If a higher transmission bandwidth port is used to transmit 4K60 fps image data, then the transmission capability is improved, but the cost increases significantly
Solution Approach 1:
The patent divides the image data into two separate parts and transmits them through two different USB ports simultaneously. This segmentation allows the system to use lower bandwidth ports (e.g., two USB 3.2 Gen1 ports with 5 Gbps each) instead of requiring a single high-bandwidth port, thereby reducing cost while maintaining the ability to transmit 4K60 fps uncompressed video data
2Manufacturing precision
If a USB 3.2 Gen1 port is used to transmit uncompressed 4K image data, then the transmission capability is improved, but the frame rate is limited to 30 fps
Solution Approach 1:
By dividing the image data into two parts and transmitting them through two ports simultaneously, the system effectively doubles the transmission capacity. This allows uncompressed 4K video to be transmitted at 60 fps using two USB 3.2 Gen1 ports, meeting the commonly accepted frame rate requirement while maintaining image quality
Solution Approach 2:
The patent employs parallel transmission where both USB ports operate simultaneously to transmit different parts of the image data. This continuous parallel action ensures that the full 60 fps frame rate is achieved without interruption or sequential processing delays

AI summary
The present invention provides an image data transmission method and an image processing module. The image data transmission method comprises following steps: separating an image data into a first part and a second part by an image processing module; outputting the first part and the second part from a first connection port and a second connection port of an image processing module to a third connection port and a fourth connection port of a computer device; combining the first part and the second part by a software driver layer of the computer device to obtain combined data; and decoding the combined data by an application layer of the computer device to display the image data. Wherein the first connection port and the second connection port have the same transmission specification, and the first part and the second part have the same size in each frame of the image data.
