Abstract:
1. A method of controlling transmission of streaming data between a first data processing system and a second data processing system in a packet network, the method comprising: assigning priorities to packets of the streaming data based on characteristics of the packets of streaming data; monitoring performance of transmission of the packets from the first data processing system to the second data processing system; progressively coding the streaming data to provide packets of progressively coded streaming data; wherein assigning priorities to packets of streaming data based on characteristics of the packets of streaming data comprises assigning priorities to the packets of progressively coded streaming data based on the progressive coding of the data associated with corresponding ones of the packets of progressively coded streaming data; wherein monitoring performance of transmission of the packets from the first data processing system to the second data processing system comprises monitoring performance of transmission of the packets of progressively coded streaming data from the first data processing system to the second data processing system; wherein preventing retransmission of selected ones of the packets from the first data processing system to the second data processing system based on the assigned priority of the selected ones of the packets and the monitored performance of transmission comprises preventing retransmission of selected ones of the packets of progressively coded streaming data from the first data processing system to the second data processing system based on the assigned priority of the selected ones of the packets of progressively coded streaming data and the monitored performance of transmission; and wherein progressively coding the streaming data to provide packets of progressively coded streaming data comprises progressively coding the streaming data to provide packets of progressively coded streaming data utilizing subband coding.
