A multi-display configuration method and a multi-display adaptor are disclosed, in which the digital content stream distributed through a network is displayed on a large screen configured of a plurality of displays, and the network, to which a plurality of the displays may be connected, is automatically set while automatically grasping the relative positions of the displays. In a system making up a screen by connecting displays having a network interface, the relative positions of the displays are extracted from the display connection. The relative positions of the displays and the network address mapping information of the displays are held. The digital content stream transmitted through the network is rebuilt into the data for the desired display, and the rebuilt data is coded by a variable length coder. The coded data is configured as a network packet and transmitted or received through the network interface.
