Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display systems face challenges in transmitting control signals efficiently over long distances due to signal attenuation, leading to non-real-time control experiences and limitations in applications requiring numerous control commands, especially when the data volume of the control signal is increased with higher image resolution.
Innovation Solution
The proposed solution involves rearranging the timing sequence of signals on a coaxial cable to include additional control signal intervals within the vertical and horizontal synchronization signal intervals, allowing for increased data volume of the control signal without altering the time length of these intervals, and encoding methods that enable multiple bits to be transmitted per signal cycle, enabling simultaneous transmission of control and analog image signals.

Engineering Contradiction Analysis
1Manufacturing precision
If the data volume of the analog image signal is increased with higher resolution, then the image quality is improved, but the time required to transmit the analog image signal increases, causing the digital control signal interval to be shortened and control signal transmission to be incomplete
Solution Approach 1:
The patent segments the control signal transmission into multiple intervals: the original digital control signal interval and additional control signal intervals inserted within the vertical synchronization signal interval and horizontal synchronization signal interval. This segmentation allows control signals to be transmitted continuously across multiple frames without extending the analog image transmission time, thereby maintaining both high image resolution and complete control signal transmission.
2Loss of information
If the digital control signal interval is shortened to increase the analog image interval, then the analog image transmission time is increased, but the control signal transmission activity cannot be completed within a single frame
Solution Approach 1:
The patent performs preliminary action by inserting additional control signal intervals into the synchronization intervals in advance. This allows the control signal transmission to be prepared and executed across multiple frames proactively, ensuring that the control signal is transmitted completely without compromising the analog image signal integrity, while maintaining efficient control transmission through predetermined interval allocation.
3Adaptability or versatility
If multiple control commands or parameters are transmitted, then the control functionality is enhanced, but the control signal transmission time increases and real-time control response is degraded
Solution Approach 1:
The patent ensures continuity of useful action by continuously transmitting control signals across multiple frames using the original digital control signal interval plus additional intervals inserted in synchronization periods. This continuous transmission approach allows multiple control commands and parameters to be sent without interruption or delay, maintaining real-time control response while enhancing control functionality with increased command capacity.

AI summary
An image display system increases the data volume of a control signal in a frame of analog image so as to process an analog image in real time. A method for increasing the data volume of the control signal, which is used in the image display system, includes increasing the time for transmitting the control signal, changing an encoding method of the control signal to increase a data volume which is transmitted in unit time or outputting an analog image signal and the control signal at the same time. Therefore, the data volume of the control signal in a frame of image can be increased.
