HDMI switch

A device that is used to select a video source for the TV via the HDMI interface. For example, a cable box, DVD player and DVR may all have HDMI outputs, but the TV may have only one HDMI input. In this case, a three-port HDMI switch would have three HDMI inputs for the source components and one HDMI output to the TV set. When multiple TVs are used, there are HDMI switches with two or more outputs. The switch may be operated manually, by remote control or automatically by priority. When an HDMI source is turned on with a higher priority, those signals are directed to the TV. See HDMI.
