摘要： A method is provided in one example and includes receiving a request to establish a video session between a first user and a second user. The request is sent by the second user by dialing an identifier string associated with the first user. The method also includes evaluating whether the first user has accepted the request. If the first user has not accepted the request over a designated interval, then the second user is directed to an element configured for recording a videomail message for access by the first user. The method also includes identifying the first user has accepted the request, and establishing the video session between the first user and the second user.

摘要： A method is provided in one example and includes receiving a request for a video session and establishing the video session between a first user and a second user. The method further includes communicating a first stream of packets associated with signaling data that propagates to a first network, which provides a first network connection to the first user. The method also includes communicating a second stream of packets associated with media data that propagates to a second network, which provides a second network connection to the second user. The media data can include audio data and video data.

摘要： A method, an apparatus, and logic encoded in a computer-readable medium to carry out a method. The method includes receiving packets containing compressed video information, storing the received packets in a buffer memory, timestamping the received packets according to an adjustable clock; and removing packets from the buffer for decoding and playout of the video information, the removing according to playback order and at a time determined by the adjustable clock. The method includes adjusting the adjustable clock from time to time according to a measure the amount of time that the packets reside in the buffer memory, such that time latency caused by the buffer memory is limited. An overrun or an underrun of the buffer memory is unlikely.

摘要： Elements in a video conferencing system may respond to error message(s) by aggregating any related error messages and responding based on a severity of the error indicated by the related error messages. A multipoint control unit (MCU) may identify an active stream from a first endpoint and forward the active stream to a second endpoint. The active stream may include a plurality of packets and transmit a video image by sending a frame followed by sub-frame modifications. The MCU may receive an error message from the second endpoint and determine the error's severity, which is related to an impact on an displayed image. Based on the severity, the MCU may identify and send a set of correction packets to the second endpoint. Also, a third endpoint may receive the active stream and respond to one or more error messages received from the second endpoint.
摘要翻译：视频会议系统中的元素可以通过聚合任何相关的错误消息并基于相关错误消息指示的错误的严重性来响应错误消息。多点控制单元（MCU）可以从第一端点识别活动流并将活动流转发到第二端点。活动流可以包括多个分组，并且通过发送帧跟随进行子帧修改来发送视频图像。 MCU可以从第二端点接收到错误消息，并确定错误的严重性，这与对显示的图像的影响有关。基于严重性，MCU可以识别并发送一组校正分组到第二端点。而且，第三端点可以接收活动流并响应从第二端点接收到的一个或多个错误消息。

摘要： A method is provided in one example and includes receiving a video input from a video source coupled to a display configured for rendering a user interface thereon; evaluating a plurality of pixels within the video input; and determining if a particular pixel within the pixels is associated with a color that matches a designated value associated with a chroma-key. If a match is found for the particular pixel, then the particular pixel is rendered as a clear image on the display, and if the match is not found, the particular pixel is darkened by a certain percentage.
