HDMI KVM extenders are devices that combine the capabilities of HDMI extenders and KVM extenders. They allow users to extend both HDMI video and audio signals as well as keyboard, video, and mouse (KVM) signals over long distances.
HDMI KVM extenders typically consist of a transmitter unit and a receiver unit. The transmitter unit is connected to the source device, which could be a computer, media player, or other HDMI-enabled device. It captures the HDMI video and audio signals and also connects to the keyboard, mouse, and possibly other USB devices. The receiver unit is placed near the user's workstation and connects to the display, keyboard, mouse, and other peripherals. It receives the extended HDMI signals and transmits them to the display while relaying the keyboard and mouse signals back to the transmitter unit.
By combining HDMI and KVM extension, HDMI KVM extenders allow users to control remote computers or devices while maintaining high-quality video and audio. This makes them suitable for various applications such as digital signage, server rooms, control rooms, and collaborative work environments.
HDMI KVM extenders often support additional features like USB extension for other USB devices, audio transmission, and sometimes even serial control or other peripheral connectivity. They provide users with the convenience of remotely accessing and controlling computers or devices while eliminating the need for physical proximity between the user and the source device.
