What Is Video Transmission
Video transmission refers to the process of delivering video, audio, and control signals from source devices to remote displays or control systems through fiber optic, Ethernet, or coaxial cabling. Modern transmission technologies allow HDMI, DVI, SDI, USB, Ethernet, and KVM signals to be extended over long distances while maintaining image quality and signal stability for professional applications.
