Abstract
Streaming video to a wireless device is described. For example, one embodiment of a computer-implemented method for providing a multimedia stream to a wireless device over a wireless network comprises: receiving a request for a video stream from a wireless device; requesting the video stream from a streaming server on behalf of the wireless device; streaming the video stream from the streaming server and storing the video stream or portions thereof in a buffer; streaming the video stream from the buffer to the wireless device; detecting that the wireless device has lost communication with the wireless network; sending a command to the streaming server to pause the streaming of the video stream and maintaining a network connection to the remote streaming server; detecting that the wireless device has regained communication with the wireless network; determining a point within the video stream at which the wireless device lost communication; and resuming streaming of the video stream to the wireless device at the determined point within the video stream.
