CA 2232154

When a plurality of pictures are formed from a plurality of input signals supplied at once and displayed on the same screen, the plurality of input signals are sequentially transmitted to additional information decoding means by switching switch means at a prescribed timing, and additional information included in each input signal is detected and decoded from the plurality of input signals. Thus, the display of each picture corresponding to the additional information can be individually controlled based on the plurality of additional information.

Une pluralité de signaux d'entrée simultanés sont envoyés successivement à un système de décodage d'informations supplémentaire par commutation, à un moment prédéfini, d'un système de commutation, puis des informations supplémentaires contenues dans chaque signal d'entrée sont détectées et décodées. Une pluralité d'images correspondant aux informations supplémentaires sont ainsi générées à partir des signaux d'entrée et affichées sur le même écran.
