Engineering Contradiction Analysis
1Ease of operation
If dedicated cables are installed from remote servers to the system administrator's console, then access to remote computers is enabled, but signal quality decreases and cost increases with distance
Solution Approach 1:
The system automatically measures the high-frequency signal amplitude at the receiving end and feeds this information back to the transmitting end, where the high-frequency boost circuitry is adjusted accordingly. This closed-loop feedback mechanism ensures optimal signal quality regardless of transmission distance.
Solution Approach 2:
The high-frequency boost setting is made dynamic rather than fixed. The system continuously monitors signal conditions and automatically adjusts the boost level to adapt to changing transmission characteristics, enabling reliable operation over varying distances.
2Reliability
If high-frequency boost circuitry is placed near the video source, then high-frequency attenuation is compensated, but the system requires manual adjustment and is not adaptive
Solution Approach 1:
The system performs self-adjustment by automatically measuring the received signal's high-frequency amplitude and adjusting the boost circuitry without requiring manual intervention. The system serves itself by monitoring and correcting its own signal quality.
Solution Approach 2:
Automatic feedback control is implemented where the measured signal characteristics are used to automatically adjust the high-frequency boost level, eliminating the need for manual tuning while maintaining optimal signal quality.
3Area of stationary object
If equipment and wiring are eliminated to reduce space, then space requirements decrease, but signal transmission distance increases causing attenuation
Solution Approach 1:
The high-frequency boost is made dynamically adjustable based on actual transmission distance and signal conditions. This allows the system to compensate for attenuation over longer distances that result from space consolidation, maintaining signal quality while reducing space requirements.
Solution Approach 2:
The system changes the electrical parameters of the transmission by automatically adjusting the high-frequency boost level to compensate for attenuation caused by longer transmission distances, enabling space-efficient configurations without sacrificing signal integrity.

AI summary
Disclosed is a high-frequency boost circuitry for use with a computer management system. Detection circuitry at the receiving end of a video signal measures the amplitudes of various frequency components of the video signal. If the amplitudes of the high-frequency components of the video signal are substantially lower than the amplitudes of the low frequency components of the video signal, the detection circuitry sends the amplitude information to analysis circuitry located at the transmitting end of the video signal. The analysis circuitry utilizes this information to determine the appropriate level of amplification needed for the video signal. This results in improved signal to noise ratio at the receiver in the computer management system.
