master antenna television (MATV) system, to send remote control commands
to remotely connected network devices. Each control command is addressed

addressed by a single device. The control system is configured to provide
signaling in one direction, from the control device to the network
devices. Status feed back is not provided by a network device to the
control device. Each network device is a display device, such as a
