摘要： The present disclosure relates to playback of video/audio streaming media data. The media stream is available from the network at multiple bit rates. When a seek operation is performed, a playback device requests a lower bit rate media stream in order to quickly fill a playback buffer so that playback can commence more readily. After a seek start-up period is complete, the playback device can return to downloading the media stream associated with higher bit rates in order to increase the quality of the playback.

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： Estimation of available bandwidth on a network uses packet pairs and spatially filtering. Packet pairs are transmitted over the network. The dispersion of the packet pairs is used to generate samples of the available bandwidth, which are then classified into bins to generate a histogram. The bins can have uniform bin widths, and the histogram data can be aged so that older samples are given less weight in the estimation. The histogram data is then spatially filtered. Kernel density algorithms can be used to spatially filter the histogram data. The network available bandwidth is estimated using the spatially filtered histogram data. Alternatively, the spatially filtered histogram data can be temporally filtered before the available bandwidth is estimated.

摘要： Computers, particularly personal computers, have become everyday communications devices, nearly as common as telephones and televisions. A big reason for this is the expansion of computer networks, such as the Internet, which allow sending and receiving information, including audio and video information, from one computer to one or more other computers. Communicating audio and video information between computers can be problematic because users have to wait for the information to be fully downloaded before viewing or hearing it and because different computers sometimes communicate using incompatible communications protocols, which prevents comprehension. Accordingly, the inventors devised new methods, software, and computer systems that support interactive data streaming (real-time exchange of multimedia data) and full-duplex communications, for example, network conferencing, using more than one communications protocol.

摘要： Systems and/or methods (“tools”) are described that provide a buffer passing mechanism, and other techniques. Some of these tools may be enabled using a computer-implemented data structure that includes a plurality of master buffers, and a plurality of slave buffers that store data elements. Some of the slave buffers are referenced by more than one master buffer. Some of the slave buffers are referenced by one of the master buffers, but not by another master buffer.

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 corrections 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，并以多次更正方式从发送方向接收方发送消息。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。
