Abstract

A system and method for wirelessly transmitting audiovisual information. A first plurality of packets including audiovisual information may be generated. A second plurality of packets including error correction coding information for the audiovisual information may be generated. Control information for associating the error correction coding information with the audiovisual information may be generated, and a third plurality of packets including the control information may also be generated. The plurality of packets, including the first, second, and third pluralities of packets, may be transmitted to a mobile device in a wireless manner. The control information may inform the mobile device of the association of the first error correction coding information with the audiovisual information.

Claims

1. A wireless device, comprising:

an antenna; and

receiver logic,

wherein the antenna and the receiver logic are configured to;

receive control information indicating that a first stream and a second stream are associated;

receive the first stream, wherein the first stream comprises audiovisual information and forward error correction;

receive the second stream, wherein the second stream comprises audiovisual information and forward error correction,

wherein the audiovisual information comprised in the first stream and the audiovisual information comprised in the second stream are at least partially complementary; and

associate the first stream and the second stream based at least in part on the control information.

2. The wireless device of claim 1, wherein the wireless device further comprises a display and one or more speakers, wherein the wireless device is further configured to:

process the audiovisual information comprised in the first stream and the audiovisual information comprised in the second stream together; and

present the processed audiovisual information using the display and the one or more speakers.

3. The wireless device of claim 1,

wherein the first stream is also configured for processing and presentation by a wireless device without the second stream.

4. The wireless device of claim 1,

wherein the forward error correction comprised in the first stream comprises different forward error correction relative to the forward error correction comprised in the second stream.

5. The wireless device of claim 1, wherein the wireless device is further configured to:

receive control information indicating that the first stream is transmitted at a different time than the second stream.

6. The wireless device of claim 1,

wherein the control information is received separately from the first stream and from the second stream.

7. A system, comprising:

receiver logic configured to cause a wireless device to;

receive control information indicating that a first stream and a second stream are associated;

receive the first stream, wherein the first stream comprises audiovisual information and forward error correction;

receive the second stream, wherein the second stream comprises audiovisual information and forward error correction; and

associate the first stream and the second stream based at least in part on the control information.

wherein the audiovisual information comprised in the first stream and the audiovisual information comprised in the second stream are at least partially complementary.

14. A system, comprising:

transmit logic configured to cause a transmission system to;

generate a first stream, wherein the first stream comprises audiovisual information and forward error correction;

generate a second stream, wherein the second stream comprises audiovisual information and forward error correction;

generate control information indicating that the first stream and the second stream are associated;

transmit the first stream;

transmit the second stream; and

transmit the control information.

15. The system of claim 14, wherein the transmit logic is further configured to cause the transmission system to:

receive an audiovisual content stream, wherein both the first stream and the second stream are generated based at least in part on the received audiovisual content stream.

16. The system of claim 14,

wherein the first stream is also configured for processing and presentation by a wireless device without the second stream.

17. The system of claim 14,

wherein the forward error correction comprised in the first stream comprises different forward error correction relative to the forward error correction comprised in the second stream.

18. The system of claim 14, wherein the transmit logic is further configured to cause the transmission system to:

transmit the second stream at a different time than the first stream,

wherein the control information further indicates that the second stream is transmitted at a different time than the first stream.

19. The system of claim 14,

wherein the control information is transmitted separately from the first stream and from the second stream.

20. The system of claim 14,

wherein the audiovisual information comprised in the first stream and the audiovisual information comprised in the second stream are at least partially complementary.
