A component switcher is a television or computer accessory that switches between multiple component video inputs to multiple display devices with compatible outputs.
An HDMI switcher is a component switcher that accepts input from multiple HDMI sources and sends the chosen signal to the HDTV or monitor through one HDMI cable.
Video switching is a technology that splits a composite video signal into its individual color components. Since the three color components travel through the switcher in parallel, it produces a sharper and crisper picture than traditional switchers.
