Abstract

La présente invention concerne un système de commutation visiophonique qui a des fonctions d'enregistrement et de transmission. Le système comprend de multiples terminaux visiophoniques et un dispositif de reproduction servant à reproduire des données sur un support d'enregistrement audio et vidéo, et une unité de commande de communication permettant la communication multi-points et servant à interconnecter les terminaux visiophoniques via une ligne de communication. L'unité de commande de communication établit une connexion entre un premier terminal visiophonique et un deuxième terminal visiophonique. Si le deuxième terminal visiophonique est mis en état d'attente, les données audio et vidéo sont envoyées du dispositif de reproduction au premier terminal visiophonique. Afin de permettre la transmission en état d'attente, une connexion entre un troisième terminal visiophonique et le deuxième terminal visiophonique est établie. Lorsque le deuxième terminal visiophonique (ou le troisième) est raccroché, une connexion entre le premier terminal visiophonique et le troisième terminal visiophonique (ou le deuxième) est établie.
