Abstract: This disclosure describes a Chroma-based video converter that includes a first interface that receives the video signal to be encoded. The converter includes a frame splitter configured to receive one or more RGB frames, the frame splitter splits the RGB frame into R data, G data, and B data. The converter further includes a framing module configured to convert the received RGB frame into a first YUV frame and a second YUV frame. The converter additional includes an encoder configured to encode the first YUV frame and the second YUV frame based on a timestamp as that associated with the RGB frame. The converter further includes a multiplexer configured to multiplex the encoded first YUV frame and the encoded second YUV frame to generate a single encoded signal. And, the converter includes a second interface that transmits the generated single encoded video signal.

Abstract: This disclosure describes a computer-implemented method for a control mechanism for video output. Additionally provided is a video stream that is generated from the video source and encoded by the video encoder, where the video stream further comprises one or more video frames with each video frame including a time stamp that includes timing and clocking information. Additionally provided is a video display apparatus that includes a video display apparatus processor, video display apparatus memory, video decoder, and a video frame buffer, where the video decoder decodes the encoded video stream, and the video display apparatus generates a pixel clock. Additionally provided is a desired latency threshold for displaying a first video frame with respect to a second video frame that includes an upper threshold limit and a lower threshold limit. The disclosed method includes the following steps that control jitter in the displayed video stream.

Abstract: This disclosure describes a virtual multipoint control unit in communication with one or more unified communication (UC) applications on one or more host devices over a network that allows ad hoc UC conferences between UC applications from different vendors. The virtual multipoint control unit includes a host device coupled to a network. In addition, the unit includes one or more unified communication (UC) applications being executed in software instructions. The virtual multipoint control unit virtualizes the physical audio devices to be shared simultaneously between multiple UC applications and allows ad hoc UC conferences between said UC applications from the same and or different UC vendors.

Abstract: A multi end-point (EP) conferencing system, including a decentralized scalable network of End-Points that includes a source EP being configured to connect to a non-virtual target EP. The source EP being configured to transmit to the non-virtual target EP a conference list thereof, for distributing to non-virtual EPs and virtual EPs associated with the target EP. It is further configured to receive a conference list of the non-virtual target EP, integrate the received conference list with its conference list to obtain an integrated conference list and distribute the integrated conference list or parts thereof to virtual EPs and non-virtual EPs associated with the source EP. The source EP being further configured to receive a positive selection notification being indicative of a requesting EP from EPs associated with the source EP that would like to get data from the source EP.

Abstract: This disclosure describes an apparatus (106) for improving performance of a multipoint control unit (210). The apparatus (106) provides a video stream manipulator (208) and a multipoint control unit (210). The video stream manipulator (208) may encode one or more video streams in a predetermined video codec standard separately. Each of the encoded video streams includes at least one encoded video frame made of a plurality of macroblocks, where the macroblocks are segregated into a predetermined number of macroblock lines. The multipoint control unit (210) may assemble predetermined number of macroblock lines from each of the encoded video streams in a predetermined composition.

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.
