The problem with many new flat-panels is that they only have one HDMI input. If you're adding an Apple TV or perhaps a new video camera (or maybe both) you may find that your digital cable box/DVR is hogging the only HDMI port on your panel.
The XtremeHD 4-Port HDMI Switcher (US$99) from XtremeMac is a simple solution that lets you connect up to four devices to a single HDMI port on your TV.
Just connect your devices—cable/satellite box, Apple TV, HDTV, DVD player, HD DVD, gaming console to the input ports on the switcher then connect the switcher to your panel using a single HDMI to HDMI cable. Features inlude:
The box allows you to switch between devices using an infrared remote, a universal remote, or the button on the front of the unit. An LED on the front of the unit will indicate which source you have selected.
