Image display apparatus and control method for image display apparatus

Abstract

An object is to reduce the time and trouble at the time of switching pages, by displaying two or more pages at the same time on one image display apparatus. A image signal generator 11 outputs a net of image signal, a synchronization signal corresponding to the net of image signals, and a transmission index signal substituted for one part of the net of image signals, and applies these in parallel to the image display apparatuses 13 and 14. In the case where a plurality of image display apparatus numbers are set for the image display apparatus 13, the image display apparatus numbers together with the locations where the signals for the respective image display apparatus numbers are displayed are set. In an image display apparatus for which the image display apparatus number and the transmission index signal are compatible, the net image signal contained in the frame having the image display apparatus number from the image signal side is compressed so that the image signal can be displayed relative to the number of the image display apparatuses which numbers are set, and is displayed on the image display section of the appropriate image display apparatus 13.
