Title
(EN) APPARATUS, SYSTEM AND METHOD FOR DISPLAYING IMAGES ONTO A SCREEN
(FR) APPAREIL, SYSTÈME ET PROCÉDÉ POUR AFFICHER DES IMAGES SUR UN ÉCRAN
Abstract
(EN)
The invention relates to an apparatus, a system and a method for displaying images onto a screen. The apparatus can be used to display images onto the screen (4) for displaying programmes and/or messages and/or additional images which temporarily replace and/or are combined with programmes and /or messages and/or main images which are generally reproduced onto the screen (4), that is to say received by any signal transmission means and selected by the television set by means of a television tuner (2); the apparatus comprises a local processing unit (5) which detects the tuner protocols (2) to verify the configuration assumed by the television set, that is the relative instantaneous tuning of the TV set itself, in order to send corresponding signals (Sl) to a remote unit (1), connected to the local unit (5) by means of a bi¬ directional signal transmission channel; the remote unit (1), on the basis of the signals (Sl) received from the local unit (5), sends second signals (S2) to the local unit itself for commanding the beginning and the end of the display of additional programmes and/or messages and/or images onto the screen (4).
(FR)
L'invention porte sur un appareil, un système et un procédé pour afficher des images sur un écran. L'appareil peut être utilisé pour afficher des images sur l'écran (4) pour afficher des programmes et/ou des messages et/ou des images supplémentaires qui remplacent temporairement et/ou sont combinés à des programmes et/ou des messages et/ou des images principales qui sont généralement reproduits sur l'écran (4), c'est-à-dire reçus par n'importe quels moyens de transmission de signal et sélectionnés par le poste de télévision au moyen d'un syntoniseur de télévision (2); l'appareil comporte une unité de traitement locale (5) qui détecte les protocoles de syntoniseur (2) pour vérifier la configuration prise par le poste de télévision, qui est la syntonisation instantanée relative du poste de télévision lui-même, afin d'envoyer des signaux correspondants (S1) à une unité à distance (1), connectée à l'unité locale (5) au moyen d'un canal de transmission de signal bidirectionnel; l'unité à distance (1), sur la base des signaux (S1) reçus à partir de l'unité locale (5), envoie des seconds signaux (S2) à l'unité locale elle-même pour instruire le début et la fin de l'affichage de programmes supplémentaires et/ou de messages et/ou d'images supplémentaires sur l'écran (4).
