摘要： 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. In response to receipt of the positive selection notification, the source EP being configured to transmit data for receiving by the requesting EP.

摘要： 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.
