Abstract
Controlling the power state of an internet protocol (IP) network display device using the cumulative connection status of one or more client devices to presentation a gateway. The first client device to connect to the presentation gateway causes it to transmit an instruction over the IP Network to the display device to turn-on. When the last of the client connections to the presentation gateway has terminated, the presentation gateway transmits either a sleep or power-down instruction over the IP network to the display device, optionally, after a countdown timer expires.
