A cropping system where the user may select a portion of a second video signal for merger or insertion into a main picture. The cropped or second signal is not altered in any way in terms of compression or other digital processing technique, but rather simply comprises user selected portion of the second image which can be selected from any position on the second image and inserted into the main picture at any position thereon. The system and method have advantages over existing PIP and POP technology in that no sophisticated and expensive electronics are required.
