摘要： Methods, devices, systems, and non-transitory computer-readable storage media for improving the reception of data at a computing device by proactively utilizing new TCP connections in response to identifying that TCP connections have stalled. In an embodiment, a processor of the computing device may perform operations including monitoring a status of requests via a plurality of TCP connections, identifying a stalled TCP connection having a missing request based on the monitoring, wherein the stalled TCP connection is configured to utilize a first network interface and access a first data source, evaluating other TCP connections to determine whether the other TCP connections stall using the first network interface or when accessing the first data source; identifying a second network interface and a second data source based on the evaluating, and reissuing the missing request with a new TCP connection configured to use the second network interface and access the second data source.

摘要： A client device presents streaming media and includes a stream manager for controlling streams, a request accelerator for making network requests for content, a source component coupled to the stream manager and the request accelerator for determining which requests to make, a network connection, and a media player. A process for rate estimation is provided that will react quickly to reception rate changes. The rate estimator can use an adaptive windowed average and take into account the video buffer level and the change in video buffer level in a way so to guarantee that the rate adjusts fast enough if there is a need, while keeping the windowing width large (and thus the measurement variance) large. A guarantee might be that when a rate drop or rise happens, the estimator adjusts its estimate within a time proportional to a buffer drain rate or buffer fill level.

摘要： In overview, the various embodiments provide methods implemented by a processor executing a DASH client on a receiver device for determining when, in view of a change in the receiver device's resources (e.g., bandwidth, battery power, etc.), to cancel or abandon downloading the current segment at the current representation and restart download of the current segment at a different representation to meet one or more performance objectives and/or optimizations related to the change in the receiver device's resources. In various embodiments, the receiver device processor may perform a cost-benefit analysis to determine whether switching representations during the ongoing download of the current segment will benefit the performance of the receiver device, and the receiver device processor may switch representations in response to determining that switching representations would improve the performance of the receiver device.
