For a wide aspect ratio display, the main panel component and augmentation panel component at the transmitting end into which the horizontal line signals of hte source were decomposed are reconstituted at the receiving end by joining the previously separated components together at stitch points. In order to decrease the visibility of the stitch points in the reconstituted wide aspect ratio display, the location of the stitch point in each line is varied. The variation may be on a frame-to-frame bais or on aline-to-line basis. The latter is the preferred form, the line-to-line variation being, preferably, a random variation.
