Abstract: A method is provided that accesses a priority and a multimedia stream to be transmitted. The priority then is embedded within the multimedia stream. The multimedia stream thereafter is transmitted. Another method is provided that receives the multimedia stream that includes the priority. Here, another priority is accessed and both priorities are compared. The control of multimedia stream transmissions to other communication devices is based on this comparison.

Abstract: In an example embodiment, a method is provided that accesses a list of communication preferences. The list identifies a communication paradigm and a different communication paradigm. Link quality information associated with the communication paradigm also is accessed. Based on the link quality information, communication may be switched from the communication paradigm to the different communication paradigm.

Abstract: A communication device and computerized method to address conflicts in Virtual Talk Groups is provided. The method may comprise accessing a database to monitor resources in a plurality of Virtual Talk Groups (VTG) to detect if there is at least a potential conflict of the resources. When the potential conflict is detected, the method comprises identifying at least one resource which is contributing to the potential conflict, and initiating automatically an electronic communication to identify the potential conflict. In response to the electronic communication, a new VTG may be initiated and terminals of administrators associated with the conflicting resource may be assigned to the new VTG. Each administrator may administer an associated VTG.

Abstract: A method and apparatus for unicast and multicast media processing is provided. The method may comprise receiving multicast packets communicating a plurality of media streams from a plurality of communication endpoints. Each communication endpoint may have an associated individual media stream. The method inspects the multicast packets to identify each individual media stream with which the packet is associated and individually processes each individual media stream. At least one individual media stream is unicast from its associated buffer to a unicast communication endpoint of the plurality of communication endpoints. In an example embodiment, the method may identify media capabilities of the unicast communication endpoint. The plurality of media streams may form part of a virtual talk group (VTG) in an audio conference.
