Media broadcast over an internet protocol (IP) network |
摘要 |
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.
