KVM extender HDMI FullHD video and USB 2.0 via UTP network cable Cat.5e

Network cable categories define the performance, frequency, and data transmission capacity in structured cabling infrastructures.

Details and Advantages

Categorization ensures infrastructure can handle bandwidth demands and mitigates electromagnetic interference.

Note: Maximum distance is typically 100 meters per TIA/EIA standards.

HDMI (High-Definition Multimedia Interface) is a digital interface standard designed for the simultaneous transmission of uncompressed audio and video streams from a compatible source to a digital display or receiver.

This interface employs Transition-Minimized Differential Signaling (TMDS) to maintain data integrity at high frequencies. Throughout its revisions, HDMI has evolved from a basic digital video solution into a complex data bus capable of carrying 4K signals at 60Hz, dynamic metadata, and bidirectional control protocols between devices.

The mass adoption of the HDMI standard has transformed the interconnect architecture in multimedia data centers and high-performance workstations. Its ability to integrate Audio Return Channels (ARC/eARC) and Ethernet connectivity (HEC) has drastically simplified structural cabling, eliminating the need for multiple redundant analog and digital cables while ensuring signal integrity over significant distances through active equalization.

CEC Control and Multi-Streaming Integration

A critical innovation in version 2.0 is the ability to deliver simultaneous dual video streams on the same screen and up to four independent audio streams, optimizing bandwidth for multi-user applications.

Key Advantages

• Pure digital transmission avoiding D/A signal degradation.
• Full backward compatibility across all standard versions.
• Native support for high-resolution audio formats like Dolby TrueHD and DTS-HD.
• Support for 21:9 cinema aspect ratios and dynamic lip-sync.

Note: Final interface performance is dependent on the cable certification (Standard, High Speed, or Premium High Speed).

1080p, also known as Full HD, refers to a video resolution of 1920x1080 pixels using progressive scanning.

Detail

The 'p' stands for progressive scan, which eliminates the flickering often associated with interlaced video (1080i).

Advantages

• Superior image clarity for mainstream displays.
• Widely supported by all streaming platforms.

Note: 1080p remains the industry standard for high-definition quality.

A KVM switch (Keyboard, Video, Mouse) is a hardware device that allows the control of multiple computers or servers through a single set of input and output peripherals.

This technology acts as an electronic signal bridge that switches the data flow between various host units and the user console. It manages DDC/EDID signal emulation to prevent operating systems from detecting monitor disconnection during switching, ensuring the stability of display configurations and operational continuity.

The integration of KVM switches into modern infrastructures has significantly optimized rack space and reduced power consumption. With the evolution towards KVM-over-IP, administrators can remotely manage data centers at the BIOS level, enabling critical interventions regardless of the operating system state.

Key Technical Detail

Intermediate and advanced models use dedicated microprocessors for each input port, ensuring the computer "perceives" an active peripheral connection, eliminating USB enumeration latency.

Main Advantages

• Significant reduction in cabling and redundant hardware.
• Centralized and secure access to multiple systems.
• Ability to manage headless servers.

Note: KVM switches are essential for operational efficiency in data centers and server rooms.
