    摘要: Systems and methods for error resilient transmission and for random access in video communication systems are provided. The video communication systems are based on single-layer, scalable video, or simulcast video coding with temporal scalability, which may be used in video communication systems. A set of video frames or pictures in a video signal transmission is designated for reliable or guaranteed delivery to receivers using secure or high reliability links, or by retransmission techniques. The reliably-delivered video frames are used as reference pictures for resynchronization of receivers with the transmitted video signal after error incidence and for random access.

    摘要: Systems and methods for the control and management of multipoint conferences are disclosed herein, where endpoints can selectively and individually manage the streams that will be transmitted to them. Techniques are described that allow a transmitting endpoint to collect information from other receiving endpoints, or aggregated such information from servers, and process them into a single set of operating parameters that it then uses for its operation. Algorithms are described for performing conference-level show, on-demand show, show parameter aggregation and propagation, propagation of notifications. Parameters identified for describing sources in show requests include bit rate, window size, pixel rate, and frames per second.
