摘要： A technique for reducing information reception delays is provided. The technique reduces delays that may be caused by protocols that guarantee order and delivery, such as TCP/IP. The technique creates multiple connections between a sender and recipient computing devices and sends messages from the sender to the recipient on the multiple connections redundantly. The recipient can then use the first arriving message and ignore the subsequently arriving redundant messages. The recipient can also wait for a period of time before determining which of the arrived messages to use. The technique may dynamically add connections if messages are not consistently received in a timely manner on multiple connections. Conversely, the technique may remove connections if messages are consistently received in a timely manner on multiple connections. The technique can accordingly be used with applications that are intolerant of data reception delays such as Voice over IP, real-time streaming audio, or real-time streaming video.
摘要翻译：提供了用于减少信息接收延迟的技术。该技术减少了可能由保证订单和传递的协议（如TCP / IP）引起的延迟。该技术在发送方和收件人计算设备之间创建多个连接，并且在冗余的多个连接上将消息从发送方发送到接收方。接收者可以使用第一个到达的消息，并忽略随后到达的冗余消息。收件人还可以等待一段时间才能确定要使用的到达消息。如果在多个连接上不及时地接收到消息，则该技术可以动态地添加连接。相反，如果在多个连接上一致地接收到消息，则该技术可以去除连接。因此，该技术可以与不耐受诸如IP语音，实时流音频或实时流视频之类的数据接收延迟的应用一起使用。

摘要： Encoded signal reuse implementations are described. In one implementation, an already encoded signal may be selected, in a favor of encoding a signal, if a parameter associated with the already encoded signal substantially matches an evaluation parameter used to select an encoding procedure. The implementations may also enable selection of an already encoded signal if encoding a signal would produce an encoded signal that is substantially the same as the already encoded signal.
摘要翻译：描述了编码信号重用实现。在一个实现中，如果与已经编码的信号相关联的参数基本上与用于选择编码过程的评估参数匹配，则可以选择已经编码的信号有利于编码信号。如果编码信号将产生与已经编码的信号基本上相同的编码信号，那么这些实现方式还可以使得能够选择已经编码的信号。

摘要： Various technologies and techniques are disclosed that improve media communications. In one embodiment, a media server receives a media communication with a first quality from a personal computer with VoIP telephone capabilities. The media server translates the media (e.g., audio, visual, etc.) communication into a second quality, and forwards the media communication to a communication gateway. The translation to improve communications can also be done when receiving the media communication from the communication gateway for forwarding to the persona computer having VoIP telephone capability. In some embodiments, a media server sits in the communication channel between a personal computer with VoIP telephone capabilities and a communication gateway and is able to translate communications into codec protocols they each understand.

摘要： A method and system for dynamically altering the transmission settings of one or more computing devices engaged in a real-time communication session is presented. The devices exchange meaningful and dummy control packets according to a standard control protocol. The approximate bandwidth available on the network is then calculated based on the difference in arrival times between at least one of the dummy control packets and at least one of the meaningful control packets. Once the approximate bandwidth available on the network is computed, the one or more devices adjust outgoing audio and video data streams using a quality control mechanism. The quality control mechanism enables the one or more devices to transmit data in a way that maximizes the user experience during the real-time communication session.

摘要： An architecture for developing new media activities and deploying the newly developed activities in a reusable collaboration session is provided. The architecture comprises a base collaboration session, a base activity class, and a well defined contract between the base activity class and the collaboration session. The base collaboration session provides signaling plane functionality, including session management services and media negotiation services. The base activity class provides the base class support needed to build or develop activities derived from the base activity class. The well defined contract enables the base activity class and the base collaboration session to work together to hide the details of the signaling plane from the derived activities.
