Abstract

A method for optimizing media playback quality for a wireless handheld computing device is disclosed. The system includes a client request manager that may be responsible for controlling or instructing a web browser on what file segments should be downloaded next to the wireless handheld mobile computing device to insure optimal video playback quality for the computing device. The request manager may be dynamic in that it may continually monitor elements of an application subsystem as well as the modem subsystem. The request manager may select one or more file segments for download that optimizes media playback on the wireless handheld computing device based on the data received from at least one of the application subsystem and modem subsystem.
