Abstract
Also in a video system in which a device responding to a multiple screen display function and a non-responding device are mixedly present, a communication message for a collaboration of the device which performs a multiple screen display operation is realized without exerting an influence on operations of the non-responding device. A video device including two or more video input ports and capable of simultaneously receiving videos output from multiple video source devices connected to the video input ports is configured so as to perform a predetermined filtering operation or message conversion when transmitting to the other video input ports a communication message for video device control to be converted through the video input ports.
