Benefits of technology

This patent describes a system for managing communication among multiple devices using a virtual multipoint control unit. The system includes a virtual imaging device, a virtual audio device, a virtual video mixer, and a virtual audio mixer. Each device has its own application for decoding audio and video data streams, which are then combined using the virtual video mixer and virtual audio mixer. The virtual imaging device is mapped to each application, while the virtual audio device is mapped to each application. The virtual video mixer receives the decoded video data stream from each application via the virtual imaging device, while the virtual audio mixer receives the decoded audio data stream from each application via the virtual audio device. This allows for seamless communication among the devices and ensures that each device has a consistent user experience. The system can be used in a communication network to manage communication among multiple devices.

Problems solved by technology

Most of these applications use different call control protocols and media formats (i.e. video / audio encoding and decoding formats), making them incompatible with each other.
In addition, various UC applications typically operate with different media formats, thereby causing these applications to become incompatible with each other for communicating audio, video, or data streams.
The standalone hardware is extremely costly whereas the web-based central host does not support ad-hoc communication among the UC applications running on terminals that are not connected to the same central host.
As a result, the multipoint control unit induces an unwanted delay during execution of simultaneously received data streams from different UC applications

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).

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority and the benefits of the earlier filed Provisional U.S. Application No. 61 / 859,358, filed Jul. 29, 2013, which is incorporated by reference for all purposes into this specification.TECHNICAL FIELD[0002]This disclosure relates to unified communication systems. More specifically, this disclosure invention relates to a system for a virtual multipoint control unit for unified communications.BACKGROUND ART[0003]Several Unified Communications (UC) software applications have proliferated into the enterprise communications market. These applications allow end-users to communicate using voice, video, application and data sharing, instant messaging, etc. A few examples of these applications include Microsoft Lync, Skype, IBM Sametime, Cisco IP Communicator, etc.[0004]Most of these applications use different call control protocols and media formats (i.e. video / audio encoding and decoding formats), making them incompat...
