Add more HDMI ports to a television, DVD or Blu Ray player
With HDMI connections commonplace in most television, DVD, Blu-Ray and audio equipment these days, there may not be enough HDMI connections on LED / LCD televisions.
An HDMI switch is required to add more ports. You would connect the master HDMI cable to the television or monitor, and all the HDMI components to the switch. You may then switch between each HDMI device by using a remote control.
HDMI over network or wireless HDMI
You can extend the distance between HDMI devices by using an HDMI extender such as 1080p broadcaster or a wireless HDMI video kit.
The video signal is carried either by wifi or by a network cable.
