<p>A method for presenting a commercial message to the public comprises the steps of transmitting (84) a video signal to a television monitor, the video signal encoding a television program and the commercial message, and operating the television monitor via the video signal to display the television program thereon. During the display of the television program, a graphic representation related to the content of the commercial message is superimposed on a portion of the image of the television program. Simultaneously with the superimposing, a sound effect is produced which is correlated to the graphic representation and unrelated to the television program, whereby the sound effect is easily distinguishable from sounds of the television program.</p> |
