Title (EN) MEDIA BROADCAST OVER AN INTERNET PROTOCOL (IP) NETWORK
(FR) DIFFUSION DE MÉDIAS SUR UN RÉSEAU IP
Abstract:
(EN) A multimedia communication system in an Internet Protocol (IP) network includes broadcast capabilities. A system-wide emergency broadcast initiated by a user with the appropriate authority interrupts all teleconferences in progress. A group-wide high priority broadcast initiated by a user with the appropriate authority may interrupt some teleconferences in progress in the selected or other group(s). A group-wide normal priority broadcast allows all teleconferences to remain in progress and user may choose to join or not join the broadcast when the in-progress teleconference has ended.
(FR) La présente invention concerne un système de communication multimédia dans un réseau IP (Internet Protocol) comprenant des fonctions de diffusion. Une diffusion d’urgence globale à l’initiative d’un utilisateur disposant de l’autorisation appropriée interrompt toutes les téléconférences en cours. Une diffusion prioritaire de groupe à l’initiative d’un utilisateur disposant de l’autorisation appropriée interrompt certaines téléconférences en cours du groupe sélectionné ou d’autres . Une diffusion standard (priorité normale) de groupe permet la poursuite de toutes les téléconférences en cours et l’utilisateur peut choisir de participer à la diffusion au terme de la téléconférence en cours.
