Methods and systems for streaming data in a network. Whether the network is experiencing high packet loss may be determined by a rate control module. If high packet loss is experienced, data is encoded into multiple streams by a coder using temporal domain partitioning. If high packet loss is not experienced, then data may is encoded by using frequency domain partitioning. Unequal error protection is applied to each of the streams so more important bit planes in a bit of a stream are provided with more error protection than less important bit planes. The streams are transmitted along, respectively, independent paths to a decoder. The streams are decoded, and errors in the decoded streams are corrected by using information from one or more of the other decoded streams. The decoded corrected streams are reconstructed into the data.
