Wireless transport framework with uncoded transport tunneling
First Claim
1. A method for transmitting an audiovisual stream to a mobile device in a wireless manner, wherein the mobile device comprises a receiver implementing a physical layer, the method comprising:
- generating a first plurality of packets, wherein the first plurality of packets comprises audiovisual information;
generating control information, wherein the control information comprises commands for modifying operation of the physical layer by the receiver, wherein said modified operation comprises modifying the processing of audiovisual information by the receiver in the physical layer;
modulating the control information using a pseudorandom sequence to obtain encoded control information, wherein the pseudorandom sequence is known by the mobile device;
generating a second plurality of packets, wherein the second plurality of packets comprises the encoded control information;
transmitting the plurality of packets to the mobile device in a wireless manner, wherein the plurality of packets comprises the first plurality of packets and the second plurality of packets.

Abstract
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.
