Abstract

L'invention concerne un système de transmission d'images utilisant une source de signaux programmable, un émetteur et une visionneuse portative séparée distante de l'émetteur, laquelle comporte un écran pour la présentation des images dérivées de l'information associée à la source des signaux. Cette source, programmée pour la fourniture de données images dans un format approprié à la présentation sur l'écran de la visionneuse, à partir de l'information associée à la source des signaux, fournit à l'émetteur les données images résultantes. Ensuite, l'émetteur assure la transmission sans fil de ces données à destination de ladite visionneuse, aux fins de présentation sur l'écran de la visionneuse. Les données en question constituent une diffusion statique de l'information associée à la source des signaux, qui peut être un ordinateur, un téléviseur ou une caméra vidéo.
