The HDMI port on our tv is already connected to the cable box- do we have to swap out in order to hook up our new Apple TV box.

Heya- Apple Community: can't seem to find a relevant article / reference - we bought the Apple TV square- but the HDMI port is already taken on the back of our tv - as it is connected to the cable box. all the instructions assume you have available port on back of tv. Any suggestions? Do we have to plug and unplug each time or is there a solution ten thousand people already know about. :-) With thanks
