Image display apparatus and control method for image display apparatus
First Claim
1. An image display apparatus for receiving a image signal having a predetermined format and displaying said image signal, comprising:
- a image signal receiving section which receives a composite signal containing a image signal comprising a plurality of image frames, a synchronization signal corresponding to said image signal, and a transmission index signal substituted for one part of said image signal, and outputs said image signal and said synchronization signal;
an image frame selection section which multiply selects image frames to be displayed on its own device from said plurality of image frames, based on the transmission index signal output from said image signal receiving section, and simultaneously outputs a plurality of image signals corresponding to the selected plurality of image frames; and
an image display section which displays a image signal corresponding to the plurality of image frames output from said image frame selection section.

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.
