Dynamic USB Data Path Allocation for Simultaneous Video and Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current USB TYPE-C interfaces in large-scale screen devices prioritize video transfer over data transfer, requiring additional hardware or interfaces for simultaneous data transfer during video playback, especially at high resolutions like 4K, which can result in video delays and poor quality.
Innovation Solution
Integration of a USB hub function into display equipment with multiple USB transfer connectors, allowing dynamic separation of data paths for video and data transfer, and automatic adjustment of display settings to maintain video quality during data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the USB TYPE-C interface uses all data paths for video transfer at 4K resolution, then video quality is improved, but data transfer capability deteriorates
Solution Approach 1:
The patent implements dynamic allocation of data paths where the configuration switch can dynamically separate data paths into video data paths and data-transferring data paths based on real-time needs. This allows the system to switch between prioritizing video quality or data transfer capability as required, resolving the contradiction by making the resource allocation flexible rather than fixed.
Solution Approach 2:
The patent segments the data paths into distinct video data paths and data-transferring data paths through the configuration switch. This segmentation allows independent optimization of each function - video paths can be allocated for high-quality 4K transmission while separate data paths handle data transfer simultaneously, eliminating the zero-sum trade-off between the two functions.
2Productivity
If additional hardware equipment is added to enable simultaneous data transfer during video playback, then data transfer capability is improved, but device complexity increases
Solution Approach 1:
The patent makes the display equipment universal by integrating a USB hub function into the display device itself. The display equipment can now perform multiple functions - video display, data transfer, and file management - through its built-in USB hub capability. This eliminates the need for separate external USB hub hardware while providing the same functionality, reducing overall system complexity.
Solution Approach 2:
The patent merges the USB hub function directly into the display equipment's internal architecture. By combining the video processing unit and USB hub controller into a single integrated system, the patent enables simultaneous video playback and data transfer through the same device without requiring additional external hardware equipment, thus reducing device complexity.
3Adaptability or versatility
If the USB hub function is integrated into display equipment, then device versatility is improved, but control complexity increases
Solution Approach 1:
The patent implements self-service control where the display equipment automatically detects the connection status of electronic devices and autonomously configures the data path allocation. The control unit monitors whether a second electronic device is connected and automatically switches between video-only mode and combined video-data transfer mode without requiring manual user intervention, thereby managing control complexity through automation.
Solution Approach 2:
The patent employs feedback mechanisms where the control unit continuously monitors the connection status of electronic devices to the display equipment. Based on this feedback information, the system automatically adjusts the configuration switch settings to allocate data paths appropriately - directing all paths to video when no data transfer is needed, and separating paths when data transfer is required, thus managing complexity through intelligent feedback-driven control.
Data Source
AI summary
A data transfer device of a display equipment and a data transfer method are provided. The data transfer device of the display equipment includes a display panel, a first transfer connector, a second transfer connector, a configuration switch and a control unit. The first and the second transfer connector are in line with a universal serial bus (USB) protocol including a plurality of data paths. When a first electronic device is connected to the first transfer connector, the control unit separates the data paths of the first transfer connector into at least one video data path and at least one data-transferring data path dynamically. A video signal of the first electronic device is transferred to the display panel through the video data path, and the first electronic device and the second electronic device transfer data to each other through the data-transferring data path.
