Patent

CA 2187267

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.

L'invention est un système de découpage permettant à l'utilisateur de sélectionner une partie d'un second signal vidéo en vue d'une fusion avec une image principale ou d'une insertion dans une telle image. Le signal découpé ou second signal n'est dégradé d'aucune façon par une compression ou tout autre procédé de traitement numérique; il ne comprend qu'une partie quelconque de la seconde image qui est sélectionnée par l'utilisateur et insérée à un endroit quelconque de l'image principale. Par rapport aux méthodes d'incrustation et de superposition d'images actuelles, le système et la méthode de l'invention ont l'avantage de ne nécessiter aucun dispositif électronique complexe et coûteux.
