Thin Client Video Transmission via Dual Communication Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thin client systems face challenges in transmitting video data over IP networks, leading to increased network load and potential loss of differential data, which results in deteriorated video quality.
Innovation Solution
The system separates the communication paths for screen data and video data, using a remote control communication path for screen data and a different logical IP network path for video data, allowing for optimal video data transmission formats and reducing network bandwidth consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video data is transmitted through the remote control communication path along with screen data, then the thin client terminal can display video content, but the amount of differential data increases significantly causing network load increase and potential data loss
Solution Approach 1:
The patent divides the communication path into two separate segments: the remote control communication path for screen data and a dedicated logical IP network path for video data. This segmentation allows each path to be optimized for its specific data type, preventing video data from increasing the differential data load on the remote control path while still enabling video transmission capability.
2Adaptability or versatility
If video data is transmitted through the remote control communication path, then video content can be displayed, but data loss occurs resulting in deteriorated video quality
Solution Approach 1:
By separating video data transmission into a dedicated logical IP network path, the patent ensures that video data does not compete with screen data for bandwidth on the remote control path. This dedicated path provides reliable video data transmission without the risk of differential data loss that would occur in the compressed remote control communication path.

AI summary
In a thin client system which provides a high-quality picture reproduction method and which makes it possible to use a thin client terminal as a TeleVision (TV) phone terminal and a TV conference terminal, a video reproducing module is disposed in a thin client server device and a graphics module is disposed in a thin client terminal. The thin client server device sets a transmission color to a video display area of screen data and sends the screen data via a remote control communication path and simultaneously sends video data via a second route. The thin client terminal receives the screen data and the video data and displays the screen and video data as an overlay image in one same screen using the screen overlay scheme.
