Abstract:
This disclosure describes a system and method for negotiating video camera and display capabilities in a multi-camera/multi-display video conferencing environment. The method includes the at least one processor (120, 210, 218) determining negotiation information associated with a group of local devices (112). The negotiation information includes relative spatial information and data stream characteristics. The method also includes the at least one processor (120, 210, 218) defining the determined negotiation information in a predetermined format compatible with at least one remote device (114). The method further includes the at least one processor (120, 210, 218) applying the determined negotiation information for negotiating capability of at least one device (112-1) among the group of local devices (112) and the at last one remote device (114) for data communication.
Abstract:
This disclosure describes a virtual multipoint control unit (112, 300) for unified communications. The virtual multipoint control unit (112, 300) communicates with multiple devices (102, 104) over a network (106). The control unit (112, 300) includes multiple unified communication (UC) applications (208, 314) being executed on the devices (102, 104). The UC applications (208, 314) decode received audio data stream and video data stream. A virtual imaging device (214) and a virtual audio device (216) are mapped to the UC applications (208, 314). A virtual video mixer (210) receives the decoded video data stream from the UC applications (208, 314) via the virtual imaging device (214). A virtual audio mixer (212) receives the decoded audio data stream from the UC applications (208, 314) via the virtual audio device (216).
