Abstract
A technique capable of realizing more suitable image output and the like for an own apparatus is provided with respect to communication among apparatuses in a system including a video display apparatus. A video display apparatus provided with an apparatus-apparatus communication interface (for example, an HDMI) holds own apparatus information. In a case where a video output apparatus is connected to a video input unit of the video display apparatus via a first apparatus-apparatus communication interface and a video output unit of the video display apparatus is connected to an external video display apparatus via a second apparatus-apparatus communication interface, external apparatus information is obtained from the external video display apparatus via the second apparatus-apparatus communication interface, and apparatus information (EDID) is provided to the video output apparatus via the first apparatus-apparatus communication interface.
