Network Messages managed by the Display Device

The protocol can be implemented on inexpensive micro controllers such as the Atmel ATmega328. Because of this the work required on the display device is very limited.

Each display device must have an Ethernet connection. To ensure zero configuration the device should use the ability for the media server to assign it's IP address. When the display device is powered up it has an IP address of and the media server will respond by assigning an IP address.

The display device must listen to messages on 2 different ports:

- One port for broadcasted messages that are shared by all devices on the network.

- One port for unicast messages where the pixels to be displayed are received and where setup parameters local to the device are read and written.
