Wireless transport framework with uncoded transport tunneling
Wireless transport of multiple service versions of a transport framework. First and second information may be processed for transmission, respectively, according to first and second service versions of a transport framework. The first and second information may be encoded using a first type of error correction coding; after processing, the processed first information may include error correction coding according to the first type of error correction coding, while the processed second information may remain uncoded according to the first type of error correction coding. Control information may be generated indicating that the second information remains uncoded according to the first type of error correction coding, which may signal to receivers that the second information is processed according to the second service version of the transport framework. Packets including the processed first information, the processed second information, and the control information may be generated and transmitted in a wireless manner.

wherein the first and second data comprise packetized audiovisual information, and
wherein the plurality of packets is transmitted according to a transport framework of a wireless audiovisual communication standard.
8. A non-transitory computer readable memory medium storing program instructions for transmitting packetized audiovisual information in a wireless manner, wherein the program instructions are executable to:
encode first audiovisual information using a first type of forward error correction (FEC);
encode second audiovisual information using a second type of FEC;
generate a plurality of packets, wherein the plurality of packets comprises the encoded first audiovisual information, the encoded second audiovisual information, and control information, wherein the control information indicates that the second audiovisual information is not encoded according to the first type of FEC; and
transmit the plurality of packets in a wireless manner to a remote device,
wherein the control information is usable by the remote device to determine that the second audiovisual information is not encoded according to the first type of FEC.
9. The non-transitory computer readable memory medium of claim 8 ,
wherein the control information further indicates that the second audiovisual information comprises a second service version different from a first service version of the first audiovisual information.
10. The non-transitory computer readable memory medium of claim 9 ,
wherein the second service version comprises a later service version that the first service version.
11. The non-transitory computer readable memory medium of claim 8 ,
wherein the control information is located in a different one or more packets of the plurality of packets than the first and second audiovisual information.
12. The non-transitory computer readable memory medium of claim 8 ,
wherein the first audiovisual information is located in a different one or more packets of the plurality of packets than the second audiovisual information.
13. The non-transitory computer readable memory medium of claim 8 ,
wherein at least part of the first audiovisual information and at least part of the second audiovisual information are co-located in at least one packet of the plurality of packets.
14. The non-transitory computer readable memory medium of claim 8 ,
wherein the first and second audiovisual information comprise packetized audiovisual information, and
wherein the plurality of packets is transmitted according to a transport framework of a wireless audiovisual communication standard.
15. A non-transitory computer readable memory medium storing program instructions, wherein the program instructions are executable to cause a wireless device to:
receive a plurality of packets comprising first and second encoded audiovisual information and control information in a wireless manner from a remote device,
decode the first encoded audiovisual information using a first type of forward error correction (FEC);
determine, based at least in part on the control information, that the second audiovisual information is not encoded according to the first type of FEC;
decode the second encoded audiovisual information using a second type of FEC; and
present at least one of the first decoded audiovisual information and the second decoded audiovisual information on at least one of a display and one or more speakers of the wireless device.
16. The non-transitory computer readable memory medium of claim 15 ,
wherein it is determined that the second audiovisual information is not encoded according to the first type of FEC based at least in part on a coding rate indicated by the control information.
17. The non-transitory computer readable memory medium of claim 15 , wherein the program instructions are further executable to cause the wireless device to:
determine, based at least in part on the control information, that the second audiovisual information comprises a second service version different from a first service version of the first audiovisual information.
