Composition of DVI KVM Extender

        DVI KVM Extender is mainly composed of two parts: Sender and Receiver.

        DVI KVM extender sender: responsible for collecting, encapsulating and encoding the DVI interface video and USB signals of DVI signal source devices (such as computer hosts, server hosts, etc.), and sending them to the receiver through transmission media (such as network cables, optical fibers, etc.) terminal; its interface function is generally shown in the figure below

        DVI KVM Extender Receiver: responsible for receiving the signal from the sender, decapsulating and decoding the signal, and outputting the original DVI interface video and USB signal to the display device and USB interface keyboard and mouse; its interface functions are generally shown in the figure below Show

How DVI KVM Extenders Work

        Signal acquisition: the sending end first collects the DVI interface video and USB signal of the DVI host signal source device.

        Signal encapsulation and encoding: The collected original signal is encapsulated and encoded by the processing unit at the sending end, and the signal is converted into a format suitable for transmission on the transmission medium.

        Signal transmission: Encapsulated and encoded signals are transmitted from the sending end to the receiving end through transmission media (such as network cables, optical fibers, etc.). During the transmission process, the DVI KVM extender ensures the stability and transmission quality of the signal.

        Signal decapsulation and decoding: the receiving end decapsulates and decodes the received signal, and restores the signal to the original DVI interface video and USB signal.

        Signal output: The receiving end outputs the decapsulated and decoded signal to the display device and keyboard and mouse operation device to realize remote operation and management.

Use Cases for DVI KVM Extenders

        Data center: DVI KVM extender can realize the remote operation and management of servers in the data center, reduce the workload of on-site maintenance, and improve the operating efficiency and safety of the data center.

        Computer room monitoring: In a large computer room environment, the DVI KVM extender can realize remote monitoring and management of multiple devices, reduce the work intensity of the computer room personnel, and improve management efficiency.

        Telecommuting: With the help of DVI KVM extender, employees can remotely operate computers located in the company's server room in the office or at home, realizing efficient telecommuting.

        Education system: DVI KVM extender can transmit video signals of multiple computers to projectors or monitors in remote classrooms, which is convenient for teachers to carry out remote teaching and management.

        Business demonstration: Through the DVI KVM extender, the video signal of the demonstration equipment can be transmitted to the large-screen display in the meeting room, exhibition hall and other places to realize high-definition remote demonstration.

        Medical equipment monitoring: Hospitals can use DVI KVM extenders to realize remote monitoring and management of medical equipment, improving the efficiency and quality of medical services.

        Through the above analysis, we have a deeper understanding of the composition, working principle and practical application cases of the DVI KVM extender. As an efficient signal transmission tool, DVI KVM extender has been widely used in various fields, bringing convenience to people's work and life.
