Le procédé de transmission de données exécuté par le dispositif mobile comporte les étapes consistant à: recevoir une instruction de demande de données provenant d'au moins un dispositif parmi une pluralité de dispositifs terminaux, l'instruction de demande de données étant utilisée pour demander un flux de données d'au moins une source parmi une pluralité de sources; et en réponse à l'instruction de demande de données du ou des dispositifs parmi la pluralité de dispositifs terminaux, transmettre, sur la base d'une bande de fréquences spécifiée, au moins une partie des flux de données correspondant à l'instruction de demande de données du ou des dispositifs parmi la pluralité de dispositifs terminaux, de telle façon que le ou les dispositifs parmi la pluralité de dispositifs terminaux déterminent, à partir de la partie des flux de données, un flux de données correspondant à l'instruction de demande de données émise par chaque dispositif terminal, la bande de fréquences spécifiée comportant une ou plusieurs sous-bandes de fréquences, et une correspondance existant entre les sous-bandes de fréquences et les sources. Selon le procédé de transmission de données, des images peuvent être transmises simultanément au moyen de multiples canaux de transmission de données, un utilisateur peut visualiser commodément de multiples images en temps réel, et l'agrément d'utilisation est amélioré.
