Whenever the display, media player and content server are located apart there is a need for audio-video wiring between the display and the media player and between the media player and the content server. The connection from media player to display is normally a VGA, DVI, HDMI or Component video connection. Sometimes this signal is distributed over Cat 5 cables using transmitter and receiver baluns allowing for greater distances between display and player and simplified wiring. The connection from media player to the content server is usually a wired Ethernet connection although some installations use wireless Wi-Fi networking.
