Media broadcast over an internet protocol (IP) network

Abstract

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.

Description

technical field [0001] Embodiments of the present invention relate to multimedia communication sessions and collaboration, and more particularly to allowing multiple users to communicate with each other in real-time by delivering high-quality video, audio, images, text, and files using Internet Protocol ("IP") networks. Background technique [0002] Broadcast TV has proven to be an effective way to deliver multimedia content. This is especially true when sending content to a large audience, since the same content can be sent to thousands of viewers at the same time. This connection is not point-to-point, so content can be sent from a single source to multiple recipients. However, on an IP network, since IP network routers do not support broadcast or multicast at the IP level, broadcast or multicast at the IP level has not been widely used. [0003] While broadcast television has the advantage of easily reaching large audiences, it also has limitations. For example, the br...
