摘要： The present disclosure relates to playback of video/audio streaming media data to provide a glitch-free experience. The system adapts the media stream to the user connection in order to provide the glitch-free experience. Stream selection can be made using a heuristics module located on the playback device that analyzes various aspects of the playback to make intelligent decisions about which media stream to download from a network.

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： 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： A codec selection process is independent of a codec source. A codec table may be used that includes indexed codec references related to codecs stored in a codec source. The codec table and the codec source may be modified without affecting a codec selection process. This feature of an exemplary implementation makes it fairly straightforward to add, change, or otherwise modify codecs stored in the codec source and referenced in the codec table without having to change the codec selection process.

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 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.
