摘要： An error correction system determines a level of error correction protection to apply to a frame of video data to be transmitted by a sending endpoint to a receiving endpoint based on the predicted impact of packet loss as well as the importance of the frame based on inter-frame dependencies, frame size, packet loss probability, historical packet loss pattern, central processing unit (CPU) load, and available network bandwidth. At the receiving endpoint, when packet loss is detected for a particular frame, the receiving endpoint will attempt to recover the frame using protection packets received along with the video data.

摘要： Systems, methods, and/or techniques (“tools”) are described that sort speakers in a network-enabled conference. In some cases, this sorted list of speakers indicates which speaker is dominant. With this sorted list, a participant's communication device may provide context about the speakers. In some cases a participant's communication device has a display that presents real-time video of the speakers or other visual indicia, such as each or the most dominant speaker's name, picture, title, or location. These and other context about speakers may help participants better understand discussions in network-enabled conferences.

摘要： The claimed subject matter provides systems and/or methods that facilitate describing, communicating, utilizing, etc. a frame dependency structure in connection with real time video communication. For example, a protocol can be employed to communicate the dependency structure from a sender to a receiver. Moreover, a mechanism on a receiver side can detect frame(s) that will be rendered with artifacts if displayed due to previous frame loss; this mechanism can leverage receiver side knowledge concerning the dependency structure of the frames.
