ABSTRACT:
A display having separate transmitting and receiving sets is provided with a feature to simplify adjustment to the video signal transmission path between the both sets. The display employs a directional video signal transmission path and a sub communication path using a non-directional communication medium independent from the transmission path. Fine adjustment to subtly adjust the spatial matching of the video signal transmission path is carried out using a control signal transmitted through the sub communication path. Coarse adjustment to roughly adjust the spatial matching of the video signal transmission path is carried out using a test video image displayed at the display portion of the receiving set. These fine adjustment and coarse adjustment are combined to keep an optimum spatial matching of the video signal transmission path between the sets.
