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： 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： Techniques for upgrading and/or downgrading a data resource deployed on a machine from one version to another version are provided. An application component that defines the data resource may provide an up/down tool for use in changing the data resource component from one version to another version. The up/down tool comprises an up/down process and one or more version conversion rules. The up/down process utilizes the provided version conversion rules to determine the ability of the up/down tool to deploy the data resource and to actually deploy the data resource.

摘要： Architecture for enabling a communications endpoint to quickly recover from a packet loss, reducing duration of a signal dropout. A communications component sends a downlink of dependency-structured signals, such as audio and/or video signals using compressed frames between key frames. A multipoint control component (MCC) is located between the communications component and multiple endpoints, and distributes the downlink to the multiple endpoints. A frame caching component caches a key frame of the downlink. If a key frame is lost at one of the endpoints, the endpoint sends a packet loss report to the frame caching component. The key frame is resent from the frame caching component to the endpoint in response to the key frame loss. In this way, the frame caching component can respond to specific frame loss situations on any of the endpoints, without interfering with the performance on the other endpoints.
摘要翻译：用于使通信端点快速从分组丢失恢复的架构，减少信号丢失的持续时间。通信组件使用压缩帧在关键帧之间发送依赖结构信号的下行链路，例如音频和/或视频信号。多点控制组件（MCC）位于通信组件和多个端点之间，并将下行链路分配给多个端点。帧高速缓存组件缓存下行链路的关键帧。如果某个端点的关键帧丢失，则端点会向帧高速缓存组件发送丢包报告。响应于关键帧丢失，关键帧从帧缓存组件重新发送到端点。以这种方式，帧高速缓存组件可以响应任何端点上的特定帧丢失情况，而不会干扰其他端点的性能。

摘要： Architecture for enhancing the compression (e.g., luma, chroma) of a video signal and improving the perceptual quality of the video compression schemes. The architecture operates to reshape the normal multimodal energy distribution of the input video signal to a new energy distribution. In the context of luma, the algorithm maps the black and white (or contrast) information of a picture to a new energy distribution. For example, the contrast can be enhanced in the middle range of the luma spectrum, thereby improving the contrast between a light foreground object and a dark background. At the same time, the algorithm reduces the bit-rate requirements at a particular quantization step size. The algorithm can be utilized also in post-processing to improve the quality of decoded video.

摘要： Techniques for deploying, maintaining and configuring complex hardware and software systems are provided. An abstract configuration of the system describes the system's desired state. Each component of the system declares the general form of the resources it requires and an abstract representation of the versions of the services it both requires and provides. A configuration process uses the abstract configuration of the system and the descriptions of each of the components in the system to validate that the system can operate effectively, ensures that each component is in the correct state and at the right version, and generates the necessary interconnections for the application components to interoperate with each other.
