Abstract

The invention relates to an improved back-projection system which is based on an information point (1) comprising a screen and a keyboard (10) and which is equipped with a projection screen (4) for the projection of dynamic advertising or information images which are reflected by a mirror (3). The invention employs computer (7) and multimedia (5) means and uses the projection unit (2) as an image transmission device, said unit being formed by two synchronised projectors having adjustable light intensity. The invention also comprises an ambient light photosensor (9), noise level detection means (6) and a television and/or radio antenna (8) which, by means of precise processing, can transmit the signal received through the projection unit (2).
