摘要

To make it possible to execute the same application regardless of the number of connected panels even in a multi-panel environment. A host system, which transfers an image signal to a plurality of panels connected thereto, comprises: a panel ID recognition section for recognizing a panel ID of a single panel or a predetermined number of collected panels as a unit; a window ID allocation section for allocating a window ID to a window which is a transfer processing unit of the image signal; a control signal output section for outputting a control signal used for setting a window ID to be processed to the panel ID to be read out in transferring the image signal; and an image signal transfer section for adding the window ID allocated by the window ID allocation section to the image signal, thus transferring the image signal.
