USB Server Pre-fetch Mechanism for Signal Transmission Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
USB over IP architectures experience significant response delays due to the need for request signals to reach peripheral devices before generating response signals, which slows down signal transmission and affects instant display and processing of game, audio, or video files.
Innovation Solution
Implementing a pre-fetch mechanism where the USB server actively sends virtual request signals to peripheral devices, allowing them to generate control signals without waiting for request signals, and the processing device intercepts and matches these signals to perform operations, thereby eliminating the need for traditional request-response signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional request-response signal transmission is used in USB over IP architecture, then device communication can be established, but response delay occurs and signal transmission speed is slowed down
Solution Approach 1:
The USB server proactively sends virtual request signals to peripheral devices before actual user operations occur, causing the peripheral devices to pre-generate control signals. This preliminary action eliminates the need to wait for request signals during actual operation, thereby reducing response delay and accelerating signal transmission speed.
2Adaptability or versatility
If USB over IP architecture is implemented to enable remote control, then position flexibility is improved, but transmission speed is reduced due to request-response protocol requirements
Solution Approach 1:
The USB server sends virtual request signals in advance to peripheral devices, causing them to pre-generate control signals. This allows the system to maintain remote position flexibility while eliminating the sequential request-response delay, thereby preserving both adaptability and transmission speed.

AI summary
A method for accelerating signal transmission in a USB network protocol architecture having a USB server, a processing device and a peripheral device connected to the USB server. The method includes: intercepting request signals sent from the processing device according to the USB network protocol; sending, by the USB server, virtual request signals to the peripheral device so as to cause the peripheral device to generate control signals corresponding to the virtual request signals; receiving, by the USB server, the control signals from the peripheral device, and transmitting, by the USB server, the control signals to the processing device; and matching, by the processing device, the control signals and the intercepted request signals so as to perform operations corresponding to the control signals. Therefore, the present invention eliminates the need to wait for the arrival of request signals before making responses, thereby accelerating the speed of signal transmission.
