Universal Signal Mapping for Multi-User UI Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require multiple extension devices for each user when connecting information apparatuses and UI devices, particularly for video signals, which leads to increased wiring and equipment costs.
Innovation Solution
An information processing system that includes an information apparatus with mapping, multiplexing, and transmission units to convert and transmit UI signals in a standardized frame structure, and a reception device with separation and demapping units to decode and output the signals to UI devices, eliminating the need for separate extension devices for each signal standard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extension devices are provided for each user and each video signal standard, then reliable signal transmission is achieved, but device complexity and equipment cost increase significantly
Solution Approach 1:
The transmission device is designed to handle multiple video signal standards (HDMI, DisplayPort, DVI, etc.) through a single universal interface. The signal conversion unit converts various input signal standards into a standardized frame structure that can be transmitted over the network, eliminating the need for multiple dedicated extension devices for different signal standards.
Solution Approach 2:
A network server acts as an intermediary between the transmission device and reception devices. The transmission device sends signals to the network server, which then distributes them to multiple reception devices. This intermediary approach allows one transmission device to serve multiple users and devices simultaneously, reducing the total number of extension devices needed.
2Adaptability or versatility
If separate extension devices are used for each video signal standard, then signal compatibility is ensured, but ease of installation and wiring simplicity deteriorate
Solution Approach 1:
The system changes the parameter representation of video signals by converting various video signal standards into a common frame structure format. This parameter transformation allows different signal standards to be unified into a single transmission format, simplifying the installation process while maintaining compatibility with multiple signal standards.
3Reliability
If multiple extension devices are deployed for multiple users, then individual signal transmission quality is maintained, but equipment cost and wiring quantity increase
Solution Approach 1:
Multiple video signals from different users are merged into a single standardized stream by the transmission device. The signals are converted to a common frame structure, multiplexed, and transmitted through a single network connection to the network server, which then distributes them to multiple reception devices. This merging approach maintains signal quality while reducing the total number of extension devices required.
