Abstract
Methods and apparatuses are disclosed for encoding and transmitting video or multimedia content in wireless communications networks. The methods include encoding a block of input symbols using upper layer rateless forward error correction (FEC) codes to generate a plurality of encoded packets. The rateless FEC codes may be layer-aware or may incorporate unequal error protection (UEP). The input symbols represent one or more layers of scalable encoded video or multimedia content. Each of the plurality of encoded packets is transmitted over a selected one of a plurality of wireless channels. The wireless channel is selected based on an importance level of the input symbols in the encoded packet exceeding a threshold. The threshold may vary dynamically based on conditions in the networks.
