    Abstract: 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 of the frames.

    Abstract translation: 所要求保护的主题提供了有助于描述，通信，利用等与结合实时视频通信的帧依赖结构的系统和/或方法。 例如，可以使用协议来将发送方的依赖关系结构传递给接收方。 此外，如果由于先前的帧丢失而被显示，接收机侧的机制可以检测将被伪造的帧; 这种机制可以利用关于帧的依赖关系结构的接收机方面的知识。

    Abstract: Protocol architecture for wiring media streams and specifying mixing behavior in a multipoint control unit. The protocol provides the capability to expose the core mixing algorithms to modification for mixing media without dealing with the functionality of the mixer itself (e.g., ports and IP specifics). The protocol facilitates the wiring of input media streams to output media streams by changing the mixing behavior via changes to the mixing algorithms using the protocol. The protocol operates based on a schema that includes controls related to route, wire, and filter for the mixer input and mixer output.

    Abstract translation: 用于布线媒体流的协议架构，并指定多点控制单元中的混合行为。 该协议提供了将核心混合算法暴露于对混合介质进行修改而不处理混频器本身的功能（例如，端口和IP特定）的能力。 该协议便于通过使用该协议通过改变混合算法来改变混合行为来输入媒体流的布线来输出媒体流。 该协议基于包括与混频器输入和混频器输出的路由，有线和滤波器相关的控制的模式进行操作。

    Abstract: 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.

    Abstract translation: 错误校正系统基于预测的分组丢失的影响以及基于帧间间隔的帧的重要性来确定应用于要由发送端点发送到接收端点的视频数据帧的纠错保护级别， 帧依赖性，帧大小，丢包概率，历史丢包模式，中央处理单元（CPU）负载和可用网络带宽。 在接收端点，当检测到特定帧的分组丢失时，接收端点将尝试使用与视频数据一起接收的保护分组来恢复帧。

    Abstract: A method and system for outputting a call announcement based on presence information of a callee as a ringback tone is provided. The announcement system is provided with presence information of users. When the telephone system receives an indication of an incoming call from a caller, the telephone system identifies the callee. After the callee is identified, the announcement system retrieves the presence information for the callee and generates an announcement based on that presence information.
