摘要： Individual adjustment of audio volume and video properties in a computer network conference environment is provided. For audio adjustment, a buffer collects incoming streams; a stream decoder decodes the buffered audio streams, a gain adjustment applies a gain increase or decrease to the individual audio stream, and a mixer combines each of the individual signals together. The gain adjustment module receives input from a user interface control associated with each participant, and adjusts the volume of that participant's stream accordingly. If a requested increase in gain would cause an overflow of the signal, only a gain increase that will avoid such overflow is applied. Video properties such as brightness, contrast and saturation are also adjustable. Properties of the user's transmitted audio and video streams are also adjustable.

摘要： In one aspect, a request to initiate a video conference is received from a caller. The request identifies one or more called parties for the video conference. A request for the video conference is sent to one of the called parties. The called party does not accept the request. In response to a lack of acceptance of the request by the called party, a videomail service is provided. A videomail message from the caller is recorded. The caller is the sender of the videomail message and the called party is the recipient of the videomail message. The called party is notified that he has a videomail message.
摘要翻译：一方面，从呼叫者接收到发起视频会议的请求。该请求识别视频会议的一个或多个被叫方。向视频会议的请求发送给被叫方之一。被叫方不接受该请求。响应于被叫方未能接受请求，提供录像服务。记录来自呼叫者的视频信息。呼叫者是视频消息的发送者，被叫方是视频消息的接收者。被叫方被通知他有一个视频信息。

摘要： A method (and corresponding system and computer program product) for efficiently routing a multi-person conference to reduce bandwidth usage and latency is described. Computing devices used by the participants to participate in the conference are separated into proximity pools based on direct accessibility. For each proximity pool, a computing device is selected as the key node. Only the key node communicates directly with a server, and redistributes data received from the server to its pool peers. Communications between computing devices within a same pool are routed directed to one another. Proximity pools can be refined to factor in distances among the computing devices. Multiple servers may be used to reduce latency. Proximity pools are assigned to nearby servers. Communications between computing devices in different proximity pools are routed through the server(s) associated with the different proximity pool.
摘要翻译：描述了用于有效地路由多人会议以减少带宽使用和延迟的方法（以及相应的系统和计算机程序产品）。参与者参加会议的计算设备将分为基于直接可访问性的邻近池。对于每个邻近池，选择计算设备作为关键节点。只有关键节点直接与服务器通信，并将从服务器接收的数据重新分配给其池对等体。相同池中的计算设备之间的通信被路由到彼此。接近池可以被改进以计算计算设备之间的距离。可以使用多个服务器来减少延迟。邻近池被分配到附近的服务器。不同邻近池中的计算设备之间的通信通过与不同接近池相关联的服务器路由。

摘要： In one aspect, audio streams are added to a mix until the mix is either complete (i.e., all audio streams have been added) or the mix is closed early (i.e., before the mix is complete). In another aspect, audio and video streams are synchronized by playing back the audio stream and then synchronizing display of the video frames to the playback of the audio stream.
摘要翻译：在一个方面，将音频流添加到混合中，直到混合完成（即，已经添加了所有音频流）或者混合早期关闭（即在混合完成之前）。在另一方面，音频和视频流通过播放音频流同步，然后将视频帧的显示同步到音频流的回放。
