    Abstract: Methods, systems and devices are described to avoid stalling during playback of an adaptive media stream delivered to a media player device over a network. The media device requests segments of the media stream that are received in a buffer. Buffer utilization is monitored over time to determine a rate of change, and future segment requests are adjusted based upon the determined rate of change in the buffer utilization. By making adjustments based upon the rate of change in buffer utilization, sudden changes that could otherwise affect the viewer's experience can be avoided.

    Abstract: Methods, systems, and devices are described to proactively adapt media streaming by a number of media player clients over the Internet or another data network. Each media player requests segments of an adaptive media stream for playback to a viewer. In some implementations, some or all of the media players in the system are able to measure packet loss or other indicia of issues with the data transmission. This indicia can be used to adapt subsequent requests for additional segments of the media stream. Moreover, some implementations could provide the measured packet loss or other indicia back to the server as feedback. The server, in turn, can use the feedback from the players (along with any other additional information) to formulate business rules that can be subsequently delivered to some or all of the players in the system. The media players can therefore adapt their segment request based upon locally measured data and/or based upon business rules that reflect system-wide conditions.
