A client device presents streaming media and includes a stream manager, a request accelerator, and a source component coupled to the stream manager and the request accelerator for determining which requests to make. A rate selection process can make rate decisions so that the buffer is filled when it is low, avoiding erratically changing rates and can choose the correct steady rate quickly. Multimedia download strategies can be used for HTTP that allow for accurate rate estimations, achieving link capacity even if network delays and packet loss rates are high, achieving timely delivery of the stream, and achieving relatively steady download rates with little short term variability. A receiver might use multiple HTTP connections, decompose media requests into smaller chunk requests, synchronize the connections using TCP flow control mechanisms, and request data in bursts. In addition, the receiver might use an HTTP pipelining process to keep the connections busy.

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.
