    Abstract: Digital media communication systems and methods are disclosed in which a set of end points and/or clients are in communication with a set of servers. The system is capable of determining which end point is a dominant user and/or speaker. When the system determines that an end point is dominant, then the digital data that emanates from dominant end point is preferred. Such preferred digital data may be forwarded asynchronously and possible ahead of digital data from other, non-dominant end points. Synchronous and/or substantially contemporaneous digital data from other end points may be mixed that such that, when rendered, gives substantially the same effect real life superposition of signals. The system may also toggle on or off between states of asynchronous forward and synchronous-only modes.

    Abstract translation: 公开了数字媒体通信系统和方法，其中一组端点和/或客户端与一组服务器通信。 该系统能够确定哪个终点是主要用户和/或扬声器。 当系统确定端点是主导时，则优先从主导端点发出的数字数据。 这种优选的数字数据可以在来自其他非主要端点的数字数据之前被异步地转发和可能地转发。 可以混合来自其他端点的同步和/或基本上同时代的数字数据，使得当被渲染时，给出基本相同的效果信号的真实生活叠加。 系统还可以在异步正向和仅同步模式的状态之间切换或关闭。

    Abstract: Voice communication method and apparatus and method and apparatus for operating jitter buffer are described. Audio blocks are acquired in sequence. Each of the audio blocks includes one or more audio frames. Voice activity detection is performed on the audio blocks. In response to deciding voice onset for a present one of the audio blocks, a subsequence of the sequence of the acquired audio blocks is retrieved. The subsequence precedes the present audio block immediately. The subsequence has a predetermined length and non-voice is decided for each audio block in the subsequence. The present audio block and the audio blocks in the subsequence are transmitted to a receiving party. The audio blocks in the subsequence are identified as reprocessed audio blocks. In response to deciding non-voice for the present audio block, the present audio block is cached.
