Abstract
A system wherein audio samples are added to a video signal, but within the time-frame allocated to video information, thereby displacing video data. Two audio samples are preferably placed in each video line: at the beginning, and at the end. When the video lines are 'stacked' to form a video image, the audio forms noisy vertical stripes at the sides of the image, each of which is about 6 percent of the width of the image. The invention stretches the video image, to cover the stripes.
