6. The method of claim 4 further comprising determining a remaining time of the media file in the first format by subtracting the played time from the total time of the media file in the first format, and including the remaining time in the request for the second portion of the media file in the second format.
7. The method of claim 1 wherein determining the content received ratio of the media file in the first format comprises determining a remaining time ratio of remaining time to total time of the media file in the first format.
8. The method of claim 1 wherein the media gateway is configured to determine the second portion of the media file in the second format based on the content received ratio of the media file in the first format included in the request for the second portion of the media file in the second format.
9. The method of claim 1 wherein the first wireless network comprises a third generation (3G) wireless network and the second wireless network comprises a fourth generation (4G) wireless network.
10. The method of claim 1 wherein performing the handoff to the second wireless network comprises performing a hard handoff to the second wireless network, and wherein the first wireless network and the second wireless network are different network types.
11. A wireless communication device comprising:
a wireless communication transceiver configured to receive a first portion of a media file in a first format transmitted from a media gateway over a first wireless network via progressive download, and perform a handoff to a second wireless network;
a processing system configured to determine a content received ratio of the media file in the first format that indicates the first portion of the media file in the first format received by the wireless communication device, and generate a request for a second portion of the media file in a second format; and
the wireless communication transceiver configured to transfer the request for the second portion of the media file in the second format for delivery to the media gateway over the second wireless network, wherein the request for the second portion of the media file in the second format includes the content received ratio of the media file in the first format and wherein the second format of the media file comprises a different number of bytes than the first format of the media file, and receive the second portion of the media file in the second format transmitted from the media gateway over the second wireless network via progressive download.
12. The wireless communication device of claim 11 wherein the processing system configured to determine the content received ratio of the media file in the first format comprises the processing system configured to determine a byte ratio of received bytes to total bytes of the media file in the first format.
13. The wireless communication device of claim 11 wherein the processing system configured to determine the content received ratio of the media file in the first format comprises the processing system configured to determine a remaining bytes ratio of remaining bytes to total bytes of the media file in the first format.
14. The wireless communication device of claim 11 wherein the processing system configured to determine the content received ratio of the media file in the first format comprises the processing system configured to determine a time ratio of played time to total time of the media file in the first format.
15. The wireless communication device of claim 14 wherein the processing system configured to determine the time ratio of the played time to the total time of the media file in the first format comprises the processing system configured to determine the played time and the total time from a media player configured to play the media file in the first format on the wireless communication device.
16. The wireless communication device of claim 14 further comprising the processing system configured to determine a remaining time of the media file in the first format by subtracting the played time from the total time of the media file in the first format, and to include the remaining time in the request for the second portion of the media file in the second format.
17. The wireless communication device of claim 11 wherein the processing system configured to determine the content received ratio of the media file in the first format comprises the processing system configured to determine a remaining time ratio of remaining time to total time of the media file in the first format.
