Abstract
An image signal generating unit supplies a single image signal to multiple image display units having different unit numbers. Embedded in the image signal is an index signal designating the image display units on which the image signal is to be displayed. Each image display unit compares its unit number with the index signal to select displayable frames of the image signal, preferably storing and displaying the most recent selected frame. Each image display unit can thereby display a different image. The image signal may have a standard format.
