Thin-Client Terminal Using USB Serial Bus for Local Screen Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current thin-client terminal systems require a network installation and add-in peripheral cards, making it difficult for customers to implement thin-client terminal services without a computer network, limiting their ability to access high-resolution graphics and audio output.
Innovation Solution
A serial bus-based thin-client terminal system using a Universal Serial Bus (USB) interface, allowing for the provision of thin-client terminal services without a network installation, by using a USB host controller to transmit data packets between the thin-client terminal server and terminal system, and decoding/encoding user input and output data for processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a network installation and add-in peripheral cards are used for thin-client terminal systems, then high-resolution graphics and audio output can be provided, but the system complexity and maintenance requirements increase
Solution Approach 1:
The patent extracts the graphics processing functionality from the terminal system itself and relocates it to the server system. The terminal system only maintains a screen buffer for displaying graphics data received from the server, eliminating the need for complex add-in peripheral cards while preserving high-resolution graphics capability through centralized processing.
2Adaptability or versatility
If add-in peripheral cards are installed in terminal systems, then audio output and graphics capabilities are enhanced, but maintenance costs and security risks increase
Solution Approach 1:
The patent removes the need for add-in peripheral cards by extracting audio and graphics processing functions to the server system. The terminal system becomes a simple display device that receives processed data packets from the server, eliminating hardware that would require maintenance while preserving full audio and graphics capabilities through software-based processing.
3Adaptability or versatility
If terminal systems are connected to network infrastructure, then thin-client services can be provided, but the system requires network installation and becomes dependent on network availability
Solution Approach 1:
The patent uses USB communication as an intermediary between the terminal system and server, replacing the traditional network infrastructure dependency. This allows thin-client services to be provided through a direct USB connection, eliminating the need for network installation while maintaining the ability to deliver graphics and audio output through the USB data stream.
Data Source
AI summary
In a system and method for a thin-client terminal system having a local screen buffer using a serial bus, a serial bus interface device receives encoded data from a thin-client server system. The serial bus interface device decodes the encoded data according to a serial bus data format and provides the decoded data to a thin-client control system. The thin-client control system distributes the decoded data for processing to a video processing system, an audio processing system, and an input/output control system. The thin-client control system also receives input data from input devices connected to the thin-client terminal system. The input data is processed and encoded according to the serial bus data format for transmission to the thin-client server system.
