1. A method for streaming media data to a client, said method comprising the steps of:
- a) encoding said media data to be streamed to said client into a first multiple description bitstream and into a second multiple description bitstream; and
b) distributing said first and second multiple description bitstreams to a plurality of servers placed at intermediate nodes throughout a network, such that said client is provided with access to said media data via a plurality of transmission paths.

Abstract
A method and system for streaming media data to a fixed client and/or a mobile client. In one method embodiment, the present invention recites encoding media data to be streamed to a client into a first multiple description bitstream and into a second multiple description bitstream. The present embodiment then recites distributing the first and second multiple description bitstreams to a plurality of servers placed at intermediate nodes throughout a network such that a client is provided with access to the media data via a plurality of transmission paths.

11. A method for achieving reliability and efficiency and for reducing single points of failure in the streaming of media data to a client, said method comprising the steps of:
-
a) encoding said media data to be streamed to said client into a first complementary multiple description bitstream and into a second complementary multiple description bitstream, each of said first and second complementary multiple description bitstreams containing complementary information, and wherein each of said first and second complementary multiple description bitstreams is independently useful to said client,; and
b) distributing said first complementary multiple description bitstream and said second complementary multiple description bitstream to a plurality of servers placed at intermediate nodes throughout a network, such that said client is provided with access to said media data via a plurality of transmission paths such that path diversity is achieved thereby eliminating potential single points of failure. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A system for streaming media data to a client, said system comprising:
-
a first server having memory coupled thereto, said first server adapted to be coupled to a network, said memory coupled to said first server having a first multiple description bitstream of encoded said media data stored thereon, said first server adapted to transmit said first multiple description bitstream of encoded said media data to a client via a first path; and
a second server having memory coupled thereto, said second server adapted to be coupled to said network, said memory coupled to said second server having a second multiple description bitstream of encoded said media data stored thereon, said second server adapted to transmit said second multiple description bitstream of encoded said media data to said client via a second path. - View Dependent Claims (21, 22, 23, 24, 25, 26)
