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.
