Abstract

La présente invention concerne un procédé de prévisualisation synchrone de multiples programmes de terminal, comprenant les étapes suivantes : lors de la réception d'une instruction de prévisualisation de multiples programmes de terminal, un terminal maître détecte en temps réel des modes opératoires de terminaux esclaves connectés au terminal maître ; et ensuite, l'obtention, en temps réel ou à des intervalles d'une durée prédéfinie, d'une première image de trame courante du terminal esclave dans un mode de lecture vidéo et d'une seconde image de trame courante du terminal maître ; finalement, l'affichage synchrone de la première image de trame courante et de la seconde image de trame courante dans une zone d'affichage du terminal maître. La présente invention concerne en outre un appareil pour une prévisualisation synchrone de multiples programmes de terminal. Au moyen de la présente invention, un utilisateur peut prévisualiser l'avancement de la lecture de tous les programmes de terminaux sur un terminal maître de sorte que l'utilisateur n'a pas besoin de reprendre à maintes reprises de multiples dispositifs terminaux pour confirmer l'avancement de la lecture des programmes, ce qui améliore le confort d'utilisation.
